EXECUTIVE SUMMARY
The research conducted basically focused on the assessment of the market potential
of CNG engine oil and market share estimation of the individual competitors. From
the data obtained after primary research it can be concluded that Lucknow has
ample scope in the CNG engine oil market with the market potential of 37kltrs
(approx.)
Study of the market share revealed that MAK GE is the market leader in the CNG
engine oil industry in Lucknow with the market share of 34%. Indian Oil
Corporation Limited and British Petroleum are the other companies performing
quite well with the market share of 22% each (approx.).
Through the market research it was also found that Lucknow has approximately
120 counters which are stocking CNG engine oil out of which only 40% entertain
the Gulf CNG supreme. There is approximately 1500 mechanic garages
specialized in CNG engine repairs including all big and small garages.
The customers of CNG engine oils are basically the auto drivers and the bus
drivers who are very Price sensitive customers. The trucks in Lucknow are still
diesel driven therefore the study of the buying behavior of truck drivers was out of
the scope of study.
The research came up with the astonishing fact that Castrol GTX is ruling the mind
of the customers by positioning itself as the premium product in the market. The
factors which guide the buying behavior of the customers are quality, price,
promotional activities and different schemes being offered in the market.

OVERVIEW OF THE
LUBRICANT INDUSTRY
These are exciting time for the lube industry in India. Each one of the vast
contingent of 22 multinationals and a total of 80 big and small players are vying
for the pie of Rs.5.500 crore market. worldwide established brands , some of them
albeit new to India, like Shell ,Mobile ,Caltex ,Pennzoil are fighting it out with
established Indian brands like SERVO,MAK GE,CASTROL and others to
establish their foothold in the 6th largest lubricant market in the world. Compared
to the average world consumption of 35 million tons per annum & Asian pacific
region consumption of 7.5 million tones, the Indian lube industry with annul
demand of I million tone is just behind Japan and China in Asia having a demand
growth of 4% as compared to world growth rate ranging from zero to 2%.That is
the lube industry in India today.
Prior to the 1992, the lube industry in India was controlled by the 4four major
Public oil companies in India namely Indian oil, HP, BPC& IBP and handful of
private companies like Gulf, Castrol, Tidewater & other .With the distribution &
canalization of base oil import being controlled by the Government of India, the
PSU Oil Companies controlled 90% of the market share. The decimalization of the
lube base oil imports in 1993 by the Govt. of India followed by reduction of import
duty on lube base oils from 85% to 30% and gradual scrapping of administered
pricing observed the announcement of almost a new lube venture every month
during 1994. Most of the new entrants formed associations with Indian companies
both in the Private & Public sectors. All these new entrants are targeting for a very
small share of the market considering that even 1% market share means a sale of
Rs.55 Crores.
The Government policy of deregulation followed by entry of multinationals
through JVCs had its impact on the market dominance of PCUs. This had been
followed by entry of lot many players, each claiming to have some international
collaboration and a ‘foreign’ brand name. This had its initial impact and illusions
in the market and the market became more volatile. During these phases marketing
channels of distribution had drifted from petrol stations to bazaar trade.
The Marketing Channels
The marketing channels for automotive lubricants in India consist of the following,
Petrol Stations
Wholesale Distributors
Lube Oil Shops
Auto Spare Shops
Authorized Service Stations
Garages
Rural & Agricultural dealers
Super Markets.
Till recently, the Indian consumers linked filling of lubricants to that of petrol
& diesel in petrol stations. With the advent of deregulated market scenario & fierce
competition, efforts are being made to position lubricant as high involvement
consumer goods. Hence, the resultant drift towards the bazaar trade i.e., outside the
petrol stations. The sales of automotive lubricants through bazaar trade increased
from a mere 10% prior to 1993 to a handsome present level of 40% compared to
Worldwide Trend of more than 70%.In the developed World, because of high
degree of customer sensitivity & awareness, D0-it-Yourself (DIY) concept has
evolved for filling of engine oil. People buy from super markets & fill it
themselves. In India, this job is still left to the mechanics & service stations.
During these years this shift in trade had the following effects:
Decline in Market Share of PSU oil companies.
Market became heavily crowded & the industry got transformed into FMCG.
Dumping of products in the bazaar.
War of trade discounts resulting in rice war & lesser margins for dealers.
Entry of spurious lubricants.
Lubricant Industry Segmentation
The lubricant industry can be divided into two major categories i.e.,
Automotive & Industrial brand of lubricants. The industrial segment basically
comprises of Core Sector industries like Defense, Railways, State Transport
Undertakings, Steel Plants, Coal Mines, Fertilizers, Power Houses and
Chemicals & Heavy Engineering Industries. In the industrial segment, the PSUs
could successfully maintain their stronghold due to the reasons that the
requirement is most end use specific, customer focused, productivity linked &
service oriented. Here, price, quality, performance track record, R&D
infrastructure for technology up gradation and product development for end use
specific application & after sales service play the most significant role &
FMCG techniques of promotion and creating illusions takes a back seat. Indian
Oil virtually dominated and continues to dominate this sector through their
proven track record of quality product and vast network of professionalized pre
sales & after sales services. But the automotive segment which accounts for
major share i.e., 67% of the lubricant market became soft target for new
entrants and here private sector players could immediately consolidate their
market share by adopting FMCG techniques. PSU oil companies in general and
IOC in particular initially restricted their channel of distribution through their
large infrastructure of marketing network i.e, petrol stations & distributor
network. The focus happened to be on ensuring quality & customer
accountability and restrict mushrooming of spurious trade in bazaar through the
marketing channels where some kind of control could be exercised by the
company. The major thrust put by Industry leader like Indian Oil at this
juncture was to promote brand visibility and creation of brand image through
endorsement, TV advertisements & image building at Retail sites.
Strategic Business Plan
The PSUs initially could not resist the onslaught of dumping in bazaar channels
and illusions created by FMCG practices but off late started regaining their lost
ground and to some extent restrict & arrest their decline from a level as high at
90% to 65%. In this front Indian Oil after emerging as India's largest commercial
organization and being the only company in the country to feature in the Fortune
Global 500 listing has adopted structured business plan approach to strike a
balance between conventional marketing channels (petrol stations)/distribution
network and parallel marketing channels (bazaar trade). The parallel marketing
channels chosen by the Company also adopted the path of brand image, customer
focus & customer accountability by way of putting up SERVO Premium Lube
Shops in the bazaar trade. The petrol stations are also simultaneously undergoing
major facelifts through implementation of the companies Vision-2000
modernization plan. By way of this modernization the customers will get the
opportunity to pick up all their convenience stores in the `Convenio' (departmental
store) put up at the petrol stations while filling up petrol, diesel & lubricants.
Strength of an Oil Company
Manufacturing of quality lubricants is guided by two important parameters i.e,
resourcing of consistent premium quality base oils and incorporation of cost &
performance effective additive technology which is privy to the oil company
and is an effective tool to establish superiority over competitors. In this area R
& D effort plays a significant role as it has to be end use specific, location
specific, environment specific & at the same time cost effective. Just bringing
in imported technology without any own & defined resource of quality inputs
like base oil may not be suitable for Indian road/market conditions. Today,
technology has become so demanding and requirement is so stringent that
leading institutes like API (American Petroleum Institute) gives performance
approval on the basis of identification & sourcing of base oils. Their approval is
on crude specific, Refinery specific & base oil specific considerations. Bringing
in base oils taking leverage of decimalization of imports & reduction of duty,
putting up blending plants at Tax holiday locations to remain in the cut throat
competition & dumping may or may not yield far reaching benefits. The need
of the hour is long term commitment and not sheer opportunism and with more
competition expected in the coming years, customers will also realize impact of
such focused approach.
The automotive lubricant trade is gradually becoming wiser today. The traders
now understand the benefits of stocking fast moving & familiar brands instead
of overcrowding the shelf space because there are very few companies in India,
who can make the entire range of automotive products available. It has also
been found by the trade that because of working capital constraints the new
entrants are increasing cash discounts resulting in price war and reduction of
dealer margins. For making all the products available at all times a company
would need to keep a high inventory commensurate with the sales volume for
which an additional working capital of at least 35% would be necessary.
Among the oil companies in India, established companies like IOC have good
financial resources, who can afford to keep such high inventories.
R&D efforts & pursuits for excellence
Technology was never in short supply in the field of lubricant market in India.
In fact it is at par with the latest standards, thanks to the import of technology
and the exceptional efforts made by companies like IOC in the field of Research
& Development of indigenous products meeting World standards. The biggest
& one of the best petroleum R&D in Asia accredited with ISO 9001 belongs to
IOC. This R&D has developed over 1500 formulations through their scientists
with state of the art technology and enjoys approval from competent bodies
both at National & International level. Through development of bio-degradable,
energy efficient & eco-friendly lubricants, Titanium complex grease, Indian
Oil's R&D won various laurels like prestigious DSIR award, NRDC award for
best invention, ICMA & FICCI award & UN-WIPO award. It has also got over
75 National & International patents including the US & Australia. Over the
years IOC's R&D has demonstrated its ability to develop World class lubricants
suiting Indian conditions.
Quality & continuous technology up gradation is one of the key attention area
in this competitive environment and here also IOC scored very high among all
Oil Companies in India having secured ISO 9002 & ISO 14002 accreditation
for all its refineries, lube blending plants & QC labs.
Conclusion :
Lubricant market, in the last 5 years has seen severest turmoil and this phase
will continue for a year or two and then it is likely to stabilize. It is difficult to
predict what path it will undertake but one this is sure & certain that oil
companies owning refineries i.e., proven source of premium quality base stocks
(an essential component for manufacture of quality lubricants), sound R&D set
up with innovative business plan, wide distribution network with some system
of control & accountability and wide infrastructure of professionalized technical
services will continue to survive.
CNG ENGINE OIL
AN UPCOMING INDUSTRY
Compressed Natural Gas (CNG) is a fossil fuel substitute for gasoline (petrol),
diesel, or propane fuel. Although its combustion does produce greenhouse gases, it
is a more environmentally clean alternative to those fuels, and it is much safer than
other fuels in the event of a spill (natural gas is lighter than air, and disperses
quickly when released). CNG may also be mixed with biogas, produced from
landfills or wastewater, which doesn't increase the concentration of carbon in the
atmosphere.
CNG is made by compressing natural gas (which is mainly composed of methane
[CH4]), to less than 1% of the volume it occupies at standard atmospheric pressure.
It is stored and distributed in hard containers at a pressure of 200–248 bar (2900–
3600 psi), usually in cylindrical or spherical shapes.
CNG is used in traditional gasoline internal combustion engine cars that have been
converted into bi-fuel vehicles (gasoline/CNG). Natural gas vehicles are
increasingly used the Asia-Pacific region, Latin America, Europe, and America
due to rising gasoline prices.[1] In response to high fuel prices and environmental
concerns, CNG is starting to be used also in tuk-tuks and pickup trucks, transit and
school buses, and trains.
CNG's volumetric energy density is estimated to be 42% of LNG's (because it is
not liquefied), and 25% of diesel's.[2]
Developments
Scientists are developing methods of storing methane in a new form known as
ANG (Absorbed Natural Gas) at 35 bar (500 psi, the pressure of gas in natural gas
pipelines) in various sponge like materials, such as activated carbon [6] and metal-
organic frameworks (MOFs).[7] The fuel is stored at similar or greater energy
density than CNG. The benefits are that vehicles can be refuelled from the natural
gas network without extra gas compression, the fuel tanks can be made of lighter,
weaker materials, and the tank designed to be much slimmer.
CNG cars
Worldwide, there were 11.2 million natural gas vehicles by 2009, led by Pakistan
with 2.4 million, Argentina (1.8 million), Iran (1.7 million), Brazil (1.6 million),
and India (725 thousand).[1] with the Asia-Pacific region leading with 5.7 million
NGVs, followed by Latin America with almost 4 million vehicles.[1]
CNG cars available in Europe are bi-fuel vehicles burning one fuel at a time. Their
engine is a standard gasoline internal combustion engine (ICE). This means that
they can indifferently run on either gasoline from a gasoline tank or CNG from a
separate cylinder in the trunk. The driver can select what fuel to burn by simply
flipping a switch on the dashboard.
Several manufacturers (Fiat, Opel(General Motors), Peugeot, Volkswagen, Toyota,
Honda and others) sell bi-fuel cars. In 2006, Fiat introduced the Siena Tetrafuel in
the Brazilian market, equipped with a 1.4L FIRE engine that runs on E100, E25
(Standard Brazilian Gasoline), Gasoline and CNG.
Any existing gasoline vehicle can be converted to a bi-fuel (gasoline/CNG)
vehicle. Authorized shops can do the retrofitting, this involves installing a CNG
cylinder in the trunk, installing the plumbing, installing a CNG injection system
and the electronics.
CNG Advantage
Due to the absence of any lead or benzene content in CNG, the lead fouling of
spark plugs is eliminated. CNG-powered vehicles have lower maintenance costs
when compared with other fuel-powered vehicles. CNG fuel systems are sealed,
which prevents any spill or evaporation losses. Another practical advantage
observed is the increased life of lubricating oils, as CNG does not contaminate and
dilute the crankcase oil. CNG mixes easily and evenly in air being a gaseous fuel.
CNG is less likely to auto-ignite on hot surfaces, since it has a high auto-ignition
temperature (540 °C) and a narrow range (5%-15%) of flammability.[8]
CNG produces significantly lesser emissions of pollutants like carbon dioxide
(CO2), hydrocarbons (UHC), carbon monoxide (CO), nitrogen oxides (NOx), sulfur
oxides (SOx) and particulate matter (PM), as compared to petrol . For example, an
engine running on petrol for 100kms emits 22,000 grams of CO2, while covering
the same distance on CNG emits only 16,275 grams of CO2. [CNG is essentially
methane, ie CH4 with a calorific value of 900 Kj/mol. This burns with Oxygen to
produce 1 mol of CO2 and 2 mol of H2O. By comparison, petrol can be regarded
as essentially Benzene or similar, C6H6 with a calorific value of about 3,300
Kj/mol and this burns to produce 6 mol of CO2 and 3 mol of H2O. From this it can
be seen that per mol of CO2 produced, CNG releases over 1.6 times as much
energy as that released from petrol (or for the same amount of energy, CNG
produces nearly 40% less CO2).] The corresponding figures are 78 and 25.8 grams
respectively, for nitrogen oxides. Carbon monoxide emissions are reduced even
further. Due to lower carbon dioxide and nitrogen oxides emissions, switching to
CNG can help mitigate greenhouse gas emissions.[8] The ability of CNG to reduce
greenhouse gas emissions over the entire fuel lifecycle will depend on the source
of the natural gas and the fuel it is replacing. The lifecycle greenhouse gas
emissions for CNG compressed from California's pipeline natural gas is given a
value of 67.70 grams of CO2-equivalent per megajoule (gCO2e/MJ) by the
California Air Resources Board (ARB), approximately 28% lower than the average
gasoline fuel in that market (95.86 gCO2e/MJ). CNG produced from landfill
biogas was found by ARB to have the lowest greenhouse gas emissions of any fuel
analyzed, with a value of 11.26 gCO2e/MJ (over 88% lower than conventional
gasoline) in the low-carbon fuel standard that went into effect on January 12, 2010.[9]
CNG Locomotives
CNG Locomotives are operated by several railroads. The Napa Valley Wine Train
successfully retrofit a diesel locomotive to run on compressed natural gas before
2002.[10] This converted locomotive was upgraded to utilize a computer controlled
fuel injection system in May 2008, and is now the Napa Valley Wine Train's
primary locomotive[11] Ferrocarril Central Andino in Peru, has run a CNG
Locomotive on a freight line since 2005[12]. . CNG locomotives are usually diesel
locomotives that have been converted to use compressed natural gas generators
instead of diesel generators to generate the electricity that drives the motors of the
train. Some CNG locomotives are able to fire their cylinders only when there is a
demand for power, which, theoretically, gives them higher fuel efficiency than
conventional diesel engines.

INTRODUCTION
TOPIC
“TO ASSESS THE MARKET POTENTIAL OF CNG ENGINE OIL IN
LUCKNOW”.
RESEARCH PROBLEM
The poor sales of Gulf CNG supreme in CNG Engine Oil market is a
serious problem. In order to come up with the recommendations to
improve the sales, the following research was conducted.
NEED FOR THE RESEARCH
Though Gulf oil Corporation Limited is performing tremendously in the northern
region with increasing sales and expanding market share but the CNG engine oil is
not providing good business in the market.
In spite of the ample scope in the CNG Engine Oil market, the Gulf CNG Supreme
20W50, which is Premium Gas engine oil is not able to attract customers for itself.
Therefore, this static business provided the base and the need for the research work
to be done to resolve this serious problem.
OBJECTIVE
# To estimate the market potential and hence the business scope of CNG engine
oil.
# To understand the mindset of the customers about the positioning of different
engine oils in respect to their performance, price and schemes.
# Since Mechanics play the persuading factor in purchasing of engine oils
therefore it is necessary to understand the buying behavior of the mechanic and
how different marketing schemes persuade them.
# A great emphasis was also laid on the perceived quality of different engine oils
by different retailers and dealers in Lucknow , also the market share of engine oil
is calculated on from the information collected by the retailers and dealers.
JOB ASSIGNED
# To understand the working of the lube industry as a whole.
# to know the working of Distribution channel in the Lube sectors Gulf oil
Corporation Limited.
#to have the basic knowledge of the different products and product line,
manufactured by the gulf oil Corporation Limited.
#to understand the conditions and the competition which exist in the market and
the reasons for it.
# On the basis of these I was asked to prepare separate questionnaire for Retailers
and Dealers, Mechanic and Customers in order to understand their buying
behavior.
# the most important job was to visit the market and get the questionnaire filled up,
which covered the major part of my research work.
# and the data thus obtained was used for interpretation of the present situation of
the market and providing the recommendations to solve the research problem.
RESPONSIBILITIES
Through the research conducted by me,
I was asked to report:
1. The Market Potential of CNG Engine Oil.
2. The market share of each of the competitors.
3. Competition on all four P’s of marketing.
4. Population of CNG driven vehicle on road in Lucknow.
5. Number of counter stocking CNG Engine Oil.
6. Number of counters presently stocking Gulf CNG Supreme in Lucknow.
7. Number of Mechanic Garages specialized in CNG Engine Repairs.
8. Recommendation for increasing Gulf CNG Sales in the area with the
recommended strategy.
STAGES OF THE PROJECT
The whole Project was done on altogether 3 stages:
1. Initially, the lube industry was understood, it’s working and key factors
involved in it.
With the help of these learning, three questionnaires were prepared each for
Retailers and Dealers, Mechanics and Customers.
This stage took almost 12 days of the internship.
2. Then, the second stage was primary research where these questionnaires
were being filled by the technique of interview and hence the data was
collected. This stage took almost 5 weeks.
3. Finally, these data were observed and studied carefully and hence the
market potential, market share and other required information were
evaluated.
ACTIVITY SHEETS
1. Mid-evaluation sheet was being filled after the completion of
primary research.
2. Final evaluation sheet was being filled when the Report was finally
being submitted to the mentor.
RESEARCH
SCOPE OF THE RESEARCH
The research work is covering the whole Lucknow city. The respondents
includes Retailers , Dealers , Mechanics and Customers from the areas such as
Sardari Khera market, Kanpur Road, Lalbagh , Latus Road, Sitapur Road ,
Faizabad Road (HL hub Automarket) ,Chinnat and Kapurthala.
RESEARCH METHODOLOGY
This research was conducted to formulate the total market potential of CNG
engine Oil in Lucknow altogether and the market share of each of the Competitors.
And then analyzing the data to formulate the recommendation to increase the
sales of Gulf CNG Supreme.
TYPES OF RESEARCH
The nature of Research work conducted is Descriptive, as major part constitutes
survey analysis. The following research work is used in estimating the monthly
sales of different Engine Oil in a month.
Some part of the research is Exploratory as well. Some secondary data is also
used in order to know the number of vehicles using CNG engine.
SOURCES OF DATA COLLECTION
Primary Data: It was collected by interviewing the respondents in hindi .
Secondary Data: For collecting the secondary data, RTO office was consulted.
The information about number of CNG vehicles on road of last year was given
by Ashok Leyland service station.
SAMPLING TECHNIQUE
Judgmental or purposive sampling was used for the purpose. This is because the
primary consideration in purposive sampling is the judgment of the researcher as to
who can provide the best information to achieve the objective of the study.
During the research those respondent were only selected who are in researcher’s
opinion are likely to have the required information and willing to share it.
SAMPLE SIZE
The three questionnaires were filled up by different respondent during the
primary research.
Dealers and retailers : 50 sample
No. of Mechanics being interviewed : 40 sample
No. of customers (auto driver & bus driver) being interviewed : 40 sample
LIMITATIONS OF THE RESEARCH
The primary as well as secondary research was conducted by one person, so
there can be some human error during the analysis of data.
It was really a challenge to get the information about their sale and margin they
get.

MARKET SIZE ESTIMATION
THROUGH PRIMARY DATA
The monthly sales of each of the Retailers and Dealers were summed up to get
the market size of the CNG Engine Oil as a whole.
According to the Survey analysis and the Data collected the percentage
of Dealers and Retailers covered were 80% of the whole present in
Lucknow.
We have,
MS = ∑ ms
Where, MS – Market Size
ms- Monthly Sales.
From the primary data collected, the monthly sales of the Lucknow
region (only the counters which were consulted during the research) is
29754ltrs or 30 kltrs (approximately).
Since the survey covered only 80% (approximately) of the total Lucknow
CNG engine Oil sales,
Therefore, the actual Market Size be ‘x’.
80% of x = 29754
i.e. x=37.192.5ltrs
Thus Market size of Lucknow in CNG Engine Oil industry is 37kltrs, which
means lots of scope for the business to expand.
MARKET SIZE ESTIMATION
THROUGH SECONDARY DATA
According to the Data collected:
“ From the Lucknow RTO office (Faizabad road):
DATA TILL 2008: CNG vehicles on road.
Number OF Three Wheelers:
Number of Autos – 5015
Number of Vikrams– 3776
#Total number of three wheelers = 8791
DATA FOR 2009-10 TILL MARCH (CNG vehicles on road)
Obtained from Service station of Ashok Leyland: (Faizabad road)
Number of Three wheelers – 1550
Number of buses -27
Again,
Rate of consumption of engine oil by three wheeler = 2ltrs
monthly per vehicle
Rate of consumption of engine oil by buses = 15ltrs per
20000kms = i.e. 15ltrs per 4 months
= 3.75ltrs per month
Therefore, Engine oil consumption by three wheelers = (8791+1550) ×2
=20682ltrs
Engine Oil consumption by buses = (109+27) × 3.75
=510ltrs
Hence, total Engine oil consumption = 21192ltrs
= 21kltrs.
MARKET SHARE ESTIMATION
During the survey the sales of individual brands were also recorded in order to
calculate the Market Share of individual brands.

OBSERVATIONS:
The Public Sector enjoys the largest share in the CNG Engine Oil market
with 70% shares whereas Private sector could only capture 30% of the
total market share.
CONCLUSION:
The Taxation Policy of the Government and the Distribution Network ,
basically the Petrol pumps add to the low Price and the Availability of
the products of the Public Sector , which is the reason behind their high
market share.
Therefore, the benefits enjoyed by the Public sectors are
1. Rebate in taxation on the base oils.
2. Hence, the low price of the Public owned products.
3. Their own Petrol Pumps which acts as a retail outlets for their
Engine Oils.

The pie chart showing competition within the Private sector.
OBSERVATION:
In the Private sector, British Petroleum is covering 71% of the market share
alone.
The Castrol GTX is the best Quality Premium oil and people are going for it
though it is charging the most.
Castrol BP has low price and its perceived Quality is satisfactory.
Pennzoil is the next one who has captured the market with its uniqueness.
Others include Veedol , Valvoline, Gulf OIL and Motul which are not
performing well . They together could capture only the market share of 10%
of the Private market share, which shows their weakness in one aspect or the
other.
CONCLUSION:
Though Price is an important factor determining the buying behavior of the
customers in this segment but still Quality is something which ban never be
ignored.
One can never do well only by lowering the price of the product, the
positioning of the product is equally important.
Promotional activity is need of the time for a brand in order to register itself
in the mind of the customers.

Chart showing the relationship between Price and Market Shares.
OBSERVATION:
Through the chart it can be observed that there is no relationship between
the price and the market shares of the Engine Oils. Both the factors are
independent of each other.
Price is just a parameter for customers to judge their affordability.
The most amazing fact is that though Castrol is costly Product but it has
got high market share, i.e. there are still customers who are ready to pay
the high price for a premium product whose performance and Quality is
perceived to be the best.
CONCLUSION:
From the available data and the Research conducted it can be concluded
that in a price sensitive market also Quality cannot be compromised.
The performance is been Judged by the perceived value of the particular
brand upon the mind of the customers.
Therefore, the biggest task is to increase the perceived value of a
particular brand through different promotional activities and the market
share would automatically increase.
RETAILERS AND DEALERS PERSEPTION ABOUT THE
PERFORMANCE:
In the third question of the questionnaire, the Retailers and dealers had to rank

are low in price but best in quality. This is because they are the one who actually

78% of the Mechanics prefer MAK GE.
Other brands being preferred is Servo & Castrol GTX.

which is attracting so many mechanics towards them and inspires them to
increase their sales.

Factors contributing in the popularity of MAK GE
MECHANIC’S VIEW
The mechanics are those people who do all the servicing of engine oil in auto
vehicles and generally recommends auto driver to use a particular brand. The
major factor which is effecting the selection of a particular brand of oil is that of
mechanic satisfaction.
From the Data obtained, it is clear that 90% of the auto drivers are
uneducated and unaware about the quality standard of engine oil. So, it is
by the word of mechanic and recommendations they adopt the general
perception about a particular brand. Therefore, a company should work
towards developing a positive brand image in the mind of mechanics
through various campaign and meets.
Asking recommendations from mechanics will make them feel important
and hence will help in the promotion of the brand, via word of mouth to
the customers.
Gulf Oil Corporation Limited have been organizing mechanic meets over
a period of time if same is done for Auto mechanics, they will feel
themselves as the part of the company and would definitely bring in some
more business.

SOME IMPORTANT FACTS FOUND
There are 120 counters (approximately) in the the Lucknow stocking
CNG Engine Oil.
Out of the total counters, 40% of the counters i.e. only 48 counter
(approximately) tocks CNG Engine Oil.
Number of mechanic garages specialized in CNG engine repairs is
approximately 1500.(including big and small service stations.
In Lucknow, still the trucks being used are diesel driven and not CNG
driven.
And therefore, Trucks were not considered in the segment of CNG driven
vehicle.
Also, truck driver was not consulted for the primary research.
RECOMMENDATIONS
RECOMMENDATIONS FOR INCREASE IN SALES
Gulf CNG Supreme 20W-50 has positioned itself as a premium brand in the
market. Its performance and quality are good according to the experts but still it is
not able to make any mark in the market and performing badly with the market
share of 2% in the the Private sector. The research work hence done suggests some
of the measures to be implemented to increase the sales and thus the market share
of the Gulf CNG supreme.
An important fact is that according to the research survey only 5% of the
mechanics have tried the product.
But the best part is all those who have tried it are completely satisfied
with its quality and performance.
THE 4 P’S OF MARKETING:
PRODUCT:
The product is completely acceptable on the parameters of the
customer’s choice.
The quality and the packaging Gulf CNG supreme is good and
there is no need of any change in the Product.
PLACE:
Gulf CNG Supreme is available in the 40% of the counters, reason
being it is less in demand.
Once the demand for the product is generated, the availability will
automatically increase.
And therefore, making the product available is not a problem.
PRICE:
Price plays a major factor in the buying decisions of the customers.
Also the MAK GE has captured a major part in the market by
playing the trump of the low price factor.
Before demanding the high price .The Gulf oil should position
itself in such a way that its price value should look fully justified.
For ex. Castrol GTX charges high rate and boost itself as the best
in the market and even consumer don’t mind paying such a high
price. Therefore, proper positioning of the product is important to
target the mass market.
Hence, initially Gulf oil should go lowering the price for a short
duration which can make it affordable for the masses and hence
provide them a scope to judge the oil. Once, the try it , they would
surely go for it.
PROMOTION:
The promotion for the Gulf CNG supreme is extremely poor. People
hardly know about this.
The lack of promotion is the basic reason for the failure of the brand in
the market.
Therefore, in order to increase the sales there is need of lots of
promotional activities in order to increase the perceived value of the
Gulf CNG Supreme.
The promotional activities can be done through mechanic meets, as
being conducted for other products of the company.
Radio advertisements, pamphlet distribution and road campaigning are
other activities which if introduced will surely bring the business.
