Fuel ConsumptionBy: Vassilis Perdikoulis

Fun Facts

Petrol- “The first automotive combustion

engines, so-called Otto engines, were developed in the last quarter of the 19th century in Germany.”

Diesel- “In Europe, the United States, and

Canada, taxes on diesel fuel are higher than on heating oil due to the fuel tax.”

Pros and Cons of Petrol Cars

Pros:- Fast acceleration.- Easier to handle. Cons- More funds are needed for fuel.

Pros and Cons of Diesel Cars

Pros:- Less funds are needed for fuel.- Longer durability Cons- The car is more expensive in

maintenance. - It pollutes more.- Slow acceleration.

Calculation 1: Petrol Car(Nissan Pathfinder 1998)

Every day my family uses: 6 L- The price of each L is 47 MZN.- The total price is: 6×47= 282 MZN Every week my family uses: 6×7= 42 L- The total price is: 42×47=1,974 MZN Every 31 day month my family uses: 6×31=186 L- The total price is: 186×47= 8,742 MZN Every 365 day year my family uses: 6×365=2,190

L-The total price is: 2,190×47=102930

Calculation 2: Diesel Car(Land rover discovery 1998)

Every day my family uses: 4 L- The price of each L is: 47- The total price is: 47×4= 180 MZN Every week my family uses: 4×7= 28 L- The total price is: 28×47=1,316 MZN Every 31 day month my family uses: 4×31=124 L- The total price is: 124×47= 5,828 MZN Every 365 day year my family uses:

4×365=1,460 L-The total price is: 1,460×47=68,620

Environmental Aspects

As my calculations have proven, I think it is better to use a diesel Car instead of a petrol one.

Newer generation diesel engines are being made and improved , thus adding a new pro to the list.
