GE Proprietary and Confidential Information 1

1. GENERAL INFORMATION

This publication provides information on the recommended fuels and oils that are approved for use in General Elec-tric V228 and L/V250 marine and stationary diesel engine applications.

2. DIESEL ENGINE OILS

2.1. HEAVY-DUTY ENGINE OILS

The GE V228 and L/V250 diesel engines require a heavy-duty, highly dispersant SAE 40 or SAE 20W40 lubricating oil.The minimum new-oil kinematic viscosity for SAE 40 oils is 13.9 cSt at 100oC (75 SSU at 210oF) with a viscosity indexrange of 65 to 105. The minimum absolute viscosity for SAE 20W40 oils is 10.8 centiPoise at 100oC with a viscosityindex range of 108 to 125.

Lubricating oils used in the GE V228 and L/V250 diesel engines must meet General Electrics approval criteria whichis based on demonstrated performance. Approval letters issued by General Electric are given to the companies whomarket engine oils to the users of GE V228 and L/V250 diesel engines. Customers should contact General Electric forrecommendations and a list of GE-approved Generation 4 Long Life Engine oils.

2.2. MIXTURE OF ENGINE OILS

All engine oils on the General Electric Approved Lists, for use in GE V228 and L/V250 diesel engines, are fully compat-ible, and may be mixed in any ratio without causing harm to the engine. However, for optimal performance and pre-vention of possible unforeseen incompatibility issues, GE recommends single source supply.

With engine lubricating oils, however, approval is made by brand and grade; thus compatibility is known. An oil is notapproved until found to be compatible with all others on the approved list. Approval consists of both factory andfield testing.

2.3. ENGINE OIL SELECTION BASED ON FUEL SULFUR

The importance of matching engine oil with fuel sulfur content can not be overstated. A severe reduction in enginelife can occur as a result of:

1. Sulfuric acid corrosion resulting from high sulfur fuels.

2. Carbon deposits in the combustion chamber resulting from high TBN oils used with low sulfur fuels.

Every bulk load of fuel must be analyzed for sulfur content. Sulfuric acid corrosion resulting from high sulfur fuels can be partially mitigated with high TBN oils. However, higher TBN oils contain higher levels of ash, which in the absence of high sulfur fuels results in carbon buildup and excessive power assembly component wear.

For ASTM D-975 2D S5000, GE recommends a minimum new-oil TBN of 10, or 20 times the fuel sulfur content (%),whichever is higher. For example, a 0.75% sulfur fuel would require a minimum lubricating oil TBN of 15 (0.75 x 20)and thus the next highest TBN commercially available lubricating oil would be used.

Each vessel operator must assess sulfur variability in their fuel sources, and select an oil TBN based on the highestsulfur content fuel source they are likely to encounter prior to their next oil change.

2.4. ENGINE OIL CONDEMNING LIMITS AND MEASUREMENTS

General Electric recommends frequent testing of lubricating oil for pentane insolubles, metal, viscosity, water con-tent and alkalinity reserve. These tests should be performed every 150 to 250 hours of engine operation.

Frequent testing will help detect fuel dilution and water contamination and avoid excessive deposits, corrosion oroxidized oil which could damage engine bearings and other components. Additional tests such as Infrared Spectramay be used to obtain other oil condition information (i.e., oxidation, sulfation, etc.). Elemental analysis may be usedfor trending any wear metals.

Engine oil condemning limits on viscosity and water contamination as well as alkalinity and insolubles are given inTable 1.

It is suggested that an advanced warning system (flagging technique) be used for monitoring oil trend analysisresults. If the oil trend analysis trend indicates the oil is approaching an oil condemning limit(s), a warning should bemade to ensure the engine does not operate beyond the oils useful life.

2.5. ENGINE OIL SAMPLING PROCEDURE

GE recommends that oil samples be collected for analysis every 150 to 250 hours of engine operation. Before begin-ning to take the sample, be sure to write all pertinent information on the sampling bottle. The preferred method ofcollecting an oil sample is by using the oil sampling valve on the inlet pipe to the engine. The oil sample should betaken while the engine is at idle. Clean the sample valve and purge it by allowing approximately 2 to 3 ounces of oilto flow out, prior to taking the sample.

NOTE: If it is necessary to collect the sample when the engine is shutdown, the oil sample should be collectedwithin 15 minutes after shutting down the engine.

The oil sample bottle should be filled between 2/3 to 3/4 full.

NOTE: If samples are to be taken from multiple engines, ensure there is no cross-contamination of oil samples bycleaning the sampling equipment between taking samples.

2.6. ENGINE OIL LIFE

In addition to frequent oil sampling and trend analysis, General Electric recommends that the engine oil be drainedafter a period of operating hours. Table 2 shows the recommended oil change intervals for different engine dutycycles. Draining and refilling with new oil at these limit intervals, even though the used oil has not reached the con-demning limits in Table 1, will ensure that the additive package is able to maintain cleanliness and durability of theengine.

NOTE: The best measure of average fuel consumption is the total fuel consumed divided by the engine operatinghours. For example, if a 16V228 engine consumed 55200 liters of fuel over 1450 hours of operation, the averagefuel consumption would be 23.8 liters/hour per cylinder, making it a medium duty cycle application. The aver-age fuel consumption should be measured over a period of time sufficient to represent typical service conditionsfor the application.

If the environment is excessively hot (sustained operation over 90oF) or airborne dust and dirt are prevalent, morefrequent oil changes than those in Table 2 are recommended.

When engine oil change intervals are overextended, severe engine problems may result which would affect enginecomponent durability and increase unscheduled maintenance. Precautions should be taken to regularly inspect forexcessive deposits on the internal engine components to ensure the oil has not gone beyond its useful life.

2.7. ENGINE OIL CHANGEOUT PROCEDURE

Engine oil changes should include the following:

1. Draining engine oil (recommend oil drain when engine is hot).

2. Removing lubricating oil filters (if applicable).

3. Cleaning the oil filter housing (if applicable).

4. Installing new filters (if applicable).

5. Refill with approved engine oil.

3. FUEL SPECIFICATIONS

3.1. FUEL OILS

The GE V228 and L/V250 Marine and Stationary diesel engines are capable of operation on the following fuel. Referto the published standard regarding the exact specifications for this fuel category:

ASTM D-975 Number 2 Diesel (2D) S15, S500, and S5000: ASTM D-975 is the recommended fuel for GE dieselengines. It meets the requirements of the American Society for Testing and Materials (ASTM) Specification D-975for Number 2 Diesel (N2D) fuel.

ISO 8217 DMX: This fuel is similar to ASTM D975 Number 2 Diesel, but with a maximum of 1% allowable sulfurcontent and a wider range for allowable kinematic viscosity.

ISO 8217 DMA: This fuel is similar to ISO 8217 DMX fuel, but with a maximum of 1.5% allowable sulfur contentand a wider range for kinematic viscosity. Increased engine maintenance may be required when using DMA fuelwhen compared to using higher quality fuels. DMA fuel is not recommended for use in GE diesel engines.

ISO 8217 DMZ: This fuel is similar to ISO 8217 DMA fuel, but with a minimum kinematic viscosity at 40oC of 3.000mm2/s. DMZ fuel is not recommended to for use in GE diesel engines.

ISO 8217 DMB: This is the lowest quality fuel allowable for use in GE V228 and L/V250Marine and Stationary die-sel engines. Increased engine maintenance will be required when using DMB fuel when compared to usinghigher quality fuels. DMB fuel is not recommended for use in GE diesel engines.

NATO F75/76: This fuel is similar to ASTM D975 Number 2 Diesel, but with a higher 90% distillation point.Increased engine maintenance may be required when using F75/76 compared to higher quality fuels.

Other international or organizational fuel specifications (i.e., GOST, EN, Australian fuel specifications) may be applica-ble, to the extent that those specifications describe fuel that is the equivalent of ASTM D-975. Samples of such fuelshall be evaluated and approved by General Electric prior to use.
