4.3.1Oil Specifications

Use oil that displays the American Petroleum Institute (API) Starburst certification mark FOR GASOLINE ENGINES on the container. Do not use straight-weight oils recommended for industrial or stationary engines.

CCor CD classification oils, even when labeled Heavy Duty or For Natural Gas Engines are not acceptable.

Multi-viscosity oils are recommended. Figure 4-1 shows the recommended Society of Automotive Engineers (SAE) viscosity designation for a given operating temperature.

4.3.2Oil Check

Check the oil level in the crankcase every 24 hours of operation or before the engine is started each day. Do not check the oil level while operating the unit. Stop the generator set and keep the generator set level to get an accurate reading. To check the oil level, remove the dipstick and wipe the end clean. Reinsert the dipstick and wait at least 30 seconds. Remove the dipstick and check the level. Maintain the oil level between the Full and Add marks on the dipstick, as shown in Figure 4-2. See Section 1, Service Views for the dipstick location.

Note: Do not operate the set if the oil level is below the Add mark or above the Full mark on the dipstick.

4.3.3Oil Additions

Adding some oil between oil changes is normal. The amount varies with generator set usage. Open the oil fill cap and pour in a small amount of oil using a funnel or other suitable pouring device. See Section 1, Service Views, for the oil check and oil fill locations.

4.3.4Oil and Filter Change

Change the oil according to the service schedule or before generator set storage. Change the oil more frequently if the generator set operates under dirty, dusty conditions. Change the oil while the engine is still warm. See Section 1, Service Views, for oil fill, oil check, and oil filter locations.

Dispose of all waste materials (engine oil, fuel, filter, etc.) in an environmentally safe manner.

Note: Reset the maintenance timer on the RDC2 controller after changing the oil.
