Oil Check

Use high quality detergent oil of API (American Petroleum Institute) service class SF, SF/CC, or SF/CD. This information can be found on most oil containers, see Figure 3-1. The symbol illustrated identifies the API service class in the upper portion. The center indicates the SAE (Society of Automotive Engineers) viscosity grade. The bottom portion (when used) signifies the oil is intended to improve fuel economy and displays the phrase “Energy Conserving.”Select viscosity based on the air temperature at the time of operation. (See Figure 3-2.)

SAE 10W40 is the preferred oil for general use where temperatures permit.

Viscosity Grades

Using other than the appropriate service class oil or extended oil change intervals could cause engine damage which is not covered by the engine warranty.

Do not mix oils of different viscosities. It is also best not to mix different brands of oils. Possible incompatibility could cause a breakdown of lubricating ingredients and reduce engine protection.

Check oil level in crankcase daily or before each startup to insure that the level is in the safe range.

NOTE

Do not check oil level when unit is running. Generator set must be stopped and level to get an accurate reading.

If generator set has just been run, allow a few minutes for the oil to return to the oil pan before checking level.

To check oil level, remove dipstick and wipe the end clean, place bottom thread of dipstick against oil fill hole and remove. Do not screw in dipstick when checking oil level. Level should be between MIN and MAX marks on dipstick. See Figure 3-3.

NOTE

Do not operate the set if the level is below the MIN mark or above the MAX mark. Oil above the MAX mark is wasted due to increased oil consumption.
