27.2 Engine Oil
The petroleum oils recommended for use in this refrigeration unit must
comply with the American Petroleum Institute's (API) Class CG or better
rating. The only recommended synthetic oil is Mobil Delvac 1. The use of any
oil that does not meet this rating may affect the warranty on the engine. The
use of oil of the proper weight (viscosity) is also essential.
The following chart indicates recommended engine oil for various climates:
27.3 Checking Engine Oil Level
1. Run the unit to bring the engine up to operating temperature
2. Shut the unit off, and remove the cap/dipstick.
3. Wipe the dipstick clean and insert it into the oil fill tube without threading it
all the way back into the tube.
4. Remove the dipstick again and check oil level. DO NOT add oil if the level
is in the “safe” range. If needed, add oil as indicated by markings on
dipstick until level is in the “safe” range.
