Engine Oil: Testing and Inspection
CHECKING ENGINE OIL1. Position a vehicle on a level surface.
2. Stop the engine.
NOTE: In the case of a vehicle that has been out of service for a prolonged period, run the engine for several minutes. Stop the engine and wait for 5 minutes at least, then check the oil level.
3. Check that the engine oil level is within the level range indicated on the oil dipstick. If the oil level is found to have fallen to the lower limit (the MIN mark), refill to the "MAX" mark.
NOTE: When refilling, use the same type of engine oil as the one currently being used.
4. Check that the oil is not dirty or mixed with coolant or gasoline, and that it has the proper viscosity.
SELECTION OF ENGINE OIL
Recommended API classification: SG or SG/CD, SH or SH/CD
Recommended SAE viscosity grades
NOTE:
For best performance and for maximum protection for all types of operation, select only those lubricants which:
1 Confirm the requirements of the API classification.
2 Have proper SAE grade number for expected ambient temperature range. Lubricants which do not have both a SAE grade number and an API service classification on the container should not be used.
