Engine Oil: Testing and Inspection
CHECKING ENGINE OIL1. Position the vehicle on a level surface.
2. Warm up the engine.
NOTE: If the vehicle has been out of service for a prolonged period of time, warm up the engine for approximately 20 minutes.
3. Turn off the engine, and wait 2 or 3 minutes, then check the oil level.
4. 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 "L" mark), refill to the "F" mark.
NOTE: When refilling, use the same type of engine oil.
5. Check that the oil is not dirty or contaminated with coolant or gasoline, and that it has the proper viscosity.
SELECTION OF ENGINE OIL
Recommended API classification: SD OR ABOVE SE OR ABOVE [For EC.]
Recommended SAE viscosity grades
NOTE:
For best performance and maximum protection of all types of operation, select only those lubricants which:
1. Satisfy the requirements of the API classification.
2. Have proper SAE grade number for expected ambient temperature range.
Lubricants that do not have both an SAE grade number and an API service classification on the container should not be used.
