Engine Oil: Testing and Inspection

CHECKING ENGINE OIL
1. Position vehicle on a level surface.
2. Stop 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 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.
