Engine Oil: Testing and Inspection

CHECKING ENGINE OIL
1. Position a vehicle on a level surface.
2. Turn off the engine.

NOTE: if a vehicle that has not been used for a prolonged period, run the engine for several minutes.
Turn off the engine and wait for 5 minutes at least, and 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 "L" mark), refill to the "F" mark.

NOTE: When refilling, use the proper grade of engine oil.





4. Check that the oil is not dirty or mixed with coolant or gasoline and it has the proper viscosity.
