Checking Engine Oil

Position the vehicle on a level surface.
Warm up the engine.
NOTE: If a vehicle has been out of service for a prolonged period of time, warm up the engine for approximately 20 minutes.
Turn off the engine, and wait 2 or 3 minutes, then check the oil level.
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.
Check that the oil is not dirty or contaminated with coolant or gasoline, and that it has the proper viscosity.
