Engine Oil (Gasoline Engine)
If your vehicle has a diesel engine, see "Engine Oil
(Diesel Engine)" in the Diesel Engine Supplement.
It's a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
The engine oil dipstick has
a yellow handle and is
located near the center of
the engine compartment.
Turn off the engine and
give the oil a few minutes
to drain back into the oil
pan. If you don't, the oil
dipstick might not show
the actual level.
