Engine Oil

NOTICE
Use engine oil that is identified as meeting GM
standard GM6094M and showing the American
Petroleum Institute (API) starburst symbol. Fail-
ure to use the recommended oil can result in en-
gine damage and will void the engine warranty.
When determining the type of engine oil to use, look
for three things.
•
Use only an oil that meets GM standard
GM6094M.
•
Oil grade SAE 5W–30 is best for the engine.
Do not use SAE 10W–40 or 20W–50.
•
The API starburst symbol. See

Fig. 15.4, API Symbol
If the vehicle is being operated in an area of extreme
cold, the use of SAE 5W–30 oil will provide easier
cold starting for the engine.
Engine Oil Additives
Do not add anything to the oil. The recommended
oils with the API starburst symbol that meet GM stan-
dard GM6094M are all that is needed for good per-
formance and engine protection.
Engine Oil Flushing
NOTICE
Engine oil system flushing is not recommended
and could cause engine damage not covered by
the engine warranty.

Checking the Engine Oil
It is important to check the oil regularly and keep it at
the proper level. In order to get an accurate reading,
the oil must be warm and the vehicle must be on
level ground.

Changing the Engine Oil
The engine oil must be changed every 3000 miles
(4827 km). See maintenance operation 01–03 in the
Walk-In Van Chassis Maintenance Manual for de-
tailed instructions.

Ametek Instrument Panel

The following information describes the Ametek in-
strument panel, used with gasoline engines. The in-
strument panel is shown in
NOTE: The instrument panel is shown with a
standard U.S. speedometer, which shows miles
per hour (mph) more prominently than kilome-
ters per hour (km/h).
Turn off the engine and give the oil several min-
utes to drain back into the oil pan. If this is not
done, the oil dipstick may not show the actual
level.
Pull out the dipstick and clean it with a paper
towel or cloth, then push the dipstick back in all
the way. Remove it again, keeping the tip down,
and check the level.
If the oil is below the cross-hatched area at the
tip of the dipstick, add at least one quart (liter) of
the recommended oil. See
