7.1 Park the vehicle on a level surface. Allow
several minutes for the oil to drain back
into the oil pan to ensure an accurate
reading.
NOTE: For diesel engines, follow the engine
manufacturer's guidelines for engine shut-
down time requirements prior to checking
the oil level.
7.2 Pull out the dipstick and clean it with a
paper towel or cloth, then push the dip-
stick back in all the way. Remove it again,
keeping the tip down, and check the oil
level.
7.3 If the oil is below the cross-hatched area,
or the add mark, at the tip of the dipstick,
add at least one quart (liter) of the recom-
mended oil. See
for diesel engines, and
pane engines.
For diesel engines that comply with
EPA07 or newer regulations, use CJ-4
engine oil with less than 1% sulfated ash.
For liquid propane gas (LPG) engines, use
SAE 5W–30 oil that meets GM standard
GM6094M and has the American Petro-
leum Institute (API) symbol. Do not use
SAE 10W–40 or 20W–50.
