When To Add Engine Oil; Checking Engine Oil - Buick 1999 Park Avenue Owner's Manual

Checking Engine Oil

Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it again,
keeping the tip down, and check the level.
Turn off the engine and
give the oil several minutes
to drain back into the oil
pan. If you don't, the oil
dipstick might not show
the actual level.

When to Add Engine Oil

If the oil is at or below the ADD mark, then you'll need
to add at least one quart of oil. But you must use the
right kind. This part explains what kind of oil to use. For
crankcase capacity, see "Capacities and Specifications"
in the Index.
