Remove dipstick and check oil level and condition.
Is oil above "full" mark or below "add" mark on dipstick.
Does the oil look milky or grainy?
If oil level is high, check for fuel or anti-freeze. Drain a small amount of engine oil into
a clear container. Watch oil in container to see if anti-freeze or water accumulates at
the bottom. If oil is milky, moisture or anti-freeze may be present.
If oil is grainy, carbon may be present. Carbon in oil may result when engine runs at
slow idle too long.
If oil level is low, check for oil leaks or oil seal problems in engine.
Adjust oil level to between "add" and "full" marks on dipstick.
