A cold oil check is unreliable. If possible,
check oil within 10 minutes after engine
shutdown. If over 10 minutes have
elapsed, motor the engine (starter only) for
15-20 seconds, then recheck. If over 10
hours have elapsed, start the engine and
run for 2 minutes, then recheck. Add oil
as required. Do not overfill.
Remove oil filler cap.
Insert a clean funnel, with a screen
incorporated, into the filler neck.
Replenish with oil to within 1 quart
below MAX mark or the MAX COLD
on dipstick (cold engine). Fill to
MAX or MAX HOT (hot engine).
Check oil filler cap for damaged
condition and locking.
Insure that oil filler cap is correctly
installed and securely locked to prevent
loss of oil and possible engine failure.
If oil level is over 2 quarts low,
motor or run engine as required,
and service as necessary.
Install and secure oil filler cap.
