8A-13. FUEL SAMPLE AND OIL CHECK.
A cold oil check is unreliable. Oil should
be checked within 10 minutes after
stopping engine. If more than 10 minutes
40 seconds, then recheck. If more than
10 hours have elapsed, run engine for
2 minutes, then recheck. Add oil as
required. Do not overfill.
Fuel and oil quantity checks may be
performed prior to Exterior Check to
preclude carrying a ladder and fuel sample
container during the balance of the
preflight. During warm weather, open fuel
caps slowly to prevent being sprayed by
fuel under pressure.
