engine oil (i.e., drain the oil tank, add oil to the tank to the proper level -- do NOT rotate the prop
at any point during the oil and filter change procedure).
f. Start the engine and check for proper oil pressure. Check for oil leaks after warming up the
engine. Check for proper oil level in the oil tank, and add oil if necessary.
g. Again check for oil leakage after the engine has been run at a high power setting (preferably
following a flight around the field).
