I have been ?burping? the engine before the first flight each day and then checking oil level prior to starting the engine. TT is 77 hours with almost 30 hours since oil change. Engine is not using any oil as checked per above procedure.
Today I decided to check oil level at the end of the flight and was surprised to find oil level in the sump tank to be below the end of the dipstick and completely out of range of the flat marking on the stick. I thought the oil tank would have held the entire quantity of oil for some period of time before slowly bleeding back through the oil pump and into the crankcase.
Am I over-thinking this or is it normal to not have a full oil tank at the end of a flight?
