When you guys' refill your oil, do you get anywhere near 3.9 quarts back in? Today I did my second oil change on this engine and I ended up at a little less than 3.6 quarts (similar amount on the first oil change). I throughly warmed up the engine prior to this change, let it drain for over an hour, prefilled the filter (the amount is included in the 3.6 quarts), warmed and cooled the engine, and yet the dipstick reads "full." Can there be that much residual oil in a warm engine and pan? I thought that the 3.9 quart spec is for oil changes while there is a larger number for total engine capacity. BTW: I'm doing these oil changes on a level surface. Any similar experiences?
