I have tried multiple oil extractors over the years - most work well except I never had much luck with the pumps attached to a hand power drill. I have changed oil a couple times a season for decades and like the simplicity of the hand pumps that create a vacuum in a canister and draw the warm oil out of the dipstick opening.- takes about 15 -20 min for my 4 qts. There are multiple brands out there. The small 12 volt pumps work well as long as they are primed.
