I don't suppose that quart of old oil remaining in the pan will cause any problems. I'm not sure what dropping the "belly pan" entails but it sounds like a lot more effort than my limited experience allows. Would a garage mechanic drop the pan or just use the vacuum method?
Several use the extractor, me I always drop the pan and drain it, 4 screws hold mine on.
I have used a extractor to take out oil after a shop put in to much oil.
If I paid a shop / garage to change my oil and they extracted it instead of drainingit, I would be royally PO.....
I have had 3 times at 3 different shops and might have been in 2 different states other than my own that lost the screws to the belly pan and threw the belly pan to the side and was not going to put it back on, and had my car down and backed out and ready to go.
Till I asked about the belly pan still sitting on the floor.
Leaving 1 quart of oil in seems like alot. Maybe angle your car was at or the tube curled up some etc.
Do you have even a spot in your yard that is angled to just drive on and have the backend of your car higher to let more oil poll to the front, might get alittle more oil out.
I bet someone who uses extractor often will chim in how they do it.
