Maybe on a tiny sump? My euro cars that run nearly 2 gallons of HDEO take way too long, even when hot. Certainly more than ten pumps!I have found it is so fast to stab the tube, pump it 10 times and let it extract. After it sucks a little air, I fish around with the tube to get a more complete extract. Pull out the tube and expel into the recycle container. No mess, no jack, stands, drain pan, tools, very fast. I'm sold.
If I were doing a regular drain, I would let it drain at least as long as I extract.
I do pull the drain plug once in awhile if I am swapping the filter. But even then I use the extractor due to less mess, especially spills.
Jusy my experience and 2 cents.
