The subject pretty much says it all. I would think that if you drive a vehicle and get the oil nice and hot, then immediately drain it and remove the filter, that most of the oil would end up in the collection container...except for maybe a film of oil on internal parts.
Is this true, or does an engine retain a significant amount of oil...I've heard as much as a half to 1 qt remains. (I have never actually measured the amount of oil coming out.)
In this case, wouldn't it make sense to run a cleaner just before draining?
