What about removing the oil fill cap when draining oil to help assist draining the old oil? I never heard of that until recently and now I do remove the cap. But does it really help at all?
I don't need to make changing oil a 2 day affair, I just drain the oil, carefully hand thread the plug back in then snug it down with a wrench, move the pan over to under the oil filter, remove and replace it, and then lower car and add fresh oil. Start up, check for pressure and leaks, then reset the change oil dash light if so equipped, and off I go.
I change my oil and filter at recommended intervals and after 40 years of owning cars and changing my own oil I've never had an engine problem or oil burner (knock wood).
