Leading question, and putting words into my mouth. I never said I quickly put the drain plug in. Direct answer? Yes, simply waiting for the majority of the oil to drain and quickly screwing the drain plug in will leave crap in your engine. I said your method was not necessary, and used my own experience over 30 years of my life, and 50 of my father's. We've never had an engine fail due to oil problems.
#2. Allowing engine oil to drain thoroughly does not help eliminate a good percentage of dirty oil and metallic particles?
Yes, draining thoroughly works.
You stated NO reason...
I certainly did. It was my experience. Which is what you stated as your reason.
I meant no malice, and apologize for calling your method unnecessary, as after I re-read what I posted, I realized that it would tick me off if it were done to me.
IYAS9YAS lets his engine oil drain for 4 minutes or so. I allow mine to drain for 2+ hours. Which one use has eliminated a better percentage of dirty oil and metallic particles from their engine?
lol...
