No reason to leave the drain plug out for two hours
I asked you this:
1#. Do you think dirty oil and metallic particles are not remaining and clinging to engine parts after you quickly screw the drain plug back in?
Yes or no?
#2. Allowing engine oil to drain thoroughly does not help eliminate a good percentage of dirty oil and metallic particles?
Yes or no?
I know why you evaded the questions, because you were wrong, and you couldn't admit it and instead danced around and evaded the 2 questions.
That's pretty dang pathetic.
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.
