a couple of questions
Working temp for oils in an engine, would that be between 80 and 100 degrees?
also
am i right in thinking, a SAE 60 oil is 70% thicker than a SAE 40 oil
at a temp of 100 degrees
So making a SAE50 oil Approximatly 35% thicker than a 40 at 100 degrees??
Surely in Real terms, you would see huge difference between them?
as in to actually look at your oil pressure gauge when up to temp
you would notice a big difference between them??
thanks!
