When I was a pretty newly minted mech engineer I took a graduate level course
in bearing lubrication. Came out of it with a big attitude. Took the rest of
my career to realize just how complex this subject is. Especially in
engines.
One outfit I worked for some years back had a machine with ball bearings
running so fast that the centrifugal forces on the balls were the overwhelming
load. The product became marketable only after the switch to a 100% synthetic
oil. Sure made a believer out of me.
So what do the rest of you think of synthetic oils? Sure a lot of expense
when you get into the frequent oil changes needed on a heavy nitro burner.
