Some of that oiling relies on rotation to cover the wear surface

Higher performing race engines have an interlock that prevents ignition until oil pressure reaches a threshold.

Our normal engines will come up to a cold idle that is higher than normal to bring the oil up to temp and make it more viscous.

All in all they aren't meant to last forever and there is some wear that simply cannot be prevented.

Gear head question: supposedly most engine wear occurs at start up -- HokieDan95 03/21/2018 12:34PM

Don't forget that zink has also been removed, or seriously reduced from oil -- EDGEMAN 03/21/2018 1:30PM

You don't want the cylinders bathed in oil though, vehicles would smoke -- fordham 03/21/2018 12:59PM

That's why you want good valve seals and piston rings. -- EDGEMAN 03/21/2018 1:18PM

Pistol rings? You'll shoot your eye out! ** -- R J Reynolds 03/21/2018 1:43PM

I'm thinking tolerances have improved tremendously... -- `lag 03/21/2018 12:48PM

The cylinder walls and piston pins are lubricated by "flung" oil and thus -- Hokie360 03/21/2018 12:40PM

I think the wear is minimal, and with the use of synthetic oils... -- EDGEMAN 03/21/2018 12:38PM
