I'm thinking tolerances have improved tremendously...

like Edge mentions below the oil has improved tremendously also in the last 10-20 years. The oils are lighter these days, 5-20 type stuff instead of 10w30 etc. Probably a few chemicals in there too which coat the cylinders.

I know the instruction manuals going back a few years already tell you to start driving in 30 seconds instead of warming up the car. ie, get it up to operation as quickly as possible.

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

Some of that oiling relies on rotation to cover the wear surface -- typed by ben 03/21/2018 12:42PM

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
