that's a claim that demands some evidence...got some ?


The thinner oil flows from the rod bearings faster providing more cooling oil to the piston. You know, like in power plants more flow transfers more heat. Get out your thermo book.

With a positive displacement pump that shifts the same volume of oil for each and every revolution ?

The oil pump bypasses oil at anything above fast idle.

What?
First off an oil pump doesn't bypass anything. Some new engine have an oil pump that is variable,meaning basically it's able to adjust volume depending on engine needs however I'm not aware of any pump that is able to bypass anything.

Either the engine has a bypass built in to the oil circuit and when pressure exceeds a specific psi it will bleed off the excess pressure back into the pan,or the oil filter is equipped with the bypass valve.

So again. You're incorrect.

This isn't even fun anymore. Pointing out the flaws in your posts is getting old. It's such a common event lately that it's become stale.

Thanks for trying though.
All a steer can do is try....eh

Here's a refresher for the 2 of you on how an oil pump uses the internal bypass to regulate pressure.
