Thanks for the links, but I use Mobil-1 100% synthetic oil in all of my cars, I don’t think I will have to replace any engines any time soon.

Most engines fail because of an overheat event. Unlike the cars of years gone by, you get no “do-overs” with an overheat event on modern aluminum engines. Overheat once and you’re doing a head gasket R&R.

I’d rather have a used car that used dino oil and got regular cooling system maintenance than a car that ran synth and had a neglected cooling system.
