I get that there are lots of factors at play, hot oil will run faster. Modern cars run super thin oil to begin with, etc.... So it certainly sounds like it could accelerate wear.

And I've always thought that it could/would wear the started faster. But it's also been years since I had to replace a starter in anything < knock, knock, knock >.

Fair point, the worst wear is cold starts. I’m sure a hot start isn’t nearly as bad as a cold tight engine with minimal lubrication. But I’m sure it’s not nothing either. It’s not like most cars have an electric oil pump to keep pressure up while sitting idle at a red light.

To Joe’s point a couple of posts prior, it’s not like dealerships and car companies care, especially post warranty.
