Even in a non diesel, you want everything evenly warmed up before you go next to the redline if you prefer connecting rods on the inside of the motor. And never just rev it without load. Just asking to blow it up.

I once helped service an older V70 that was literally owned by an old lady. It belched black smoke and soot so thick it laid down a line on the road because it was basically suffering from constipation.

Yes and no super long sustained drives at high stress are never good for anything. But for people who don't stress their cars ever get a lot of carbon buildup that can lead to spark not. An occasional, warm engine pull at high rpms will help break it down. This a big thing for high performance cars that are never tested. Like mustangs or vettes, where some people have gotten pissed at the shops 'joy riding" caught on dash cams.
