What’s changed is the oil not the physical realties of engine wear. But there are many different mileage specs for oil change intervals.

The more often you change your oil, the less amount of miles driven with your engine’s lubricant filled with shrapnel and the less shrapnel per oz it contains.

You can delude yourself all you like but the facts remain. Oil quality and quantity degrades the longer it stays in the motor. Since oil changes are cheap and easy, there’s no good reason not to do them every 5k miles.

I have a 12 year old diesel vehicle and the manufacturer recommends oil changes every 10k but the dealership and a diesel specialist have told me to change it every 5k miles. Explicitly told that almost all of the problems they see in my model are due to the 10k mile oil change recommendation and downstream wear and tear from that specifically.
