Yes.So the wear of the engine remains permanent even changing oil and doing the overhaul to the engine?
But that kind of permanent wear only happens after a certain mileage. I don't have the exact numbers, but it's somewhere around 10.000km.
Before that oil changes and engine overhaul do restore car to their factory settings (completely reverse any wear).
And in theory BOP races also restore the engine, so if you only do Sport Mode you don't need to worry about this.
