I've tested it. It will build as the Race goes on Probably 25 to 40 % wear will be there by then end of Race. Engine settings was same as 2.8. Tweaked one's are Gearbox and RadiatorMy brother is testing it now.
After 10 laps of monza. The engine is somewhat brown same collor as tyres after 15 laps and the gearbox isn't colored yet
