RE: Royal Purple
5w-20 RP in the engine and RP gear oil in the rear end. Car runs smoother than before and i use a mobil ormotorcraft filter. I thought molybdenum was good for high heat. Why do i have to coat my exhaust valve(its a 2-stroke but has an exhaust mechanism for powerband)system on my dirtbike with it??? As far as it being exhausted by engine use.........Isnt that what a Oil change is for??

What brand oil filter are you using?

I just put in RP 5W-20 today. This was my 2nd oil change; first one was at 750 miles with Motorcraft 5W-20 semi-synthetic, now this one at 3000. Engine seems to run a lot smoother and quieter. I'll send it off for an oil analysis when I change again at 6000.
