Switched to Fram AF at 18,000mi. Ran OEM oil filter. The car was driven pretty hard.
RP bashers, UNITE!!
This is my first UOA. The car saw MC 5w20 from 0-1000mi. Then another run of MC 5w20 from 1000-5000mi. Changed to RP 5w20 at that point. RP went 5000-10000, 10000-15000, and then this run went 15000 to approx 22,000.
I'm sure this is a ---- report since it is Royal Purple.
Sorry, I have nowhere to host the image.
