Yea i got no complaints with it. A few people in the Evo world hate royal purple and said they had it burn oil. I changed mine 2000km's ago, switched from oem (Mobile1) to RP and its at the same level, even with the new turbo. On top of that, the place i get the oil from, i get military discount
I also ran RP in my SRT-10 for about 20,000km and no complaints.
