Looks Like Royal Purple Got Call Out

Oh crap. I was going to change my oil this weekend too. Looks like a move to Mobil 1 is in order.

Nobody is saying RP is a bad product - just that they have not done enough recent testing to back-up their marketing claims. It's still got the API seal, they've just not done the legwork required to display the starburst symbol.

Same here! That article is just to proove that RP has exagerrated their claims of performance and mpg. No complaints here! I got 1 mpg more after just the engine oil swap....

Southwest Research is a serious reserch company. They are a big contributor to certifying the latest emissions engines for major diesel and gas engine companies. I have never been happy with RP. My engine temps are always higher and the motor seems louder. Mobile one is not fancy but it is what it says it is.
