Royal Purple is known for being horrible. They have a great advertising department but anybody who does thier research will find the truth. I forget what organization it is that actually sets the standards but Royal Purple doesn't even meet the requirements to be considered "motor oil". Stay with Mobile, Shell, or Amsoil.

It's not that Royal Purple can't meet the latest "energy conserving" API spec (starburst logo), They probably just don't care to change their additive package just to apiece the API.....which has EPA written all over it.

Amsoil does the same crap, Alot of their fluids have "recommended for use in" with no license to back it up.

Fact....There is NO miracle oil;)

And just be aware,, there is Royal Purple, then there is Royal Purple

The street grade is just marketing hype and petroleum die. It's like the ****fire spark plugs and Fram filters and multi electrode exotic metal spark plugs, PROOF there is a sucker born every minute that will believe anything if you throw enough pretty girls in bikinis and fast cars on the face of your advertisements. (no insult intended to anyone buying it)

Then... There is a HUGE difference between that street grade RP and the $13 a quart XPR racing oil. RP made a name for it's self in providing a high pressure lube to help keep racing motors alive. It DOES that job if you buy the RIGHT lubricant for the job. But because of the 'magic' in XPR, it's sold and labeled as NOT FOR HIGHWAY USE ONLY.

Just like Edelbrock, Fram and ACdelco.. If they can make a buck from the name,, they will sell you anything
