I am not allowed to publicly post prices but, if the Forum will allow me, I will sell AMSOIL at Dealer Cost...

Just as anything, there is good and bad to Royal Purple. I will find the good one day.. LOL

Seriously though. As in the case of their 10W-40 oil. It shears out of grade in the First Sequence of a 3 Sequence ASTM Test.

I have seen many posts claiming more HP... At what expense ? Dyno claims need to be backed by other facts such as ASTM Testing which Royal Purple does not have.

Royal Purple has been asked to stop their present advertising or they will be taken to court.

The link I had is no longer valid but I hope to have it up on my website this weekend for all to view.

Cheers all and have a safe Memorial Weekend !
