Word to the wise. Stick to your factory oil, or what you like. I have used to RP in my car, to say i wasn't happy is an understatement. High lifter wear and related valvetrain failures.
Best place for RP is on an ant hill or fence line.

 

What is RP?

 

RO_AL PU-PLE

 

Never used it. Don't know anyone who has. I use only Amsoil. Others I know have had good luck with Mobil 1 also.

 

Royal Purple?

never heard of it.

 

i heard of it its suppose to be good stuff?!?!

 

Amsoil for me. It's treated me well in my sleds.

 

Royal Purple is great stuff! I have been using it for years in everything I own. My .02

 

How do you know it's good stuff. Just becareful, I thought the same until I started having valvetrain problems on my car. Switched back to racing Valvoline and problems have stopped.
Most people believe oils are great because they aren't having any problems or haven't torn the engine down to see. I believe changing your oil and filter regularly is the best policy.

Royal purple is suppposedly good stuff. I dont know though.

I would say, there are much better things to put on ant hills and fence lines, prolly cheaper than RP too.
Not a good idea.
