I use the RP. That ____ is actually purple! Yup, I'm one of those dip ____s that thinks colored oil is cool. :shock:

I have been using royal purple for years, I am a big fan. I cna't document any performance gains, but I still like it. Bill

I'm using the Royal Purple and love it. I also put their manual gear lube in my trans, it definatley made a difference in the shifting.

How many miles should you have on your car before going to synthetic??? I heard that you need to wait for seals and things to seat or something????
