Hey Bill,
Here is the independent study I was telling you about that has convinced me to stop using Royal Purple:
A Study of Automotive Gear LubesOut of 14 lubes tested, Royal Purple finished 3rd from last. I've been a proponent of RP since 2003. I have it in my truck (both axles, all three transfer cases, and transmission) and I've also been running it in my MR2. Not any more

Thanks
Mike
