anyone ever use this stuff? i was wondering cause my friend used it in his camaro and it most def runs smoother. right now i use mobil 1 synthetic 5w-30 and im quite happy with it. does anyone here use royal purple?

 

I have been using it for 2 years now and the stuff is great, expensive but great. The only thing that might be better than it is amsoil.

 

Why do you use 5w-30?

 

well..... i put royal purple in my trans and today i had transminsion problems.... (lol) not blaming it on the fluid because i am pretty sure it isnt, just thought id throw that out there. well if u want some free transmission oil then u can come to dilworth town road and i left a huge puddle of it! haha

 

Royal purple has been around for a while and I know that the people on the Z06 forum use royal purple and amsoil, so believe me it is not going to give your car any problems. You can also go 15k miles and just change the filter out half way between that. I usually go 7k miles and just change it out.

Bijan, I use 5w-30. What do you use?
