Royal Purple Motor Oil

[Dan]

Racing 21 or just standard 5w30/10w30, etc?

no, i don't want this thread to turn into "...showed that RP is crap.." only to have "... that study is flawed..." or "... m1 is the same...."

i just want to know, should i go with Racing 21 or their standard sythetic oil and why. thanks!

I use the standard rp, but if you are actually considering using racing oil and really want to know the difference, just call them. The number is on their website.

Whats the advantage of using racing oil?

i say save your money and just go with the 10w30 with Synerlec(sp?) or jsut call them like rcM3 said-good luck
