Without having to order? I'd like to try running their Oil instead of the Mobil 1 Synthetic that i run now. Do you guys think there is any advantage to the RP over the Mobil? I also want some Gear Oil and Possibly ATF as well

I switched my oil, t case, and rear diff to RP and actually saw a loss of mpg much to my dismay. I would stick with the reliable Mobil 1 if I were you. Not to mention that Royal Purple is alot harder to find and more expensive. Just my $.02

I saw it at Wal-Mart after I bought it at O'Reilly's and it was almose $2.00 cheaper per quart at Wal-Mart. I haven't seen much improvement from non-synthetic oil to Royal Purple.
