you can get RP at the door or at a dealer close to you. you can order it cheap from oiltown.com. i have it and love. no scientific proof but my turbo spins down much slower now. when i am in the parking lot now and and running in 1st gear moving 6 mpg and push in the clutch all you hear is a long drawn out falling pitch of the turbo. sheeeeeeeee. got 7000miles on the 1st crank of RP and am changing it out again today.
RP nano polishes all metal surfaces. this is real good for the turbo bearing (molybdneum resists 500,000 psi shear force)
