i think the oil its like $5 a qt. at KOI so i bet it is fair in price for the diff, and trans.

You don't need friction modifier when you run the RP stuff, as it already has it in it.

I'd stay with Mobil 1 in the motor, RP's oil doesn't last the mileage (breaksdown) that Mobil 1 does.

How my buddy explained it to me, he reads into this site alot
