Royal purple oil change

[kicker417]

so yesterday i decided to make a big step and change every oil fluid truck takes with royal purple and i did notice a difference in the way it rides and my mpg increase 1.5 I did both of my differentials,transfer case,engine,transmission,and the coolant additive.This is for anybody wondering if royal purple is worth the money.

I like it not sure if the cost ratio to the other stuff makes R/P worth it though. I still havent gotten around to tranny or coolant yet.

I use it and love it. I also have the trans full of it. Now THAT was expensive. As for the cost of oil, the RP isnt but about $1 more per quart than Mobile 1. I think the 1 gal bottle is about $28 around here

[Ridinhigh]

how much would it cost to put royal purple in both front and rear diff and the tranny

[dedogg]

it cost me $200 to have a shop do it.

1 qrt of RP ATF Max was 11 bux for me and it took 17 of them in the trans. As for the front & rear diff, I would guess about 3 qrts each and I forget the price on those.

pretty close it's 2 quarts in each diff you fill the front till it comes out the hole the rear the line is 16 mm below the fill hole.

Never heard of "Trac-Rite".

royal purple already includes the limited slip additive but yeah it was a little expensive to the whole truck thats why i bought a little at a time
