gear oil w/powertrax
I ordered a Powertrax locker today for my 29 spline 8.25. It should be here tomorrow and I hope to install it this weekend.
I have heard these lockers operate smoother with heavier weight gear oil. Does anyone here know if this is true, and if so, what weight do you recommend? |
75w-140 full syn is good juice.
|
i have the same set up and wondering the same thing. is this the best option 93?
|
ya. i ran 75-90 when i first put in my lockright in my old 8.25, and when i threw 75-140 in it was definitely quieter.
|
I have a EZ-Locker and its is quieter also with the 75w-140. I am thinking of going to an SAE 250 next change to see if there is a difference.
But.. if you do alot of street driving and MPG is your concern, than using a heavier viscosity gear lube is going to sacrifice a bit of MPG |

that is insanely heavy. in the cold your oil will turn to sludge. no, it will be sludge actually. dont do that.
Mine is a trail rig only... so it really doesn't matter. I thought about getting a bottle and putting it out in the garage for a few days and see how it pours at sub-zero..... |
I would stick with some good synthetic 75-140 that has friction modifier added to it.
|
Thanks guys..I bought Mobile 1 synthetic 75w140. I will let you know how it comes out.
