Gear Oil

What weight gear oil should I use in my axles? D60 up front and I think Stearling in the back.

My earlier post was for the front end. For the rear end I would use a more viscous solution. Click on the link that was provided and read the paragraphs at the bottom. friction modifiers should not be required with the blends listed.

Add on
NOTE: AMSOIL Synthetic Gear Lubes do not require the use of the additive "Friction Modifier"

I use 80w-90 in both. No probs yet. I have a LS in the rear so I had to use one the the 4oz tubes of the friction modifier.

75w-140 synthetic is the spec for the rear. I run the same in both axles myself.

You will have to read the labels.

Some require the friction modifier, some have it already added so it is not required to add more.

I am running 75-140 synthertic in both of mine as well.

From what I have seen, most of the synthetics do not require a friction modifier.
