my truck has 120k and i'm thinking of changing the differential oil
what limited slip additive is everybody using with dodge gear oil

thanks

 

I wouldn't put Dodge gear oil in it. You should put synthetic oil in it. I use Amsoil, but you can make your own choice. With Amsoil, if you even need any LS friction modifier, Amsoil has that too, and it smells better than the Dino version. Be frugal about adding it, whatever you decide, because you can put too much in there and make the LS work less efficiently.

i run mobil 1 75-90 no limited slip additives... takes 3 for the front and 4 for the back.

 

I'm running Castrol synthetic 75w90 with 1 dodge rear diff additive in the back..

 

I'm running Valvoline synpower 75w90. It has additives already added.

 

Ditto here. Mobil is the stuff and I didn't need any LSD additive, although when I changed mine it seemed people were using whatever the local parts store had.

 

I'm running Amsoil, I still needed LS additive .

 

The Dodge L/S additive is the best IMHO, I have worked for a Jeep/ Chry dealer for 12 years. The new stuff isn't very stinky, the old stuff was the best for practial jokes.
I run 75w-140 syn and 1 additive in the rear of mine, takes care of the shudder.

 

I changed mine at 64k to Amsoil Sever Gear 75w-90 w/ LS and she rides on glass!

 

I put Royal Purple 75w-90 in mine. I did figure-8's and it didn't chatter. So I didn't add any friction modifier, but I got a bottle from the Dodge dealer just in case.

 

thanks guys
