It is about time to change my differentials after my gear swap. Just wondering what everyone thought about going with amsoil or synthetic for that matter? Thanks for your time!!!

 

I changed my diff fluids around 5k I think, used valvoline synthetic. It was amazing how much metal and slag was in there. The oil came out a metalic grey color. I only use synthetic fluids whenever possible.

 

I run royal purple in everything except the oils pan and the tcase. I think it makes a big difference.

 

Thank you both!!!

 

What weight is everyone running?

 

I run amsoil in everything in my jeep. I used severe gear oil in both diffs and I noticed a difference, especially in the colder weather. In the manual it recommends two weights depending on if you tow or not, I chose the heavier weight just for the added protection even though I dont tow at all.

 

Thanks again. Just order some Amsoil 75w-90 for the front and 75w-140 for the rear. Thanks again for your responses!!!
