Engine/Transmission (1998.5 - 2002) Amsoil and what weight

[Don Bellamy]

I am looking to change the oil in the front and rear differential, the front is the Dana 60 and the rear is the Dana 80. I would like to use the Amsoil, what weight would be recomended and is the Amsoil the way to go?

Amsoil is good enough, but I'd also encourage you to consider Royal Purple and Redline gear oils, which are also very good.

If you tow heavy trailers, then you want a 75w-140. If you don't load the truck that heavy, then stick with a lighter 75w-90.

Personally, I'd use the thicker stuff, as the supposed mpg increase of the thinner stuff never materialized for me.

I am running 75-140 in my dana 80. I am 2wd, so hopefully somebody will chime in. Also, I did not need any limited slip juice.

I have pulled 13K+lbs with a 10Klb truck in the hills all day long wth Amsoil Severe Gear 75w-90. No heat problems at all. 75w-140 won't hurt anything if you decide to go that way. Shouldn't need any friction modifier for your truck.

I use the RP in everything.

I did see a mpg increase in my jeep xj when I changed the diff fluids. Not in anything else though.

THanks for the info, I did mean to ask what the front and rear hold? My owners manual states one amount and the service manual states another?My owners manual also claims I have the Dana 70 in the rear instead of the 80 which I know I have?

 

[Diesel Nut]

What is your truck? If you have a QC then I would assume its an 80. Look on the inside of your glovebox. There should be a lable there that should tell ya. In any case, here ya go -



Dana 60 front - 8. 4 pints (4. 2 quarts)

Dana 70 rear - 7. 6 pints (3. 8 quarts)

Dana 80 rear - 10 pints (5 quarts)
