Im finally getting gears done and I was wondeirng what is recommended now days for a Chrysler 8.25 lunch boxed with an Aussie and a D30 HP lunched boxed with a Spartan.

I just bought some valvoline and I seen it says for limited slip. Is that alright? It says it has friction modifiers in it... Or should I go back.

At least go back and check if what you got is the regular. I have seen some of the standard oils with it in there. The friction modifiers won't hurt a non LSD diff so it's not a huge deal if it's just in there. Most use either 75w-90 or 85w-140 or similar. Go no thinner than 75w-90 and no thicker than 140, everything in between basically is just going to change how loudly your diff clicks

What do you mean regular? This is the bottle. And yeah not friction modifiers, just says anti wear.

Hoooper

I would just go back and check if there is a bottle that doesn't say that on it.

No special oil needed. Use 70-90W.

NattyBoh

well I already have this stuff.

Hoooper

It will work just fine. Only reason to go back would be to see if it was more expensive than oil without the additive is what I was trying to say

They recommend 85-140 with Aussie lockers

Ohok, yeah it was like 6.99 a qt but then I used my advance auto coupons and got 41% off my total bill. Gotta love the internet.

I running aussies f/r and I useing exactly what you got no complaints

SeriousOffroad

Aussie wants you to run thick oil because their lockers are gawd-awful loud and thicker gear oil will make it less loud. If you live in a cold weather enviroment, stick with the oil specified in your owners manual.

I live in maryland, we only get cold like 2-3 mths if that a year. VERY rarely under 32 degrees. If we do it willl be maybe 1 mth
