Hey I just got my chrome differential covers in!! What kind/weight oil do I use??? Dana 30 & 35.

Thanks!

75-90, if u tow alot u can run something a bit heavy. Fill them up till fluid starts coming out the plug

Not likely with the D35, but if you have a limited slip diff, you'll need a fluid with a friction modifier.

x2. Get 4 liters in all. 2 for the front, 2 for the back. If you're not towing anything, you may even wanna go synthetic. Help improve that mileage a bit

Ok cool. I do have 250k on my beast!!! Should i go ahead and go synthetic? It's my dd and weekend warrior!

Someone will probably disagree with me but if that were my car I definitely would go synthetic

x2 synthetic
