I'm not to sure about the diff oil so I'm asking you guys and I am not sure if I should get the Amsoil 75w-90 heavy duty or LE 1605. I can't seem to find who sells LE 1605. I just ordered some motor oil from Amsoil and thought I was going to get LE 1605 for the diff but now I'm thinking about Amsoil instead but the shipping is ! $7.10 shipping for a $13 bottle! What should I do and what do you guys recommend I get. Location is GA (ATL). The weather is a concern I see and winters are down to 25-30 degrees and summers are 85-95 degrees.

where i get mine from

Either is fine. You can get LE1605 from Rick's Accessories or hardtopguy.

I usually run mobil 1 because I can always get it at walmart or the local auto parts store.

I ran Amsoil 75w110 , I would have run the LE but I could not find a local supplier for it whereas the Amsoil was easier to source. If you run the Amsoil get the 75w110 it is a better match to SAE90 IMO.

Mr._ap1

Thanks for the site. I may just run LE 1605 but just wondering how long this diff lasts in mileage and date?

Mr._ap1

I just ran both prices, Amsoil is $22.42 and Ricksk2.com for LE 1605 is $23.80 shipped. Damn I may just go with Amsoil.

Have you considered joining Amsoil's preferred customer program? It's only $10 for 6 months and would be good if you have need more fluids or have some friends needing fluids.

I just checked the preferred customer price, $10.50 for the 75w-110 and $7 for shipping.

Funny thing is that after I purchased 6 quarts of 5w-30 amsoil motor oil, I read up somewhere about the price being cheaper if your a perfered customer.. a little to late and I just thought with the life of the oil being a year, I wouldn't have to purchase too much.

I have used both with a 4.57R gearset and the LE1605 whined more than Amsoil.

I just ordered some 75w-110 severe gaer synthetic, so we'll see how it's going to turn out. 1 quart is enough I persume? Anyone have any great ideas of how to pump it into the diff?
