I started using this back in 2008 after speaking to a rep and someone who used the product he sold. I researched all of the findings and found the product to be superior to others.

I used it his gear oil for my older 4 door Suzuki sidekick. And can really tell how great it works, quieter running gears, cooler temps. And last a very long time between changes.

I like all your products that i have tryed and will buy again

I use in my Jeep Wrangler, rear differential!

I believe fully that Amsoil synthetics are the class of the field in all applications , I use their engine and mix oils in my quads and jet ski , so I seen their extended life gear oil I had to get it for my pickup , it might sound like an ad , but , Amsoil is all good stuff ??

I put this in the rear ends on my Kenworth, so far so good!

Worked perfectly....

Excellent product. The only fluids I use on my car and trucks.

Use it in our work vehicles. After the discount it's cheaper than any auto store

It's difficult to give a review of a long term oil such as differential lube. But, Amsoil in my 4.2 and my 4.0 Jeep engines was immediately noticed. Jeep in-line 6 motors tend to have valve noise on start up. Totally gone now ! Love that Amsoil ( 10w30). Now switched all 3 Jeeps to Amsoil
