first time user of Amsoil. what a difference it makes. did differential service on my 4wd vehicles. they roll allot easier. have already ordered my engine oil and filter for next oil change.

Product speaks for its self

I have used this product in commercial outdrives for over 10 years. Good life and no broken gears in all those years

I replaced the OEM oil in the manual transmission on a 2014 Subaru Outback at about 60K miles. In the cold weather it was difficult shifting from neutral to first and first to second gears when cold. Shifting improved when the temperature increased after driving several miles. Therefore, I cannot recommend this lubricant for the stated application.

Has always served me well in all my vehicles, whether its the engine, (gas and diesel) Transmission, or differential. I have lived in Florida and in Minnesota and have always had the flow needed to keep things lubed.

I run it in everything I own

I do a lot of towing with my vechile, from pulling large wagons such as gravity wagons and livestock trailers. I live in colder climates and never have trouble with my engine turning over hard.

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
