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 bought this lubricant specifically for my 1962 Ford Galaxie to replace the O.E. 90 weight that was installed in 1962. I've used Amsoil products since 2005 and will never go back to conventional lubricant. Its been good to me all these years and my classic car likes Amsoil too. It has made a big difference for my classic.

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.

Completly serviced my 2015 GMC Sierria Denali 4x4 and I can tell the difference! Transfer case is smoother! Engine quiter! Gives you a feeling of confidence you can do what the truck is built to do!

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 😊

Setup gears and lockers for off road use. Always recommend or install Amsoil gear lube after my work is done. Feel very confident in a successful job especially when using this lube.

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

This really do last a long time and no issues with over 50,000 miles since changing my rear differential and transfer case and the fluid is still clean.
Reviewed by David:
Put this in my 2wd Tacoma open differential, 10,000 miles so far and no issues. I purchased the premium AMSOIL synthetic product for its superior quality and long service life... will last longer and protect my vehicle better than conventional, so in the long run it's definitely worth the added cost.
