Customer Ratings & Reviews

My Diesel Ram and my motorcycles run on AMSOIL I have us this products for years they manufacture the best lubricants.

The High Quality of the 80W90 convinced me that I should use ALL of the Amsoil products made for my Duramax truck. I see now why once someone uses this brand of gear and engine oil- they never use anything else

Replaced the fluid in my Mustang gt. I did it preventative and didn’t notice any changes however I think it’s better quality than Motorcraft.

Hi I am very happy with this product it is a high quality product that I can completely count on at every level .

This is a game changer in ease of use. Makes life a lot simpler and the quality of the Amsoil product Is a bonus.

Worth the extra few bucks to have a high quality lubricant in the differential, thank you amsoil for bringing a great product to my door quickly and priced fairly, working awesomely!

got this for 2nd gen tacoma differentials. the bag is awesome, beats using a pump. oh ya, get rid of those 10mm hex plugs that strip in the front dif!! replace them with some that take a regular socket - fill plug is m18 drain is m24 threads

I love how easy it is to spray the bags in , beats using a pump. I trust amsoil is as good as they claim to be

Awesome product, and the flexible pouches makes the job volumes easier.

I am about to embark on a cross country journey with my wife to camp, hike and 4Wheel the U.S. and I knew there was only one brand I wanted to trust from past experience so I came to Amsoil and luckily I found this which has a better viscosity and I know I will be good--- with a few more changes during my few hundred k travels.

Great product and the differentials is one place where the extra money for Amsoil lubricants is 100% worth it

The easy fill packs make refilling much easier. It's more economical than the Motorcraft Fluid. I am also a fan of having it delivered to the house. I installed a new Banks Differential Cover. It's the fluid recommended by Gale Banks himself. So I am confident it exceeds the OEM fluid from Ford with is nearly 7 dollars a quart more.

I have been using the severe gear 75W-140 in my Harley Davidson 6 speed transmission for a few years now. There are clunky transmissions but it seems to quite the tranny a little. Bit I feel more secure with it in their knowing all the issues HD.s have with 3rd gear on these transmissions.

Quality Gear Oil, long lasting and minimizes wear. Noticeably less metal on magnetic drain plug.

Great stuff just wish they sold friction modifier for Ford differentials.

I could almost swear it shifts better

I replaced both front and rear differential fluids about a month ago. I noticed a change almost immediately. High-quality fluids definitely make a difference. I have no doubts that my rig will be ready to do some heavy towing!!!

Great stuff

Best ever for my Harley Trike

Love the packaging. So easy to squeeze it all in like a capri sun. Great oil with added LSD lubricant in 2017 Ram 1500 ZF LSD. No noise at all.
