Customer Ratings & Reviews

The product is far superior than others on the market....however even the top manufacturers run discounts several times a year.....wish Amsoil would pickup on this incentive

Best of the best

After about 100 miles the transmission quieted down shifted smoother and no longer banged into 1st gear

Product is as described.

The only tranny fluid I use in my HD Roadking.

I purchased AMZOIL for the first time about 3 year's ago when I bought my first Harley Davidson and AMZOIL is the only lubricant I use. I now have just over 53,000 miles on the bike and no problems.

No issues for 80,000 miles

This is the only product I put in my Harley-Davidson motorcycle.

I love the way it makes my bike shift nice and smooth and makes finding neutral easy

Shifting is smoother, 1st gear "bang" seems to have disappeared

keeps my motorcycle cool and quite, will continue to purchase.

If you want smoother shifts and finding nutral all the time use Amsoil products

I started using Amsoil August of 2012, while at the Sturgis bike rally. I was impressed with the information provided and the results of using their products over the past five years. I'm a now a lifetime Amsoil customer.

I have family members and friends that use this product on their Harley Davidson with great results.

Best stuff ever!! Used in Harley Street Glide Trans and get rid of all noise that harley oil has.. Would recommend to anyone!!

I use this in my Harley and will definitely buy it the next time I change the transmission fluid.

Happy with product. Quite shifting and easier to find neutral over factory syn harley oil

I was using competitor's 85/140 Hypoid in my Harley's transmission and switched to Amsoil transmission fluid. It was immediately apparent that it's too thin. The gears were clunkier and loud. After 1000 miles I switched to Amsoil Severe Gear 75/140. Problem solved, back to quiet and smooth again. Will stay with Amsoil Severe Gear.

I can't believe how much easier the bike shifts from gear to gear since I changed to this transmission fluid. It is a real noticeable difference.

Changed the fluids on two holes (Crank & Tranny) on my 2016 Harley Softail Deluxe. Used Amsoil fluids for both. This was the first fluid change I personally did since the factory warranty at 1,000 miles. Factory had used some other synthetic fluid which was an improvement from non-synthetic. But what an incredible difference after doing my own and switching to Amsoil. My moto seriously runs much cooler and the tranny feels great when shifting. I fell in love my bike all over again. Plan on continuing to use and will soon try out the Amsoil primary fluid.
