Customer Ratings & Reviews

Were always looking for ways to quiet down the clunky Harley transmissions, I have tried all different types of fluids and recently tried the Amsoil 75W 140 severe gear lube and it really does make a difference. It's also easier to find neutral since switching to it.

Great product! Use in everything I care about.

Outstanding fluid. Transmission runs smoothly. My only complaint is one of the packs was leaking when I received it.

Absolutely the way to go in my street glide transmission. Takes some of the Clunk out when going in to first gear. Does a excellent job

Good product that will last at least 75k miles under normal driving conditions. Used in front and rear diff of my 2018 Sierra.

I used this on my 2014 Jeep Grand Cherokee SRT Front and Rear differentials (with 50K miles) and after an over 1K mile road trip my truck is nice and smooth. Thank you Amsoil

This is the only gear oil I have used in all of my BMW'S in the last 7 years. I think it is the best.

I am returning from a long distance motorcycle tour and needed replacement rear oil for my two motorcycles. I like the thought of the soft bag instead of the hard plastic bottle and hope to be able to fill the rear directly from this bag. Friends of mine use Amsoil and highly suggest using it.

Swapped this into all of my diff’s, really makes a difference. Great price also

I needed to change the differential fluid in my Dodge pickup and after many recommendations I decided to go with Amsoil. I wanted to use the best product and the packaging is perfect. Easy to fill up the differential with this. It’s worth every penny!

I've been using this on my Tacoma now for a while. The squeeze part works really well , & Amsoil products are high quality. Recommended!

Have been using it in my trucks & motorcycle for at least 20 yrs. Not a single issue so far.

I have used this in my truck and have never had a problem. Definitely use again.

I checked my rear end before and after woth a thermal imagining camera. Same trip very close air temp. Grated the ams oil is new and the factory stuff had about 31k but I'm seeing less heat after change.

Works darn well and the squeeze container is sooooo handy.

This is the best gear oil in a very convenient application pouch for easy filling.

Did a service on the rear end of my Excursion with a new Banks differential cover. I was able to fill the differential without putting the vehicle on jack stands because I could fold the easy pack over to get it in position. Didn't spill a drop, no funnels needed. The standard bottles would have been a hassle compared to the Easy Pack. Didn't notice any difference in performance/noise after switching to Amsoil 75w-140, but the new stuff seemed a bit more viscous. As long as it does it's job, I'll be a happy camper.

Very nice

Excellent

Great product received in a reasonable time. But didn't receive the free gift magnetic tray i was supposed to get 😢
