Customer Ratings & Reviews

I use Amsoil for the differentials on both my trucks. Top of the line product, always shipped promptly

Oil was good quality and very well packaged.

Time will tell but all looks superior. Used other items from Amsoil with great results. Thanks.

This is my first purchase of these lubricants and I have complete confidence in them, but I'm just disappointed because they didn't send me any decals or stickers.

Works as it should installed Banks rear diff cover and used Amsoil as recommended.

Great oil! Easy to use website. Great job Amsoil 👏

Fluid was great, cleaned out my differential. Packaging was great. I’m going to continue to use for sure!

love how easy the gear oil was to put in my rear dif BUT one of the bags had a small hole in it and was leaking all over the box and everything outside of the box. Wasted $85 dollar bag of gear oil.

Excellent high quality product i use this in my M35A2 Deuce and half longer gear life reduces heat for sure much better lubrication

I don't do to many reviews but for the service I got I'm going to share. Long story short my last two orders were not right. The first one was just lost somehow I had a tracking number and watched it get to my city then it told me to file a claim. Second one came the box looked like it had been in a car accident and had a couple of the items I ordered. Both times my products were replaced and sent to me right away. I had photos and proof of my missing items so don't try to pull a fast one they check Sending my items to me right away when they found out what had happened showed me who I'm dealing with and why I use Amsoil in everything my family owns. It's worth a couple extra dollars to know people care and have one hell of a product line. I have a Maserati Gransport Spider with a Ferrari f136 engine 4.2. Every fluid is by Amsoil except the clutch cfh11s. Y'all Mazzi owners reading this don't be scared you can feel the difference in performance. Thank you Amsoil and my dealers for taking care of me when the mail system fails

You can feel the grip

Hauling a 39ft 5th wheel and want extra protection. This oil is everything you need for heavy hauling.

I like the packaging/container that the oil was in. It actually proven to be very helpful and I have never used oil in this type of container before. For my particular application, this was absolutely awesome. Though before I ordered, I called customer support about questions on this product. And honestly, the lady didn’t even seem like she cared to talk to me. She did not seem enthusiastic and that she was just answering the phone call because she had no other choice lastly, I was supposed to get a free gift and it didn’t come with my order.

Im very pleased with my amsoil gear oil for my transmission

Excellent product

Great trusted product.

Great trusted product.

Easy drain & fill with the bag container instead of a bottle. At 28K diff fluid change made a noticeable difference in how quiet the gear noise was in my 2023 Ram 1500. I'll be putting it in my 2026 soon. Thumbs up Amsoil.
