Customer Ratings & Reviews

Just swapped into my GMC and the job was so much easier with these bags not having to pump or figure out some crazy way to refill my front and rear differential especially in limited space.

Shipping was quick. Containers make it easy to put gear live in differential without getting other tools dirty.

I like their oil. I use this stuff exclusively. I live remote so easy to order and fast shipping.

Have used severe gear in my 4x4 vehicles. Nothing else touches my gears! HIGHLY recommend.

After using the other products from Amsoil I wouldn't think of putting anything else in my truck.

I installed a Banks Ram Air Differential cover and Amsoil 75/140 Synthetic. I am looking forward to lower temps while towing 22K across country.

Believe in the technology, have use it in my last 3 vehicles.

So far so good. Sent right to the house and no issues. I did not get my free gift thought. I am still waiting on a funnel

Best on the market

I have been using Amsoil for my engine and decided to use this gear lube when I upgraded my rear diff cover. I love the easy pour bags.

Recently drained differential for regular servicing and used amsoil this time and am very happy with the pouches which helped

Great product. Very easy online ordering. Timely delivery. Ordered extra product and shipping back to WI was costly so I attempted to exchange at local Omaha, NE retail outlet and purchase $120 of engine oil but the retail store refused to exchange a $20 gear oil for a much larger purchase.

If you want best of the best for your car ,truck,ATV then get Amsoil Severe Gear.

The fast packs are super easy to use, oil works great, what else are you looking for.

Great product

If you drive a 14 to 18 1500 this is a must. 4wd differential and rear end fluid change and watch a little magic happen with your mpg.

These easy fill lids made changing my oil a walk in the park. No seepage and no mess. I would highly recommend!

This is a genuine transmission oil. Manufacturers recommend using the same oil that you use in the oil system in the transmission. Using the Amsoil Severe Gear oil in the transmission was a whole new experience. Smooth shifting, cool temps and no gear sticking are all benefits. I have recommended this gear oil to all my rider friends and family. Thank you Amsoil.

I very much recommend this in Harley transmissions

I purchased Amsoil Severe Duty Synthetic 75W-85 Gear Oil to replace the fluids in my 2020 4Runner front and rear differentials. Perfect match per factory spec. Easy fill bag made it so simple and mess free with no pump needed!
