Customer Ratings & Reviews

Bags worked flawlessly, maybe lost a couple ounces but ease of install is worth is. Great replacement for my OEM fluid at 16k

Have had this in my front and rear differential of my Tundra for about 2-3 months now but so far so good. Even though I've only got 12K on my truck the gear oil in my rear diff appeared to be fairly dirty so I'm glad I went ahead and changed it this soon. The front diff was not bad but change it also to Amsoil.

Easy squeeze bag is the way to go.

This should be a no-brainer to anyone who wants to keep their transmission functioning properly. If you've ever looked at all the gears, pawls, shafts, bearings, etc. inside a Harley transmission then you understand just how complicated and expensive they can be to repair. Eliminate the repair expense before it bites you in the wallet by ditching The Motor Company's recommended "engine lubricants" inside your transmission. All the parts inside those small transmission housings are pushing 600-1200 lbs. down the highway every time you go for a ride. Why take chances, give all of those parts a fighting chance by using the best lubricant to operate inside that environment. When I change out the Amsoil Severe Gear oil on the bikes I service, I love the way it still looks clean and clear and the drain plug magnet comes out clean after riding 5-10,000 miles. That's the difference between gear oil and engine oil in your transmission. Great product.

Excellent product, replaced the gear lube (AMSOIL 75W-90) that was approximately 9 years old and it came out the same color as when it was new. First time using the Easy Pack and it made it so much easier to fill the differentials and transfer case, definitely will always order the Easy Pack dispenser.

Works fantastic! Rear axle is quieter and have noticed a slight increase in fuel economy.

Awesome fluid. Seen temperature drop on rear differential by 200 degrees

Rear end temps went way down

I replaced the seals and brakes on the 14bolt axle in my 2500 series GMC truck. While I was at it - I also replaced the rear cover on the axle as it was getting really rusty. Looked around for recommended gear oil to refill - and found Amsoil highly recommended. The pouches make it relatively easy to get the oil in the filler opening - but you still need to have the right technique or it will spill. Overall good so far.

Once you figure out what product you need the site actually tells you the capacity for your particular vehicle which is really nice and delivery is usually by the next day which beats Amazon buy a mile very impressed!

Awesome

EASY TO USE. GREAT PRODUCT.

This is a great product. With an ingenious container

The oil itself is amazing and works harder than most to keep my vehicles, that have over 200,000 miles on them working as they should. But my favorite thing about this product is the container. It’s so ingenious to never again have to use a messy pump and struggling to get it all in their in a confined space without making mess of the entire area. I’m not sure why the plastic collapsible container hasn’t been a thing long before now, but I’m glad amsoil has it figured out

I have road-maintenance machines with several HD gear cases. These machines run in extremely dusty, dirty, and hot conditions. I have tried several different high-end gear oils in my gear cases and monitor my oil for gear and bearing wear. After trying many different "supposedly high-end, and expensive" gear oils, I found that Severe Gear 75w140 provides the best protection for wear and high temp stability in my machines. I have spent a lot of time and money testing, evaluating, and researching the best oil for my machines. My gear cases are extremely expensive, and need frequent oil changes due to the severity of their service. Amsoil is now my go-to gear oil, and I'm also finding success with the Amsoil motor oils for 4 cycle motors that get run very hard too. Good Job Amsoil!!

Time came for fluid change on diffs for Jeep Rubicon. Amsoil severe gear lube was my choice based on too much online research. I've used Amsoil for many years on many cars and is my go to choice. Found the Amsoil website to be easy to use and setting up the garage with my vehicles provides a lot of useful information about the fluid capacities for my cars. Thanks!

My 2015 Harley Ultra Limited shifts so smooth and quiet now. Also, I can find neutral much easier!

I recently had my Wrangler regeared and the new gears made some noise and seemed to have a little too much clearance. Because I tow a small boat now and then and Chrysler recommends a 75w-140 gear oil for towing instead of 80w-90. I put this oil in and the gear noise nearly vanished and rear end behaves much better.

Why have I waited so long to try these easy packs? I will always order these in the future, makes a messy job, so much easier! Well worth the extra pennies.
