Customer Ratings & Reviews

There are a lot of synthetic gear lubricants on the market, but Amsoil is my go to for all of my vehicles that require a superior synthetic gear lubricant. I don't want to change these fluids earlier than I have to and Amsoil gives me significant duration between fluid changes with confidence that the oil is still performing at it's peak.

Awesome stuff, I have always put Motul on my bike but since i use Amsiol I’m not going put anything else on my bike, my bike shift smoother with this Amsiol, only the best for my bike.

Quick and easy to use no mess or need for additional tubing on the vehicle I was working on.

These containers make it easier to squeeze the oil out. Don't let that little cap fall into your trans/diff!! Take the cap off and use your finger as you move into position. Fortunately, the cap quickly came out when I removed the drain plug!! :-)

This is what I need would just like a little more insight whether it’s for front or back

I am a big fan of Synthetics, from my boats, off-road vehicles to my daily drivers. I use the Amsoil Severe Gear in my F350. I tow a lot of client boats in an extremely harsh (HOT) environment. Annually, I tow my 43-foot fifth wheel to the Sturgis Rally loaded up with motorcycles, gear, and supplies. I never have issues with my rear end, the Severe Gear coupled with an oversized AFE diff cover keeps the rear end cool and smooth

Switched over to this Smother shifting

Outstanding Transaction

Highly recommended

Ordering and using this product is very easy. It is a top quality product that is packaged to easily enable getting the oil in the differential without any special tools. And disposing of the packaging is convenient as well.

Been using this product for a while and always does the job better than any other.

This gear oil is the best out its lasts and fights wear and keeps everythi f lubricated and the ez squeeze package makes for no mess and waste.

Works perfectly in front and rear differential of AWD Genesis, pulled smoothly at low and higher speed acceleration, no grinding or jerking anymore. I'll buy this again in a heartbeat!

Awesome product!

Got my car driving like new

Received product nicely packaged and arrived on time. Was able to fill my transfer case without using a pump. Love the plastic bag as I can go at the fill plug from different direction. A plus quality

I have used this severe gear lube in my Harley ever since I installed the Baker transmission. Smooth shifts and no gear noise or transmission noise. Only transmission lube I will use in my transmission. I believe Baker makes the best Harley transmissions and they are not cheap so I will use only the best transmission lube in the industry, that is why I use Amsoil severe gear lube.

Great fluid, the container makes it easy to fill in those tight areas. This fluid is almost clear which will be great when changing so you can tell how dirty it is, unlike the competition.

Best invention ever !! The pouch style is the easiest way to refill , clean simple and fast !

I have been using the 75 / 90 full synthetic for about 70 k it was the recommended oil when I went with Banks rear diff cover. I have everything changed over to Amsoil, Confidence and delivery to my home in just 2 -3 days most of the time.
