SEVERE GEAR is designed for those who demand the best. Engineered with high film strength for high-load demands. Reduces friction and provides the ultimate protection against wear. Excels in extreme temperatures. Helps maintain efficiency and outperforms conventional gear oils. Excellent for all cars and trucks, but especially well-suited for towing, hauling, racing, commercial use or other severe duty.
Delivers excellent performance in hot and cold temperature extremes.
Resists breakdown from high heat, preventing acids and carbon/varnish formation.
Wax-free construction improves cold-flow properties, improving fuel economy and cold-weather shifting.
MAXIMUM WEAR PROTECTION
Specifically engineered for maximum performance in severe-duty applications.
Maintains viscosity for long-lasting protection against metal-to-metal contact.
Proprietary AMSOIL additives form an iron-sulfide barrier coating on gear surfaces, providing the ultimate line of defense against wear, pitting and scoring.
Helps prevent "thermal runaway," a phenomenon caused by a lubricant’s inability to control friction and increased heat under high-stress conditions.
Inhibits rapid lubricant degradation and component damage, helping equipment run better and last longer.

Good Oil, Convenient Package

The oil itself is commendable, but the package is convenient for filling in awkward spaces. Tip: if you need less than 946 ml, withdraw the excess amount into a measuring cup, then just squeeze the amount left in the pouch in one shot into your transmission or final drive or whatever.
Bottom Line
Yes, I would recommend this to a friend.

Due to a transmission issue and engine oil change being due I decided to do a complete Amsoil filter change. I can’t tell any difference with the rear end fluid change audibly but if it does what the engine oil and transmission fluid did I will be happy.
Bottom Line
Yes, I would recommend this to a friend.

The Amsoil pack is waaaayyyyy easier to use than other brands. I bought the Banks rear diff cover kit, and Amsoil Severe Gear oil was included. I think Gale Banks knows what he is doing...
Bottom Line
Yes, I would recommend this to a friend.

Impressed with the Easy Pack

This was the first time I had used the in-bag Easy Pack option. I had heard others say it was great but did not think much about it. My experience was really good. The bag allows full use of all the oil in the bag, and it is no mess and easier to get to awkward locations. I recommend it. I will start using it my boat sterndrive and any other application that the bag adds convenience.
Bottom Line
Yes, I would recommend this to a friend.

I started using Amsoil products 15 years ago in my marine 9.8 Nissan. Was so impressed cautiously started using it in my 2018 Chevy Colorado. In my new 2021 Colorado its all i use now. Everything is snoother. Cold starts, hit days , my son is a mechanic, maintenance and fluid changes will double the life of a vehicle! Amsoil seems to extend it even further!

I've used this gear oil before in my 2010 Lexus GS 350. When I purchased the 2013 GS 350 I immediately drained the gear oil out and replaced it with Amsoil.
100,000 miles later I'm changing it again. I think it offers better protection than any other product. I've never worried about protection when I use the Amazon product.
Bottom Line
Yes, I would recommend this to a friend.
