Purchased Amsoil Severe Gear Oil for my Dodge Challenger Redeye who’s rear diff was starting to whine when turning. After changing the oil the whine went away. Thanks Amsoil !

I honestly can't say whether Severe Gear is any better than the dozens of gear oils I've used over the years? But I do know I love the handy pouch it comes in! It made changing the differential oil in my family's three Subarus very easy and mess-free. I'll continue to use Severe Gear in all my vehicles going forward.

truck handles and runs perfect

The great gear oil never had any problems with it!!!

Once again running these oils I have a sense of security.

I liked the bag. It was easy to use.

I've been using it in all of our vehicles without issue for 10+ yrs.

Excellent

Changed out the diff oil on my 1500. Trust this much more than OEM

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.

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.

A definite item to get. When preparing to change diff oil , AMSOIL SEVERE GEAR.easy to use

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...

I have switched both of our 4 wheel drive trucks and Corvette over to Amsoil Severe Gear. I am a loyal customer and believe in the science that goes in to the entire product line.

Said I would receive an AMSOIL hat or rags for my expensive oil ($166.88 total with tax) purchase and did not receive either.

In my opinion its better the OEM Mopar 75/85 gearlube. The ability to handle 10%+ water contamination and provide the same protection to me is important from temp duty cycles and condensation forming. No issues with limited slip...stuff is unbelievable....I have used Amsoil gear lubes in Motorcycles, Sleds, Race Cars, ATV/UTV, Trucks....never a single failure....

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.

This gear lube silences the dreaded 2007 HD 6-speed 5th gear noise. Make the shifts almost automatic quality!

I love the hard bottles short and do not tip over as easy as tall ones Easy to tip Knowing I have a quality product for my truck and suv rear diff is Great peace of mine

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!
