Customer Ratings & Reviews

Fabulous product reduced temperatures in my 215 mm Mercedes rear car is 2006 Chrysler Sr T8 mildly built 6.1

M8 6 speed trans shifts much smoother and quieter.

The packaging is very convenient making fluid changes much easier. Thank you!

Great product, great price, ease of use.

These make it so easy to fill differentials! 😎

I switched to Severe Gear after running 20w-50 in all three holes for 20k miles. It definitely helps with the "clunk," and I feel much better running a heavy gear oil in my Harley. I can definitely tell that my bike feels much smoother with this gear oil as opposed to the 20w-50 I used previously.

I like the gear oil and the easy to fill bags.

AMSOIL products are the best y I y can buy. Been a advocate user for 40 yrs. The squeeze bottle application is a guaranteed no mess use.

This oil surpasses manufacturer specs. I'm picky so I use Amzoil

This product surpasses the manufacturer specs. It will work well in my Chevrolet 3500

This is well put together, gear oil is the longevity of the load. It’s insurance for the long haul. Again!! Keep the same formula, don’t mess up what you have going strong.

First time I used the squeeze bags, made filling both differentials a breeze. My truck now runs solely on AMSOIL products.

I am very pleased with the results gained by the use of this great product in both front and rear differentials and give it my highest recommendation!

Love this stuff this is the second truck I used this gear oil I am pleased with the performance

My 15yo grandson recently purchased a 2000 Jeep Wrangler as his project vehicle in anticipation of getting his driver's license when he turns 16. He and I are methodically performing maintenance and changing all fluids to AMSOIL products throught out the vehicle. I believe this will be the best approach to giving him a head start as I hope he follows my lead in the future by continuously buying AMSOIL products.

Used amsoil on my diffs both front and rear with additive in rear only and haven’t experienced any funny business. By the way amsoil meets and exceeds oem.

I have used a lot of different oils and I'll have to say amsoil is the best in Quality and price.

Did a service on my F-150 while replacing the rear differential cover with an aftermarket cover with drain, fill plugs and magnets. Used AMSOIL severe gear 75W85. I couldn't be happier.

Really helps keep the differentials cool
