I have been using amsoil motor oil so when I bought a Banks rear end cover I ordered the amsoil to fill it with the best oil that I know of and trust for my Dually

Changed this gear oil last week on my 2015 Mercedes SL550 with 25,000 miles on the vehicle. Not sure if anyone could tell the difference from driving it, but with Amsoils reputation I'm certain it's the best I could use. That's all you can ask for.

No more noises more miles less gas. On the mark Amsoil as always Thank You.

I use all Amsoil products

Makes it much easier without pump to get it in tight spots.

I used it in my highlander for both front and rear def. I might use their engine oil 0-20 for the highlander and also my Acura TL but it is little pricey.

The fluid in my rear diff didn't look or smell burnt, however, I had a slight whine and occasional squirmy feeling at the limits of cornering when a single tire would break loose before the other. Amsoil Sever Gear alleviated both issues and combined with engine and transmission oil I have gained a not insignificant amount of mpg as a nice extra benefit!

I use Amsoil gear lubes in all of my cars for top level wear and corrosion protection.

Shipping was quick and can’t go wrong using amsoil

Want your stuff to last use this

Makes that 6 speed change better

Have been using in my GMC Sierra 2500HD for years. I tow a 5th wheel to the maximum weight capacity of my rig. Works great so far and no issues.

Replaced oil in my front and rear differentials. I’m sure it will be better than OEM. At a better price

2004 Chevy 2500 hd 4x4, 6.6 with 230,000 miles. Seems to have quieted down both front and rear differentials with about 500 miles since oil change. I'm very happy using Amsoil for all my fluids.

Never hesitated to put in my snowmobile gear case. Always feel good at below zero temps, lubrication will be there.

Excellent product!! Would definitely recommend this to anyone!

I like the protection it supply’s for the equipment

I changed out the front and rear differentials in my 2013 Cayenne GTS with this. I noticed an immediate improvement in drive-train noise and vibration, better shifting, improved operation of the rear diff locking, and even an improvement in overall mileage out of the vehicle. Solid product.

Just replaced the differential oil and cover with Amsoil severe gear oil, and a Banks diff cover. My 07 Ram is good to go as far as the differentials are concerned. Thank you Amsoil for making a superior product

Timely service and a quality product ,what more can you ask for
