It should last in my Diff and T case longer than I do.

amsoil is the best

I purchased the bags of my recommended gear oil which worked well for the rear differential. Next time I will still order Amsoil, but the way my transfer case is set up on my Toyota. I will order the quart bottles for that particular application. Definitely easier to pump it in with everything that was in the way. Highlander is running very smoothly with the amsoil. I was even able to use the pump on the squeeze bottle, just couldn’t get all of it out. Definitely will be a return customer.

I've always used Amsoil products in my tractors and atvs because I trust these are the best lubricants money can buy. I can place an order and have the product on my doorstep in a few days. These people are great!

I have a G80 Eaton Locker and this is exactly what I needed for it.

Good diff gear oil!

Simply the best. Exactly what my car needed. Running smooth and quietly

I’ve recently made the switch to ams oil in my 2015 Silverado after conducting several stress and wear test of my own in our shop I was so impressed with the wear properties of ams oil that I’m going to use it in all our equipment around the farm as well as our personal vehicles

I am using Amsoil in this truck since recently purchasing it. Once I change the fluid again and have it analyzed I will know for sure if it was worth the money. 4 stars because of this. I do think from what I have read that Amsoil is a superior product, but I will not know until I use it for a few years.

Awesome product ., use it on my gear box of my Aeromomemtum Engine

This product does what I need and appears to be exceptional.

This product keeps the differential cool!

Fresh axle build for a bronco project. The 9” and D44 both got the good stuff. I’ll see how they look in 500 miles.

Used the 75W-140 in the rear of my F-250 SD (came with a New Banks diff cover as a package deal). I loved the ease and convenience of not having to hand-pump the fluid into the diff. The Easy pack was GREAT and no spills, no mess! So, when it came time to do the front diff, you bet I found the 80W-90 easy pack for the front also. Highly recommend the AMS oil for the packaging and of course, the reputation for lubrication products.

So far so good. The flexible bag was easy to handle and the Ams Oil videos were helpful.

Good product..highly recommend

This bag makes filling a diff much easier And with no mess...

Meet the OEM Specs. I'm happy of the quality and product longitivity
