Customer Ratings & Reviews

I've done my research and Amsoil almost always outshines the competition. I'm not a lab scientist so I can't speak to the lubrication properties of the oil. What I can testify to is the ease and simplicity of using Amsoil's Easy Pack. I've changed lube in many differentials over the years. It's normally a drawn-out process or using fluid transfer pumps that result in a mess to clean up. Not so with easy-pack! Just cut the end off the filling spout and squeeze. The spout is long enough that it stays in the filling port and the collapsable bag ensures all the lube is placed in the differential. I lost zero product during the whole process and I had no pump to clean up either. Thanks Amsoil, well done!

Love amsoil. Run their products in both trucks with no issues.

Easy to use bottle fluid out performs stock

No need to say how good the oil is, that goes without saying, but I’m blown away by the easy pack. I’ve never found it so easy to fill a diff. If access is an issue give the easy pack a try. No mess, no fussing.

So far so good in my Jeeps front Dana 44 Differential. I've read good things about this American Lube and bad about that other brand....so here we are

Good rear end lube. I like the easy to fill packaging that cuts down on spillage.

I've used Amsoil 75W140 in every 4wd I've ever owned. This is tuff, slippery stuff. The new squeezable package is great, so much easier than using bottles.

Makes a difference when towing and off road. No more more burnt clutch smell!

Soft package makes it easy to maneuver. Quality seem nice, but time will tell.

Did my first diff lube change on my new to me 2017 GMC Sierra 1500 truck. Based on the tons of online and video recommendations, I decided to try Amsoil. The best part was the pouch bags for easy dispensing. Wish all manufacturers did this. Look forward to the next easy diff lube change in 40K miles. Thanks for the excellent products.

I replaced my differential oil with Amsoil. I have used Amsoil in my Cummins for years with no problems. I have done research on oils and Amsoil is the best out there for all their products. Amsoil is awesome.

Use this in a cocktail mix in my manual transmission.

It feels like I have new bearings in my 4wd cummins

Love the squeeze bottle very easy to use!

This is a great product, have used Amsoil gear lube since 1972. It has heat & friction reducing qualities that petroleum based products don't have. I can give you examples, if you wish, at another time.

This stuff is awesome. Hard to actually measure the lubricant qualities, but it's worth it just for the Easy Pack containers. SO much easier to use, especially in tight locations.

i really like this new packing, so much easier to use when i'm filling up my primary fluid

I like the fact that it does not have the friction additive so if your vehicle uses an LSD you can add that to the mix

Excellent product which I had no doubt. No more gear noise

Very easy to use, can reuse it by filling and squeezing over again
