Customer Ratings & Reviews

AMSOIL Severe 75W-90 is phenomenal gear oil. I’ve ran it in my ‘01 4Runner for years now with great results, and when drained from the rear differential, it still looks like new! I’ll never use any other gear oil than this one.

Used it in my 2016 ram 2500 6.7 Cummins rear and front differential. So far it’s working great!

Love the easy fill pouches! Hands down.

I changed the gear oil in my front and rear differential and noticed that when I drove there was way less resistance due to the heavy oil I was using

Very easy to put it in.

Smooth like Butta. Gotta getcha some of this and put it in !!!

This has to be the easiest Diff fluid change ever. Pull fill plug, pull drain plug (yes, in that order) cut the top of the spout off and squeeze the bag to fill untill it's full. Simple, not messy, easy. Amsoil is the best.

Best gear oil on the market. Not sold on the bag yet, the end cap would be the only thing I would change. It did not fit in the areas I needed (Can-Am outlander Gear box/Diff).

It’s amsoil this thing worked great

Easy to use and put in. I seem to gain some fuel mileage. I did this on my 2002&2003 Tahoe. I did change all fluids with Amsoil products.

Excellent product

This along with the limited slip additive was exactly what my 2002 Explorer called for and differential is running smoothly and quietly.

Great product and might switch over my engine oil to amoils

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.
