Customer Ratings & Reviews

Been using this gear oil for 20+ yrs now, always a great product and bag bottles are easier to get in tight places.

For quite a number of years I have exclusively used Amsoil products to put into all 4 of my vehicles. I have 3 all-wheel-drives and a 4x4 pickup and I use the 75W-90 Severe Gear Lube for the transfer cases and differentials and it has always put my mind at ease. I don't plan on using anything else but Amsoil...ever!

Great Product , Great Service , Great Price . Thank You Very Much .

Very easy to put the oil in a transfer case with no space using this package.

Did a full replacement of fluids (drain and fill) with amsoil products. So diff, transfer case and atf on 2010 Toyota RAV4 V6. Products seem top notch. Everything running optimally. Very pleased in the performance of these products. If I don’t use factory fluid they have to be the best, hence Amsoil!

Very high quality oil

I did a lot of research and decided the AMSOIL products was what I needed due to my hauling a heavy camper often.

Use this in a Subaru rear differential. Now it seems like when I kick off the cruise control, I coast a lot farther then before. Also, my magnetic drain plug had a lot less goop and crud with this over the factory gear oil

I've used this lube in the front axle of numerous vehicles. I use 4wd a good bit so a durable oil is important. It always performs well.

Do heavy towing. Want the best protection possible

Great lube for 08 LS 460. No problems whatsoever

Smooths shifting on manual gear box of Tacoma in any cold or hot conditions ! Love it .

This is the last oil you will need for gears!

This product is great, no question about that. The only reason for the 4 stars and not 5 stars is 2 of the 4 containers the threads on the cap would not allow the filler cap to fit so I had to use a funnel and was a pain and not as clean as the first two!

This product is not designed to be used for filling a Can Am front gear box. This product needs two hands to handle due to its floppy nature. More was wasted than able to get in the restricted area even with tube attached. Sorry I bought this.
