Customer Ratings & Reviews

The transmission is working great again.

definitely recommend using. could tell the difference in my jeep.

Great product and packaging. Watched lots of review videos and AMSOIL stuff is always at the top of the pack. Highly recommend.

All good! Thanks

I bought a vehicle that had a rear end that was going a lot of bearing noise. I put Amsoil in it and I ran it for three years before I was able to save up enough money to get it replaced.

Reporting facts, you decide. Used AMSOIL 75W90 for gear oil change. Changed original factory fill toyota highlander oil in transfer case and differential at 60k miles. Did it on warm gear boxes just after the trip to make sure it would fully drain and particles (if any) are suspended. Magnets on oil plugs contained some shavings, but oil looked pretty clean and clear. After a months and about 200 miles I had a reason to drain this oil in the same manner. To my surprise oil contained metal silvery particles in it and looked a bit different than it was when new just a month ago. Magnets on both plugs again contained metal particles, but very little compared to first time. Wiped with napkin and it did show black traces of metals. At this point I am not sure what to think of the reasons for oil/magnets to contain wear out materials at such a low miles.

Use it on Toyota for front and rear differentials. Great gear oil.

Changed my diff gear oil at about 80,000 mile Oil had a very slight hint of Brown probably could’ve got another 50-80k but I was putting on a new Yukon diff cover. Amsoil is the best out there hands down Amsoil is absolutely the best

This definitely one of if not best on market. 50 thousand on last change still looked great. Amsoil is awesome stuff!

I recently purchased a pickup with 100,000 miles Unsure of service work done I elected to put this product in my front and rear differentials Just going off others experience and the amsoil reputation i feel i made a good choice and should be good for a long while

Makes for an easy and spill-proof installation, plus an easy clean-up.

Changed the oil in the Power Transfer Unit in my Ford Edge. Definitely made an immediate difference in quieting it down. The easy poor packaging made refilling this awkwardly placed fill plug accessible without a pump, great end user experience. No long-term review since it's only been a few weeks since this product was used.

Best diff lube for the new Bronco.

Love ordering from Amsoil, always ease to find and quick shipping. THANK YOU;}

I was able to change my differential fluid in about 30min on jacks stands thanks to the Easy-Pack. Very smart packaging and quality product as always from Amsoil.

I am using this for extreme drag racing. Its used in the differential in my Jeep Trackhawk. It seems to work well. I like that the traction control additive in it already. The easy pack packaging is handy. ONE full pack is just the right amount. Its best not to fill too much. If your racing, change diff oil with your oil changes, until it stays clear.

Used it on a 2019 Mazda 3 to replace the transfer case and rear differential fluid. And vehicle feels a lot better!! I only use Amsoil for my vehicle.

I’ve been a mechanic for 35 years.. I have used basically every oil on the planet.. I put this fluid in the front and rear differential of my wife’s 2017 Toyota forerunner. After a few days she said, what did you do to my car? It seems more quiet. Just for total discretion. I also used signature motor oil when I did the oil change also. I believe Amsoil is the superior product than any of the big companies out there if my wife noticed that’s all I needed to know.

Easy package to get anywhere. I added a screw on nozzle and forced all the fluid into my quichchange rear end in a matter of seconds.

Excellent product. Drained and filled front, and rear differential and transfer case and all is good. Be sure to buy the correct pump for the wide threaded neck otherwise will take more time and effort using a squeeze bottle.
