Customer Ratings & Reviews

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

If I Could Ride Inside My Gear Case I Could Tell You More.😁 But We Know The Results Would Be 5 ⭐️!!

Very high quality, as you would expect from amsoil. Not really a fan of the pour spout bag, I have a little hand pump into a funnel that I prefer but they do work if you have room. Amsoil is the only product I use in my vehicles, they are too expensive to go cheap oils and lubes on.

Definitely less friction I always gain at least another mpg in my diesel pickups .

Received quickly and worked great

Love the product works perfectly better than other brands

I recently swapped my OE diff fluids with this stuff. I have a 2018 Taco TRD OR 4x4. This stuff really did make a difference. The ADD actuates much faster and smoother now and my gas mileage increased. The bags make refills a breeze. I love this stuff.

Classic Amsoil in a really handy package. Made refilling the differential absolutely simple with no mess.

Ease of use! Really impressed with these bags over bottles. Filling the either differential was a breeze. Total game changer.

Just switched a few months ago. Time will tell but so far everything running smoothly and feels better!

Love the easy pack makes oil changes much easier than the bottle and pump.

Don't buy inferior lubricants use the Best.... AMSOIL

I have a Mercruiser Bravo outdrive rebuild shop,,I have been using severe gear 75/140 synthetic for many years in my personal boat outdrives,,and I recommend it to all my friends,, I recently removed my outdrives and refreshed them ,,preventive maintenence,, my gearsets look near new,, and they have over 500 hours on them,inside the housings were spotless clean, all bearings were perfect,,and this oil runs cooler than other oils,,

The absolute best oil to rub in your V twin trannys!!! It will quite and smooth shifting will be noticed immediately! Also when its 117 degrees out you want the best protection possible!!!

When you want the best, never let me down

I use amsoil in my diffs, trannys, and transfer cases and this stuff is the best for your diff. I've never had a failure while running amsoil.

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!
