Customer Ratings & Reviews

Easy to use in hard/accessible places and squeezable. Also can be reused by filling up again.

I love the easy pack, it makes putting the oil in the differential a breeze.

The age old battle of the bottles funnels and tubing is solved with this bag! My rear end oil swap took little to no effort to swap. Grab a bag and just go!

I had put a Banks Diff cover on the rear end of my 2018 GMC 3500. I originally purchased 4 quart as that is what AMSoil said I needed. It was not quiet enough so I had to purchase an extra quart to top off my rear end fill. This is a great product and the love the packaging

As with all of their oils this stuff is top notch. Love that it’s a 75W-110 since synthetic 75W-90s and 80W-90s tend to have a little too much slipperiness for some gear driven limited slip differentials like the Detroit TrueTrac. It actually calls for 80W-90 conventional but so far this stuff has worked like a dream. Will definitely buy again

After reading all the positive reviews about amsoil products I decided to give some a try myself. I am frequently towing well over my trucks factory capacity. Severe gear was a must try! Immediately after changing my rear differential oil I noticed my 1 ton pick up seemed to roll down the road with less drag. I also noticed half a mile to the gallon improvement in fuel economy. Doesn't sound like much but boy does it add up with fuel prices the way they are today.

Been using this in my 2002 S2000 rear diff for years... Great stuff!

I have a 5 speed manual. I used to have to press the clutch in multiple times to get in to go into revere and first. Now it glides right in. Literally created from the gods.

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.
