Customer Ratings & Reviews

I bought oil for two compressors, one is my new 7.5 HP that's awesome and a 40 yr. old 1hp I use that had started slowing down like it was about to seize. I put Amsoil ISO 100 SAE 30/40 in and it literally brought it back from the dead, I thought I was gonna have to scrap it but it runs like brand new now, quieter and no stalling at all. It never had oil this good, Great job, I'm very impressed with your products.

We are using this oil in our purchased used IR SS3 compressor. This machine did not appear to be abused too much but seemed to have lacked maintenance. I noticed the oil dislodging some dirt so we will keep an eye on it

Been running this stuff in my compressors for years. To date I've never had a compressor head failure of any kind.

1992 60gal air compressor working good as it should using this oil

This is a very good oil that I use in place of the manufacture recommended one and it does a better job and allows my compressor to run cooler and quieter than before. great oil!!

I use this in my Dewalt 30 gallon compressor. It works great and exceeds manufacturers specifications.

Used since 2016. Same viscosity as tuthills more expensive oil. Wish it was tinted and not clear to help with checking oil levels in my small sight glasses and came in the quart easy packs like some gear oils do

No problems got what I paid for.

WORKS WELL IN OLDER MACHINES (30 YR OLD CHAMPIONS) EVEN THOUGHT ITS FORMULATED FOR NEWER TECH

Faster recovery of air from my 15yr old compressor. I was using just a conventional synthetic. Proper oil now.

I used this oil as a wipe-down in newly refinished and dry cylinders in a 2 stage pump. The drag was reduced and almost eliminated. In the crankcase, rod bearings are quiet and the rings are sealing well resulting in fast pressure build even though it is a 20 weight oil. I'm impressed.

Que ce soit pour l'industrie ou pour votre machinerie à la maison ou votre voiture, rien n'égale Amsoil, ne vous faite pas avoir avec les marques commerciales qui vous disent 100% synthétique, c'est une pur Arnaque, la vraie de vraie, c'est AMSOIL !!!!!

Great oil for my Ingersoll Rand compressor and a lot cheaper. Can't go wrong with Amsoil.

Great product

Best compressor oil ive used.

Amsoil compressor oil used in a freshly built compressor, very tight. After initial start up compressor runs until it hits 150 psi then shuts off, you could put your hand on the cylinder that was barely warm.

My air compressor had a had times starting in cold Temps. I added this oil and the compressor fires right up when cold. I wasn't surprised, everything I own has AMS!

Anything that is Amsoil is awesome

Like i said perfect for my big shop air compressor, been using it for years, change it after winter every year, no issues never sludging up. Actually looked good changing old oil, but in NC the moisture pprobably gets into the oil over time, so best to be safe and change it even if it looks good still. Its worth every penny!
