Compressor oil

I have a farm and commercial woodlots for lumber. Both our maintenance shops have large air compressors to run air tools for work on heavy trucks and equipment. One shop also has a large blast cabinet. Just like their gear lube, AMSOIL compressor oil keeps things running notably cooler. Especially during long run times.

Great product that we have used for several years in our Quincy Compressors!!! Would recommend this product to anyone interested in buying a product for their own compressors!! Great company to work with!!! Highly recommend this product!!
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.
Bottom Line
Yes, I would recommend this to a friend.

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.
Bottom Line
Yes, I would recommend this to a friend.
