About this item
AMSOIL PC Series Synthetic Compressor Oil is a premium, long-life lubricant engineered to improve compressor efficiency and reduce maintenance costs. It is formulated with the highest quality, thermally stable synthetic base oils and premium non-detergent additives to provide maximum protection in high-temperature applications. It can last up to 8,000 hours, significantly reducing the downtime and waste-oil disposal costs associated with more frequent oil changes.
Amsoil makes products much better than other oil manufacturers I’ve tested them all and Amsoil always performs best and comes out on top. I bought this compressor oil for my harbor freight air compressor. This should help it last for 20 years or longer
Bottom Line
Yes, I would recommend this to a friend.

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.
