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!

I am not a scientist, and I did not do any studies, so I can only go by what claims have been made of synthetic lubricants. I am hopeful that this product will help my compressor to last longer, but how can I really know for certain. I am hopeful that it will help. I will say the AMSOIL company did process and ship my order quickly. So, I am happy about that. Maybe in the future, the consumer will see real data to confirm whether synthetic lubricants actually warrant the higher prices. I see much marketing claims but is it entirely accurate? I do remain hopeful. Thank You AMSOIL.

It is good stuff, it works. My compressors like it, and they appear to run better.

Started using this in my compressor 4-5 years ago. Compressor is smoother and runs cooler than ever before.

Used on My Speed air compressor. Runs well with this oil.

I got the to change the oil in my portable Ingersoll Rand compressor and the 80gal 5hp IR compressor. everything still works like new! I just ordered some for a friend to use in his Quincy 80gal compressor. Its a great oil, and see no reason to use anything else!

I replaced the break-in oil in my Home Depot Husky compressor when new. 15 years later I decided it was time to change it again. The oil drain was only slightly discolored which is normal and probably could have been left in for life. There were no metallic particles visible in the oil. AMSOIL makes the best lubrication products for my equipment. If you want it to last forever, use AMSOIL.

Michigan - gets hot and cold - 3 compressors in unheated / uncooled area. Synthetic should handle range better. Overdue to be changed anyway. Extra cost over time is minor.

I have used Amsoil Compressor oil from day one. My compressor supplies air to a large "Abrasive" blaster as well as a 15,ooo pound four post lift and various other pieces of equipment. It has to run every day all day and it will with Amsoil!

It may be a bit early to tell because I just used this product for the first time a month ago. The oil was clear which will make it easy to see through the sight glass if it gets burned within a year.

I was running my compressor about 1/3 low in oil for six years because I misread the fill instructions. This oil kept it from burning up or having any damage to it. Great stuff even in the winter.

I love this stuff. Recently changed out the original oil in my Craftsman air compressor with this Amsoil. Man the compressor runs so much better and it fills up the air tank a lot faster as well. I love all Amsoil products and cannot recommend them enough to everyone. Amsoil is the best oil on planet earth period!

AMSOIL is a superior synthetic

Haven't put it in the machine yet. Amsoil is the only lubricant I use on all my equipment. Has never failed me.

Old Sears Roebuck 25 gal compressor runs great with this oil

Great complement oil to my screw compressor in the summer time, we throw 3Ltrs of this one to keep viscosity while it run under higher summer temps.

Great screw compressor oil. Keep internals clean and lubricated at all times, and all temperatures year round. We change ours 4 times a year and oil most of the time comes out fairly clean with minimal burn color. Just do your changes as frequent as you can, and your compressor will be very happy with the quality of this oil. I don't like super long periods of time while oil changes, but that's me, I like to take care of my equipment since they are not cheap at all to buy, and wont be cheap to repair if screws and internals go bad. It is cheaper and safer to change your oil with quality stuff like Amsoil, than pay thousands on parts and labor to fix it due to negligence.
