My air compressor has some difficulty starting in cold weather. I changed the oil last year and it has really been bad. Can't remember what brand the oil was, though I don't remember it being a famous name.

Any recommendations to help cold startup? How about a synthetic?

Thanks,

Charlie

How about a lamp next to the compressor to keep it warm?

I had the same trouble with mine.  It is in an unheated part of the garage.  I got Amsoil synthetic oil for air compressors and it hasn't failed yet.  I live in Maine, so yes, it do get COLD.  Tom..

I was wondering the exact same thing. Yesterday i got a new (used from my brother) big compressor. It's too big to go where the old one was so I have to put it in an unheated part of the shop. I wondered today if it would start out there O.K. As usual, RRT has the answer before i eve ask the question!!!  :D

I run Mobil-1 and when its cold out I use a magnetic plug in heater(auto zone)it sticks on the crank case and keeps it warm,i run it off a timer.
Mine is in another building as I can't stand the noise anymore.
Hope this Helps

Electric 5 horse 2 stage. Have slow blow low amperage in an old lever box just for this unit which is in the cold room in my shop. I know Amsoil makes a compressor synthetic and it sounds like that would work ok.

Russ, what grade Mobil 1?

Thanks guys.

Ok, just wanted to be sure. Some of the new compressors are specifing 10W30 motor oil, I guess because SAE30 non detergent has gotten so hard to find. I have been using 20W40 in mine, an old Dayton industrial, for several years, and it has not had any bad effects so far.

Thanks Frank. Sounds like some Trailblazer Mobil 1 will probably be just fine. Think I'll do that between other jobs later today or tomorrow.

If you plan on doing any painting with your compressor, you should be using an oil specifically made for air compressors, not engine oil. Compressor oil is formulated to be totally free of silicone. If you are using engine oil, it has a high component of silicone. This oil with silicone in it will migrate past the piston rings, and be carried in a vapur thru all of your air hose, contaminating it. When you use your compressor to paint a car, you will be plagued big time with "fish-eyes" and "craters" in your paint job, the result of silicone contamination
