compressor in cold weather?

Page 2 of 2  


Just a thought - what about air tool oil or electric motor oil? Would guess any lightweight straight oil would do. -Dan

I bought non-detergent oil at HD as instructions say DO NOT use detergent.

We use Mobil 1 synthetic motor oil in ours.
Available at most any gas station.

That is true for older cars without rebuilt engines. If it's rebuilt, start and stay with detergent oil. The problem is in an old engine they are counting on a buildup of sludge and varnish, which actually helps the rings seal and give it good compression. Change to detergent oil and it cleans away the sludge, reducing compression, then it doesn't run as well.

Motor oils usually contain detergent. And detergent makes it easier for the oil to absorb water. This isn't a problem in cars, where it gets good and hot each time it's run. But in a cold application like a compressor, it can absorb and hold the water.

If it's small enough and you have the space you could put it in a heated area during cold weather. If that's not practical, check the owners manual for cold weather oil recommendations. IME most compressors call for straight 30 weight oil, often non-detergent.
