rydogg 186 #1 Posted March 23, 2013 I've been looking for a 80 gallon compressor to run my air tools and a future sandblaster and paint gun, I came across this one for a good price and picked it up...it is a 1970 2 stage Champion R-15 pump that is supposed to be 18 to 23 cfm and only turn between 600-800 rpm I was trying to avoid one of the newer ones that are noisy and non rebuildable, the company that made this one is still in business so I can still get a rebuild kit when needed, these are supposed to get 50,000 hours before rebuild so I shouldn't need one anytime soon since it was just used in a homeowners shop. My question is what type of oil should I use standard or synthetic or does it not make a big difference? I will be using this in my shop where the temps can range from 0 degrees to 90 degrees so what viscosity should be used? I have heard of people using Mobil 1 synthetic or transmission fluid since it's easy to find but is it ok to use? Share this post Link to post Share on other sites
squonk 44,038 #2 Posted March 23, 2013 I can't tell what's best but I've been using Amsoil synthetic air compressor oil in my cheapie CH 6hp vertical for at least 10 years. It stands in an unheated shop and it never fails to stat up no matter how cold it gets. When I first got it using regular compressor oil it would trip out when it got close to zero.

rydogg 186 #3 Posted March 23, 2013 I have a little twin tank emglo compressor that will trip the the onboard breaker when I try to start in in cold weather so I will probably change that oil out too. I did some research into the amsoil synthetic and it looks like a good oil to use I contacted a dealer and ordered 3 quarts of the 30/40 weight for the summer if I have any problems in the winter they have a 20 weight that I can use. Thanks for the info. Share this post Link to post Share on other sites
