I bought a pint (?) at Lowe's. It was specifically labeled for Air compressors. I think it was a synthetic. Before that I always use 30 weight motor oil. I bet 30 weight synthetic motor would be fine.

Regular petroleum motor oil tends to carbonize your pump's parts (piston, rings, valves) resulting in reduced CFM, more oil carryover, and longer runs to get up to set psi. This is why the quality makers (IR, Quincy, Speedair, etc) will double their pump warranties if you buy and use synthetic oil. I use IR's label but both HG and Lowes sell their own brands of the same stiff.
Depending on your use, change once or twice a year.
