I was looking at CH owners manuals recently for a new compressor that I was considering, and it recommended Mobil 1 10w-30. It was specific not to use other engine oil brands or weights. Check the CH website to download the current version of the manual for your unit - it might give you more up-to-date guidance.
It's surprising that the Amsoil guys aren't all over this thread - I think they have a compressor oil product too.
The Ingersoll Rand oil is pretty good stuff - the first winter I had my little compressor, it wouldn't start after the beginning of November because the factory fill oil was too thick. This winter I used it the whole way through with the IR oil in it. It has an 8000 hour change recommendation from Ingersoll Rand, which in my case means my children's children will have to change it again some time in summer 2110.
