Larry mentioned that he has an in-line oiler from snap on tools. From my past experience I would recommend to anyone planning to install in in-line oiler to get a very good one. When I first purchased my compressor the salesman at harbor freight suggested that I get one and pulled one from the shelf. This unit was $2.75, I should have known better. It has a glass reservoir and the 1/4" threaded ends for your connectors. There was no way to regulate the oil and all of it dumped into my air line. I won't repeat the first 3 words that I muttered. That thing went right into the trash. I would suspect that the one that Larry has was a little more than $2.75. Since then I elected to just drop oil and will convert to the spray that Larry has mentioned.
