And using propane usually gums up peoples guns because they don't add in the right amount of oil or they do it to fequently and/or not often enough. I use mine alot and just because of the cost I use propane. And that is the only reason. And periodically put in a shot of Green gas to finish off a magazine before storage. But if I had a TM I would probably use the green gas.
Just my 2 cents worth.
