Small gas-engined compressor

“I had a little FTC Decarbonizer and Cleanpower left over so I just put them both into my gas-engined compressor 5hp gas tank. I know I added too much, as the tank is only 1/2 gallon, and I put in more than suggested, so it was super concentrated. Of course, it ran like crap and a bunch of smoke came out, but not blue smoke, just black smoke. When I held a white shop rag in front of the exhaust, it was filled with chunks of soot and what looked like carbon. Could it possibly work that fast?

I just left it running, lopping along and surging, but when I came back in about 10 minutes, it was running strong and no black smoke. It was running so well, I’m thinking Can this be right? It’s filling up the 100PSI tank way better than before. It’s really just crazy that my little air compressor that would darken a white rag now has completely no smoke coming out the exhaust, how can this be? I’m literally looking all around for an exhaust leak or checking if all the oil drained out. WOW!”
