A data base of cleaning methods, can you imagine? I think everyone has thier own methods, the list would go on forever! I had been running Byron fuels 15% (because that's what was available), but now that the good LHS closed down and the owner moved to AZ, I'm stuck with a car shop that keeps a few plane things in stock. The fuel (which I haven't ran yet) is sold in square metal cans and mixed by some company in San Antonio. (still 15% nitro, 20% oil) If not for that, I'd have stuck with Byron forever, because it's what worked and was available.
