Well said, Jay! Just a few more comments: 1. Generally speaking, for most given areas, certainly my area, all mogas comes from the same pipeline. (Large metro areas may have several sources.) The only difference is the additive which amounts to about a 1/2 pint per 1000 gals. So the "brand" does not make any difference with repect to the fuel itself. The brand name additive does vary. The additive is what allows the big boys to say "ours is better". As you say, turn over is a better criteria than brand. 2. In the late '70's (or there abouts), I recall the FAA issued a letter advising pilots of 80 oct. engine equiped planes to only burn 100LL when necessary to get to the next 80 oct. fuel stop. They even listed the negative effects of 100LL in an engine designed for 80 oct fuel. 3. To verify that there has NEVER been an accident or incident attributed to auto fuel in a plane, simply do a search on the NTSB web site. As Friday would say, "Just the facts Mam, just the facts". 4. Quite frankly, one does not need to be a chemist or a pet. engineer to logically deduce that if one 0-540 engine will run successfully on auto fuel, they all (80 oct engines) will run on it. Gee, I'll bet this is how Peterson and EAA got the STC. As you point out and see #3 above, if there has never been a recorded accident or incident attributed to auto fuel, how can one argue that it is "unsafe"! Poppycock!!! I too, bet the FAA would be Johnny on the spot recalling all auto fuel STCs in the event auto fuel was the culprit for an engine failure.. 5. I have no gas leaks in my plane, so the only time I smell it is when I fuel. Of course, I also smell it when I fuel my cars, cycles and mowers. No issue for me. Besides, isn't lead extremly toxic? Isn't that why it was taken out of fuel and paint? Check out an Avweb artical by John Deakin, "Lead in the Hogwash". So, whether you are a right brain or a left brain person, happy flying. See you at Oshkosh.
