FWIW, found this on Chevron's Web site after last post RE: Autogas.
"Most World War I fuels had a lean-mixture rating in the 50- to 70-octane number range..."
Hmmm...so by World War I, which began in Europe 11 years after Kittyhawk, the octane was in the 50-70 range for lean-mixture.
Chevron site is:

Still wondering what quality was available in '03 and if it was much different from the WWI 50-70 octane of 11 years later.
Curioser and curioser.

All:
The mogas discussion here gives me reason to post a subject upon which I have ruminated recently, following all the hubub last month and last year about the Centennial of Powered Flight.
What sort of gasoline would have been available to the Wright Brothers? Wouldn't think it was too sophisticated by today's standards, or even that the petroleum would have much of a gasoline market in 1903. That grew enormously within just a decade of course, but in '03, it seems the gasoline product line would have been pretty limited, without much customer demand to drive it (pun intended).
Any ideas where to track down what gasoline was available to the Wrights in late 1903 on the then-isolated North Carolina coast?
There is a ton of data, books, articles, etc., on much of what they did, but outside of mentions in several sources that the Wrights built the engine for the '03 Flyer completely from scratch and that it used gasoline, can't find much about it.
Thought maybe someone on the list might know.
regards,
Steve

I've been following the mogas issue very closely. Gasoline of today is a better quality of gas than days of past. The 'slime' or 'varnish' discussion portion of this email is correct. However, with the advent automotive fuel injected engines, gasoline has become much cleaner since manufacturers are simply reacting to the needs of sensitive automotive fuel injection systems. The fuel injection system on your Toyota Camry is infinitely more complex and sensitive to lousy gas as opposed to an aircraft engine which is based on 1940's technology. On a side note, the lead used in 100LL is quite a bit different than the type of lead used in the past. Apparently the lead in 100LL not only fouls plugs but is quite corrosive to internal engine parts. And finally, I defer to Kit (the guru of aviation) who uses mogas in his Midget Mustang. Our biggest problem is now addition ethanol in mogas. We've been purchasing our gas in Fairfield since they are exempt from the ethanol requirement.
