[Healeys] FW: Air Fuel Meters easy to find?>

[Bob Spidell]

The most commonly available avgas is 100LL.  It's 100 octane lean and 110 rich.  

The "LL" stands for low-lead, but it's only relative.  130 octane avgas is no longer available but had, I believe, 3grams of elemental lead per liter.  The "LL" has, I believe, 2g/l ... still quite a bit of lead.  Large displacement/high HP aircraft engines cannot survive on currently available unleaded fuel ... bound to be a problem for the light aircraft industry someday.  Even the (until recently available) 80-octane avgas had quite a bit of lead in it.

Gary, you can get unleaded 100-octane VP racing fuel at a gas station in Los Altos.
