Are 130 and 145 Octane AvGas fuels still available in the USA?

If not what do the guys who fly the WWII heavy iron do for a substitute fuel? What about the Reno racers ?

I've looked at the "fuels available" at several airports around the country and haven't found them listed. Most list Jet A and 100 AND 100LL and that's about it. Oh yeah - some list MoGas as well.

100/130 avgas, now commonly called Avgas 100, is dyed green. It contains a maximum of 4 g of lead per US gallon (1.1 g/l). 100LL has replaced 100/130 in most places, but Avgas 100/130 is still sold in Australia and New Zealand.[dubious – discuss]
[edit] 91/96 & 115/145

In the past other grades were also available particularly for military use, such as avgas 115/145 (dyed purple) and 91/96 (dyed brown). Limited batches of 115/145, commonly called Avgas 115, are produced for special events such as unlimited air races; in the past 115/145 was used as the primary fuel for radial engines

100LL is on it's way out as well...apparently Lycoming is trying to lead the push to find a suitable replacement. California is on the verge of outlawing 100LL, which would be bad for GA

Not as bad a 4 grams of lead per gallon going into the atmosphere. Sorry, but GA can change just like the car driver had to.

The problem for aircraft is a little more complicated, given the nature of aircraft engines, being lightweight and air cooled. Many of the higher performance piston engines used in GA today require the use of lead, or the engines will burn out. While major research is being done into a solution, to legislate avgas out of existence at this point would be premature.

Given the current situation of GA, it would be disasterous to force a change right now. Too many older planes require leaded fuel to be safe, and if they go, so do so many pilots and all the jobs that go to support them. A lot of more recent planes are switching to diesel (which can run Jet-A as well), but just up and killing off 100LL would probably kill the general aviation industry Sad
