There is 87 Mogas, 100 Low Lead (100LL), and 130. 100LL is pretty common for the 4 and 6 cylinder general aviation aircraft (single and 2, 4, 6 seaters with one and two engines).

87 and 130 are getting less and less common. I don't think I've ever seen 130, altho my plane is placard'ed to use 100LL or 130.

Larger planes than that and you start seeing Jet A fuel used in single engine and twin turboprops, turbine, and turbofan equipped planes.

For example, in western NY, you can see prices in the Buffalo area for Jet A, 100LL, and Mogas: http://www.airnav.com/fuel/local.html enter BUF or KBUF. You can try other areas also, such as LAX (Los Angeles), FTW (Fort Worth), JFK, STL (St Louis).
