O-235-L2C (I've installed the Lycoming high compression pistons so I need 100 octane to keep from burning holes in them). >From experience, I can tell you that the quality of what you get from a service station pump can and does vary all over the map. Some may be good enough to feed a low compression (high detonation margin) aircraft engine - but don't count on it! Case in point: While recently trailering my '64 Porsche to my current place of residence in Northern Idaho from southern California, I filled up my GMC Yukon somewhere in Oregon and could hardly keep it running. Within 30 minutes of the fill-up, I could hear distinct "pinging" (car-talk for detonation) even when I wasn't pulling a hill. (this in a big 351 V-8 that requires only 87 octane "regular"). It got progressively worse as I dipped further into the fuel from that latest fill-up. I stopped at a local GMC dealer and the mechanic diagnosed the problem - lousy fuel. He said they had seen this quite a bit lately - especially when the prices had shot up around the country. Figured the suppliers were dumping anything that would dissolve into their product. Long story short, after draining all but a few gallons of the stuff and filling with Premium go-juice, the problem went away - so it wasn't anything wrong with the engine, just real bad gas. There's no guarantee that the suppliers don't do that with any of their grades of fuel - so if you want to test your luck at altitude (or worse, at take-off) try a load of "mogas" in your Lycoming or Continental. And good luck!
