AVGAS is an oxygenated fuel designed to be run at super high altitude.. not at normal driving altitude.. you CAN run it in pretty much any car but its octane (normally 100) doesn't behave exactly like 100 octane vehicle fuel would behave... the high oxygen content actually makes the fuel run slightly leaner at lower altitudes due to the ambient pressure PLUS the oxygen in the fuel
You WILL toast your O2 sensors, you WILL toast your cats.. you WILL feel a bit more power and then you WILL feel a big repair bill
I ran Avgas for a few months in my previous modded car and the net result was a cataclysmic engine failure... melted pistons... cracked block... oil in water, water in oil, cats and dogs living together... the end of life as we know it
