When I was younger I used to put 109 Octane Fuel in my high performance ford car. I used to get the fuel from a Shell gas station that had 1 special pump boasting 109 Octane. they said it was "airplane fuel".
What the hell was this, and what did it do to the performance?
I know anything higher than 93 is wasted.. but what was the deal? This is when I was younger and had testosterone coming ouf of my ears.

Higher octane fuels are used for racing engines. If you use too low of octane the valves will chatter and the engine will sound like it is about to fall apart.On the other hand if you use too much of this 109 octane on a "regular engine" you will harm the oxygen sensors among other electric devices. Addind a little like one gallon to every ten tanks will keep your injectors clean!

Aviation fuel is formulated to avoid vapor lock. (Nothing like having your airplane engine go "cough, put-uhhh" at 10,000 feet!) Other than usually having at least a little lead in it, it's not much different from regular fuel. I use it in my GS455 Buick when I go to the dragstrip, and want to dial up the advance without detonation. I buy AV-Gas, as it's called, because it works as well, for less than the the racing fuel they sell at the track.

back in the 60s and 70s cars had higher compression and with carbs and point ignition would ping and knock....New cars are designed better and most dont need hi octane
