NO!!! Don’t do it! 100 octane low lead for aircraft is made for aircraft not cars. The low lead title is very misleading. What they actually mean by this is that it is a low lead fuel if you were running it in an aircraft. My sister’s boyfriend is an aircraft mechanic and he says that 100 low lead has 3 times the lead content of a leaded automotive fuel.
Besides our cars are made to run on unleaded fuel only. If you were to actually run leaded fuel you would foul up the O2 sensors along with others.
The reason that they can run it and not worry about it fouling up the engine is because they regularly tear down and rebuild there engines after XXXX hours of time on them.

Re: gasoline
No, you should not do it, for more reasons than there is time to list. But in short, here are some reasons.
The design of an aircraft engine and the conditions under which it operates warrant the use of lead as an anti-detonation additive. There are no catalytic converters, no O2 sensors or anything else that would be damaged by lead. Even the spark plugs are made in such a way that the residual lead from the combustion process is scavenged to prevent lead fouling.
Your engine was designed for unleaded fuel. And, if your engine does not have some serious modifications (and is in a good state of repair) you should not have detonation concerns. If you are un-modded, why spend the extra money? If your engine does not require the higher octane by design, you will receive no benefit by buying the expensive stuff. If you are heavily modded, use unleaded racing fuel or an octane booster. It's going to be cheaper in the long run because the lead will definately cause damage to your cats, plugs, and sensors, ultimately making your car's performance reduced.
I can vouch for the facts cited by KrazyKamaro. I'm a FAA licensed aircraft mechanic.
