In addition to Cowboy Bill's comment, it also depends on the vehicle and the type of AvGas. Note that the lead additives used in AvGas are highly toxic even in small quantities.
Avgas 80/87 is probably okay to use in your average car from an octane point of view. It's red in color.
Avgas100/130 is very high octane. If you have winters where you live, your car will not start in the winter with this fuel in it.
Avgas 100LL is also a high octane fuel and will cause difficulties in cold weather.
It should also be noted that ALL Avgas has lead levels in the gasoline that is higher than that of Mogas by a factor of hundreds, or even a thousand, which is a major contributing factor to the illegality of it automobile usage. Lead levels on that scale are actually good for the valves and internal parts of your engine, but will clog fuel filters pretty quickly in your average fuel injected car.

Lots more octane than you need. Aircraft engines are low speed (2100 rpm approx.) large displacement high compression engines requiring high octane (slow burn) fuel. Automobile engines are higher rpm (5000 to 6000), smaller displacement, lower compression engines requiring lower octane (faster burn) to run optimally. I don't think your ignition advance curve could properly adjust to the higher octane in order to benefit from it's slow burn characteristics. You would be wasting a lot of fuel/energy out the exhaust pipe. If you had a high performance (high compression) racing engine, you could benefit from avgas.

mix it 25 percent avgas to regular fuel and you will see a performance gain. but running it straight will deffinatly cause problems unless you mess with the timing and such. i use to do it on my older carburated vehicles in the 80's to get more power. i wouldnt know or suggest doing it in a newer fuel injected vehicle unless you dont mind rebuilding your engine after a couple of mistakes

If you got a hopped up engine, you may need the higher octane. If you're talking about a regular engine, you will burn the valves.

It's illegal. (does not meet CAPA certifications for automotive fuels)
