Ok forgive me if I sound stupid, but 100 as in 100 octane? And does avgas mean aviation fuel?
My other question would be what benefits do you want to see from running the mix? The truck is designed to be most efficient with 87 octane fuel, and increasing octane doesn't really serve much purpose, since its only benefit is the increased ability to resist premature detonation, which these motors shouldn't have a problem with in stock form...

I wouldn't recommend it. Dont know what additives are in it and how it will reach with your fuel system. Could cause leaks are ruin the injectors.
Not to mention you would not see any gains from it because the computer wouldn't compensate for the additional octane.

If it causes damages i dont want to do it.

Yeah I don't think it would be worth the risk. Not sure how lead would effect things like the catalytic converters either. Can you just sell it to a local airport?
I certainly would think about it first. The LL stands for Low Lead. This would not be good for a catalytic converter and probably a few other fuel system parts. In very low doses of say 5 to 10 percent may not harm the engine as fast or as serious for an emergency maybe as long as it is an old engine.
The fuel should be able to be sold after quality testing to a avgas vendor. If the fuel is known to be contaminated beyond filtering capabilities it can be sold to a recycler of used oils and fuel. Aircraft fuel can be contaminated easily often particularly true turbine fuel known as Jet fuel. It is not unheard of a whole tanker to be refused and sold as bulk oil for a furnace operation.
So you have 422 gallons of possibly expensive avgas or as cheaper bulk oil at market price.

Not suggesting that you specifically are confused, but just as a matter of safety:
Avgas is NOT the same thing as Jet-A, and should not be confused.
Avgas is high-octane leaded gasoline, while Jet-A (aviation turbine fuel) is essentially kerosene.
Given the massively different flashpoints, one should not consider utilizing something like 100LL as a fuel oil for a furnace.

DON'T DO IT!!!!!!!!!!!!
The lead in the fuel would DESTROY your cats! For those of us old enough to remember leaded fuels, one tank of leaded gas would burn out the cat.
As far as the octane rating, 100LL is rated 100 octane at like 7000 feet. The way av gas is rated is totally different than consumer gasolines. So basically at sea level your av gas is only about 90 octane. You will not see any performance difference. If anything, you will lose power and economy due to your low compression factory motor.
I used to be a fuel truck mechanic at my local airport. I have run hundreds of gallons of av gas in my '79 F-250. No cats, no fuel injection, no computer. It runs fine in the old rigs but you could not make me pour a single gallon into my Expy. The savings on the free gas would be a fraction of the cost to fix/replace what it destroys in a new rig.

sell it to a race track or team out there

Old hot rodders used to use stuff like that in high compression or blown applications to reduce knock and ping. Modern computer controlled engines won't benefit from it all.
Now, if you have an 11 to 1 big block in your truck, then go for it.

Not confused. Did not say Avgas and Jet A were the same. Industrial bulk waste fuel furnaces burn a blend of any type of fuel and waste oils including all grades Avgas, Jet A, JP-4, 5, 6 and basically any other flammable liquid. Pointed out that aviation fuel is easily contaminated and routinely used in that and many other manners like asphalt production and some types of hybrid plastics. Normally once there is biological growth in aviation fuels it is condemned and considered beyond filtering, separating capabilities of most users.
