We mix it with super unleaded to boost octane (50/50). Opinions may differ though '74 Challenger..9.46 @ 145.9 1/4, 6.001 @ 118 1/8 so far. 4023lb !!! # N/A, Marsh performance 655ci, Indy Maxx, T/R, Indy 600-13 X's, Street legal, pump gas, full interior, Cal-Tracs, mufflers, 3:73's and real 10.5 radials. 9.51 @ 142.4 1/4, 6.003 @ 114 1/8 with our old mule KB, 572-13, 580 wedge.

I don't know if all aviation fuel is even the same though? www.dunnuckracing.com

I think this is one of the reasons he offers many different race fuels,not all engines need the slow burn,but still need high octane. www.dunnuckracing.com

Running more octane than you need can produce less power. high octane makes it more resistant to detonation/ spontaneous ignition. high octane fuel can make more power- dynos don't lie. much. Up to the point of your engines need for octane. After that point the power can deteriorate and using more octane than the engine wants is a waste of money. The burn rate of high octane is slower than lower octane. This the reason for more advance needed to get a complete burn for the power stroke of the engine.

No harm at all except to a car running o2's... 106 octane fuel... Per the guy that delivers it to our local airport... 2011 RAM3500 1967 Fastback Barracuda with some go fast goodies.

There is no highway tax on it, most airports would not let you drive a car up to the pump since that would be illegal. Get in gas cans and tell them it is for a float plane. The down side is that it is usually more money than auto gas due to the limited competition . There isn't an airport on every corner to compete with.

First, it's called 100LL. 100 being minimum octane rating. Second, LL means low lead which is a misnomer, it is actually a very high lead content which explains white exhaust pipes on airplanes(and the O2 comment above). There is no such thing as unleaded av gas in the US.....yet. The EPA is in the process of outlawing the tetra ethyl lead which will change a fuel that has not changed since Jimmy Doolittle got it produced. Av gas will soon be about 84? octane without lead but some other lubricating agents added. You can probably run it without problems if you don't mind the lead but keep it in mind while reading a plug.
