Will, the Rockett Fuel 100 is real unleaded fuel. When it applies to race fuel, do not let octane numbers dictate the fuel you use; take a close look at the spec sheets for the fuels and you will see what I am saying. To give you a clue, look at the specific gravity of the different fuels. NHRA tests all the fuels at Divisional and National events for specific gravity; they have a fuel specific gravity for some classes.
For the professional classes, they only allow specific VP fuels due to the fact that VP pays lots of $$$ to NHRA to be NHRA'* Fuel. They did this to keep the competion out.
The best additive for your fuel is Nitropropane; it bumps the oxygen content in the fuel.. NHRA does not allow it because I have seen cars gain 2/10th'* of a second and at least 2 to 4 MPH down the track.
Two of the best mixes are sold by Klotz:
I try to stay away from aviation gas as much as I can; AVGAS has aromatics in it'* composition that are added to help the AVGAS to burn at high altitude that may not work at sea level and can actually slow down your car.
Also, when you purchase a gas can, never use a clear one and if you do, keep it always in the shade and cool place. The sun and heat will deteriorate the fuel when stored in a clear container. I always use red or blue only.
