Add kerosene to your gas to stave off detonation & advance your timing now for more ponys!?!?

Kerosene is really Jet Fuel that hasn't been tested or additized to meet alll jet fuel specifications. It is produced in low volumes as it is not used for many things anymore. But Kerosene, Jet, and diesel fuel are all similar Distillate Fuels with boiling ranges starting just above the top of the gasoline range. I can give details, but few would care about those. AvGas (Aviation Gasoline) is a very specific set of fuels and some can be used in non-highway (e.g., Racing) applicaitons as the contain lead and have a higher overall octane rating. There are a number of grades of AvGas and some would not be good for racing. Avoid the Unleaded (UL) grades. There are a few Low Lead grades (90/96LL and 100LL), but the hightest octance grades are 100/130 (Green) and 115/145 (Purple). AvGas is color coaded so a pilot can know immediately what fuel was loaded on the plane as detonation in flight is slightly more serious an issue than on the ground. Many aircraft engines are turbocharged or even supercharged for performance at altitude and need the high octane fuel for detonation resistance.
Some WWII fighters ran 80 to 90 inches of manifold boost to make power at 32,000 feet. The Curtis-Wright Double Wasp used in the HellCat, Corsair., Thunderbolt and other planes made 2800 HP at altitude making these planes fly over 400 MPH and then they were competitive or dominant over fighters from Japan or Germany. They ran on 150 octane fuel to make that power reliably and had methanol/water injection for use under Military Power (read dog fighting).
