Hmm... in that case, do you know what accounts for the 14whp gain that was achieved from the XXX Oxygenated Race Fuel?

I think this is more of a terminology issue than anything else.

To me, oxygenated is meant in the government regulation sense in which oxygenation is used to control emissions and reduce pollution.

Maybe they use "Oxygenated" differently because it sounds better and sells more gas but really what they are selling is a blended fuel that has a higher energy content and is more appropriate for racing and most likely not street legal. This could count for the documented Hp gains. JP-5 or aviation fuel has a higher energy content than standard gasoline. I'm sure it would boost horsepower as well but i'm sure you would have some serious knock.

Psh Home made race gas(via your local chemical wholesaler or work hookup) One gallon of Propylene oxide(Oxygenator in the nitromethane kind of way)which EXPENSIVE, one gallon of Tolulene (sherwin williams for $14 bucks, omit if not advancing timing or increasing boost/compression) to ten gallons of premium gas. The propylene oxide may be federally controlled now (F**King anti-terrorist laws) but it's good for about a 6% boost in power, and the tolulene is a knock inhibitor that bumps the octane rating of the fuel to around 110-115 letting you crank the boost. You will go through A LOT of fuel but it's power in a can.

Very few of the octane boosters at the advance auto work the one that worked the best was the NOS octane booster in the box used 2-3 per tank and it would let you run a 100 octane map. The ones that say they will raise your octane 6 points mean .6 octane hence 6 "points." The gallon of tolulene beats all in that department ~7 full numbers for $14 and ~14 for $28. Careful though the PO and Tolulene will take their toll on plastics if you use them continously so i'd save it for track days and flush it out with 93 at the end.

Wow! Rep for that knowledge. Very informative
