*Fuel Performance Facts

I posted this on another board earlier. I find the numbers interesting.

A few weeks back I was given a copy of Grassroots Motorsports, December 2012. It contains an article titled, The Fuel Truth. They used an SCCA 1990 Miata with a 2001 long block, built by Kevin Boswell. A C Street Prepared Autocross Class car.

They tuned and dyno tested these fuels. With the following HP/Torque numbers.

Quick Trip 87 E10
135/117

Hyperfuels 93 EO No Alcohol
134/122

Quick Trip 93 E10
136/124

Shell URT 100 Racing Fuel
137/123

Shell URT 105 Racing Fuel
137/124

Hyperfuels E85 85% Ethanol Alcohol
143/128

VP M1 Racing Methanol
160/140

There were very small increases in any primary gasoline based fuels. Methanol scored the highest while E85 finished second. Which I think shows performance wise, run the lowest price fuel that works efficiently in your motor. Unless you desire to run alcohol. Higher octane fuels do increase fuel mileage.
