On any given Sunday, You can see the posers lining up at the Castrol Purple pump for a tank of 115 for the ride home from Summit Point. (W.VA. racetrack) You can tell them that it makes no difference even with their little powercommander installed, but they won't listen. If you really want an increase in power that you can feel in your buttdyno, with a relatively stock engine, run it on Coleman Camp fuel, but don't come crying to me when you burn a hole in your piston(did this years ago on a camping trip when we ran out of fuel and had nothing but coleman on hand). White fuel is basically gasoline with no additive packages in it, i.e. no burn modifiers and octane/cetane additives. Years ago, one of the drag racing ricer's on CRX.org was running regular low test with 10% by volume toluene mixed in to boost octane. He claimed no problems other than melting fuel system components if you went to 15-20% by volume. I don't think you would want to run that in our babies though.
