Corzette Posted November 16, 2003 Share Posted November 16, 2003 I have heard that if I mix 1 gallon of racing Alchohol with 10 gallons of High Octane Gas I can raise my Octane level to around 105+. Is this safe for aluminum heads and is it safe in general? Anyone ever do this? CZ Quote Link to comment Share on other sites More sharing options...
randy 77zt Posted November 17, 2003 Share Posted November 17, 2003 an alcohol engine is jetted with double the size carb jets than a gas motor.engine will run lean.plus alcohol attracts water and condensates in your crankcase.it swells fuel lines.avoid this stuff-its for race cars that are torn down alot.run good gas and build a not to high compression engine.some guys shoot nitrous with alcohol or nitrous with an auxilary gastank filled with race gas.if you have a good cooling system.aluminum heads,and watch your ignition advance curve you can run about 10 to 1.

dot Posted November 17, 2003 Share Posted November 17, 2003 Up here the oil companies put up to 10% alcohol in the gas in winter to eliminate the condensation in the gas. It boils at a much lower temp causing problems in the summer. Cheers...:::Glenn Quote Link to comment Share on other sites More sharing options...
JMortensen Posted November 17, 2003 Share Posted November 17, 2003 Try searching for tolulene or toluol, we had this discussion about a month ago. Here's the quick version. You can mix race gas with regular, run toluol or xylol (aka tolulene or xylene) mixed with gas to get your octane up. Toluol is already in your gas from the pump, but it is 114 octane so you can mix 1 gal to 5 gallons of gas to get about 96 octane. Xylol is 118 octane. I've run race gas, xylol, and toluol all with good results. Supposedly you can run up to 35% xylol or toluol with no ill effects.
