Will pre-heated gasoline burn better?

No it sounds dangerous

NO, the cooler the air/fluid mixture that enters the combustion chamber, the better. from a physics standpoint the cooler these two are, the more dense they are, which means the more of them you can stuff into the combustion chamber, and conversely, the more air and fuel you have in the chamber when you ignite it, obviously the bigger the bang you'll get from the explosion. which then equals more power from each rotation of the engine.

also, there is no safe way to heat gasoline without a large risk of blowing yourself to bits if the gasoline gets in contact with your heating element. add to that the fact that most cars have a 17+ gallon fuel tank, you'd be sitting on top of a very nice sized BOMB.

entertain this idea no further....

No, by heating it you are lowering the density so you are using slightly less fuel and making less power, racers use cold cans and cold air induction to make the most power. In the old days cars had an intake snorkel which you could manually turn to draw warm air off the engine exhaust manifold, this was used in really cold weather with carbureted engines.

No!!!! Don't even go there....Gasoline FUMES burn, not the liquid! Diesel burns better warmed up because diesel LIQUID FUEL actually burns. The volatile component of gasoline is "Gas"-oline.

No!! Its not a diesel. You need a good mixture of cold gas and warm air. A turbo on the engine will force warm air into the intake, and ive known people to place a small gas can in a cooller full of ice on mudboggers.

No. It's like asking if a match will light better in 110 degrees than in 50 degrees. Doesn't make a difference.

no, cooler gas has more bang for the buck..

race cars have run the fuel lines through ice cans for years

No, actually cold gas burns better.

NO, that only works for diesel.

no you will blow up..# 2 fuel oil is not even preheated...
