Engines work by basically turning your gasoline into a fine mist of fuel and air in the engine. Then it’s ignited and exploded.

As you can imagine, putting grains of sugar in a finely controlled mixture of fuel-and-air isn’t exactly going to make the engine perform well. The sugar would also just react with the oxygen in the air at high temperature causing carbon build up (bits of burned sugar). That’s the best case scenario

Realistically it doesn’t work like that because your car has a filter to stop things like that getting into the engine in the first place. So all that’ll happen is you clog up the fuel filter and will have to change it
