does sugar in the gas tank really destroy a motor ? theres a camero at a local garage that threw a rod out the block, and there reasoning for this is sugar in the tank.. This car is owned by a middle aged man who apparently does not drive the car hard. How the garage came to the conclusion about the sugar is also unknown. personally, I cant see it, wouldnt the sugar in the tank just disolve ? just as it would in a glass of water ? and even if it didnt disolve, wouldnt the particles be to small to cause any damage and or be trapped by the fuel/oil filters ? and if it did pass the filters, I cant see there beeing some funky chemical reaction between gas and sugar to break something down. I always thought of this to be myth anyone have facts or scientific proof on this ?
