Ethanol causes fuel injector problems. Since the introduction of Ethanol, the problems with gasoline are slightly different. Ethanol is hygroscopic and will absorb moisture from the atmosphere directly into the fuel molecules. Water found in gasoline sinks to the bottom of the tank.
Ethanol is created when crops such as sugar cane, maize, sorghum, wheat and other grains, or even cornstalks, fruit and vegetable waste is fermented and distilled. Ethanol blends dramatically reduce emissions of hydrocarbons.
With the introduction of Ethanol in our gasoline came a boat load of problems so to speak. The affects of Ethanol was never properly tested before its introduction, thus leaving many in various industries to foot the bill for ongoing, unnecessary and most of the time very expensive repairs. Even some aircraft using automotive based gasoline were affected.
For both retailer and end user, this is a very serious problem. More so for the end user because it is the end user that most of the time has to foot the bill for expensive fuel system and engine related repairs.
