Probably the biggest issue with ethanol is that it hardens accelerator pumps.If you drive the car every day you probably wont have an issue,but if you let the car sit,you will definatly get a flat spot on acceleration. This is why it is such a big problem for the boating and small engine industy because those engines sit for weeks at a time without. It will corrode the insde of carbs and gas tanks if it sits since it absorbs water and then lets it corrode the metal around it. If you use the car all the time it is less of an issue because the gas is always fresh.
