Supposedly, any vehicle built in the last 10 years or so will do fine on a 10% ethanol blend fuel. As Scott said, it's the off-road equipment that is having the most problems. Hardly a week goes by where a salesman doesn't drop by and hand me a bottle of some type of fuel treatment, with instructions to try it and let him/her know if it works. The manufacturers don't have the answer either, and they're grasping at straws.
I tell all of my customers.. stick with premium fuel, and try and get gas with no alcohol in it. Also, regularly running the equipment, even during the off-season, will help greatly.
