I drive a 20 year old Z-car. In the past 18 months I've had to have the injectors replaced, the fuel lines replaced, and the tank dropped and drained. All ethanol related problems. I run premium fuel, keep the tank topped off, and use a fuel stabilizer, but that is not enough...
Had the same issues with my 1990 jeep and the generator on the old RV. After spending almost $1000 in repairs on the gen I ran only non-ethanol and stabilizer......never had another problem. Same for the jeep, have not had any issue since keeping away from the ethanol.
Was also told that it is not good for my 05 durango.
