Now that ALL pump gas will contain ethanol in the near future, what do you think will be the effect on the fuel seals and components of vintage cars? I believe modern cars are made to resist the harmful effects of alcohol, but I always heard NEVER to put "gasohol" in older cars. Up until now, I have tried to avoid any station that references alcohol content even though in modern cars it should not be an issue. If I had a vintage car I would be very concerned. Forgive me if this has been posted before, I could not find it in reference to older cars.
