I've read a few places that Ethanol shelf life is measured in weeks. I drive my car year round, but for those that store their cars over the winter, would this be a problem?
Even regular gas isn't stable forever. I suppose filling the tank with winter blend prior to storage is a safe bet.

!WHAT!
Or are there some stations in NJ that don't use 10% ethanol yet? I only noticed the sticker on BP, Amoco, Sunoco, Garden State Fuels, and Wawa stations. I did not see on Exxon, Shell, Mobil, Citco, or Lukoil, but I was talking to someone at an Exxon station and he said their tanks had E10, though there was no sticker on the pump specifying 10% ethanol.
