Asking because I may not understand "winter blend" correctly. My knowledge, to date, is that refineries will switch to a winter formula around this time of year, and that formula includes lower boiling point hydrocarbons as well as oxygenators.
Since I can still readily purchase E0 gasoline in my state, then the winter blend of it may have ethanol added in order to make it work during cold weather months. The problem is going to be knowing if ethanol is the oxygenator added in my area. Seems like an easy business decision for the suppliers, though, since ethanol is readily available for mixing.
Right now the price differential, per gallon, is around +$0.25 for E0 over E10.
So in summary, I guess my question can be boiled down to:
If winter blend E0 is actually E5, is it still worth buying over E10?
(and a bonus question - Does winter blend E10 remain at most 10% ethanol or do they have to add even more ethanol in order to make it winter compatible, thus making it E12 or E15?)
