I paid $4.39 for premium the day here in Maryland...
I'm going to Germany in four weeks for vacation. The photo below shows fuel prices there as of a few days ago. (Super E10 is a 90/10 mix of gasoline and ethanol, is what most cars use.)
Those prices are per liter, and there are 3.785 liters per gallon. The prices are in Euros, and right now, it takes $1.09 to equal 1 Euro. So...
That Super E10 is priced at $8.21 per gallon...
