Refuled today and it was up at 9 USD a gallon now, was a bit of a shock so i saved the recipt, it's down below
163 USD to fill it up
(Liter price in swedish crowns * number of liters on a gallon) / swedish krowns on a USD = USD/Gallon
(15.48 * 3.785411784) / 6.44 = 9.09
1047.38 / 6.44 = 162.6 (total price for filled up tank in USD)
