Drivers in Germany are facing higher fuel costs as reported by the ADAC, with petrol prices rising to an average of 1.672 euros per liter, a 2.2 cent increase from September. Diesel saw a sharper rise, averaging 1.571 euros, up 2.7 cents. Factors contributing to these increases include rising crude oil prices, which surpassed $80 per barrel in October, and a weaker euro against the dollar. The ADAC advises consumers to compare prices before refueling amid these fluctuations.
