Yes, the USA, the "number one" nation on earth is the only country, that still hasn't converted to the much easier metric system. Anyway, fuel in the States runs at about 2.10 US dollars per gallon for trucks and 1.70 US dollars for farm use. In 1998 I filled my pickup for 80 cents a gallon. The price has so far more than doubled within six years. That converts to 55 cents for a liter of clear diesel and 45 cents for a liter of farm diesel.
