In Finland, Diesel is noticeably cheaper than gas (currently below €1.20 per liter vs gas ~€1.45) and there's an offset in the yearly "diesel powered vehicle" tax that is around €350-€400 a year, depending on weight. That offset is easily countered with the Diesel engines outputing better mileage. I drove a 1988 diesel Mercedes for a year. For a fair sized sedan and for its age, it traveled with 5.5 L/100 km, or 42 miles per US gallon. I bought a newer Toyota roughly in the same size class, slightly smaller, and it needs 6.7 liters per 100 km (35 mi/g). I was saving nearly €700 a year by driving an arguably nicer car (heavier, larger, better isolation). Too bad I had to wreck it.
