In Romania, 1 liter of gas is about 7 Lei (Lions) or about 1.4 U.S.D. Since 1 U.S. Gallon = 3.78 Liters, the price will be around 5.92 U.S.D. Still cheaper then in Filnad I see.
But it's annoying to see how in crowded Bucharest people do use a car a lot and they complain about gas and electricity prices. Use less the car, use more the electricity.
There where days when gas (not much Diesel back then - probably just a few "Mercedes" cars, the rest, only big vehicles) was cheap. But ther wheren't many cars back then and Romania still had a lot of oil.
