Taxes or subsidies determine the price of gas in different countries differently. Like in Venezuela one can get a gallon of gas with 15 cents only. But in Germany it costs $5.53. With the gas filled in your vehicle with $20, you can go to a different distance if you start in different countries.
You can cover 127 miles in Germany, the least distance covered comparatively. In Japan it will be 147 miles. In India the vehicle can go to 213 miles way ahead of Germany. In US it can go to 342 miles and in China it will be at 385 miles away. In the oil producing country Saudi Arabia, the vehicle will cover the distance of 771 miles. Now it is the turn of Venezuela, the largest oil exporting country, the vehicle filled with the gas of $20 will go surprisingly to 4624 miles.
