First off, it is important to explain that when I fill up the tank the price is by the liter, not the gallon. (think 2 liter of coke and divide in half)
Here is a little math lesson...
1 liter of gasoline in the Netherlands = 1.43 euros
1 gallon on gasoline is the US = $2.59
1 euro = $1.48
4 liters = (approximately) 1 gallon.
So, if 1 liter costs 1.43 and there are 4 liters to a gallon, then 1 gallon of gas in the Netherlands would cost 5.72 euros which is about $8.50.
I am starting to bike more and more. We just bought a two seater kid trailer. Good exercise and cheaper!
