You al are living in Paradise
In Holland 1 liter cost 1.25 EUR = 1.67697 USD. Howmuch liter is a gallon
1 gallon is equivalent to about 3.8 liters
So, you'd be paying about $4.73 euros per gallon, or, in US dollars, that's $6.34 per gallon.
That sounds about right for europe, they pay a lot more for gasoline than we do.
This means, to fill your tank, it would cost you 56.76 euros, or in US dollars, you'd be paying $76.13 in US currency (by the current exchange rate)
now THAT'S expensive!
