There's a 53p per liter fuel duty (recently down from 58p) and the normal 20 percent VAT, so yes, taxes are pretty high on fuel. The fuel duty alone comes out to about $2.43 per gallon. However, if you do the math on it, gas would be fairly expensive even without it. (In fact, I have a tax exempt fuel card, so I will ultimately pay the AAFES rate, which is currently $4.199 per gallon. In total, I'll pay $65.83 for that tank instead of $122.63, which is the price shown converted from £. Still high but not quite as big of a kick in the ***.) I don't hear Brits complain about it though. They complain about fuel prices in general from time to time (though far more often about heating oil than petrol), but I don't hear them say anything about this huge surcharge that their government imposes on it. They just don't buy anywhere near as much petrol as Americans do, so it impacts them far less.
