Haya in Ingland, why, we gotta pay up $6.50 a gallon. ~ Capfka

Mind you, we should remember that the gallon in the UK is about 20% larger than the US gallon:

"The United States standardised on a close approximation to the old wine gallon. It was at one time defined as the volume of a cylinder 6 inches long and 7 inches in diameter, or 230.907 cubic inches. Today, however, the gallon is 231 in³ exactly. Thus 10 US gallons equals 8.327 Imperial gallons. The Imperial gallon is about a fifth larger than the US gallon.
Both the Imperial and United States gallon are equal to 8 pints. However in the US a pint is 16 fluid ounces whereas an Imperial pint is 20 fluid ounces. Thus a U.S. gallon is 128 fl. oz and an Imperial gallon about 160 fl. oz. This means that A US fluid ounce is around 1.8047 cu. ins and an Imperial fl. oz is around 1.7339 cu. ins. So the US fluid ounce is actually bigger than the imperial, although the US gallon is smaller."

Got that?
