Really Ken, gas cost more here because of subsidies, eh. Hmmm...the Commex price is about $2.67/gallon. This price is good in Turkey, Central African Republic or US of A. Where's the subsidy? This is what people willing to pay for this plentiful commodity.
It's how it is taxed. See $3.60 gas in CA, <$3.00 in TX and whatever it is Europe.
No, Patton was not stopped because he ran out of fuel. The Supreme Allied Command decided, that it was in the best interest to allow the finite supply of fuel in Northwest Europe for Operation Market-Garden...and Patton was wily guy who never let his army totally run out of fuel. There was plenty of fuel in September 1944, there was plenty of shipping, after the Allies cleared the North Atlantic and Mediterranean in 1943 but there was not infrastructure. Cherbourg, Marseilles and Antwerp had not come on line and the Allies decided against a planned pause at the Seine to build supply dumps. See PLUTO, Normandy Beaches and Red Ball Express. Just like there is plenty of NG, Coal for cheap power generation. Your analogy is faulty.
