I am so glad that I get to pay American prices when I gas up here in Germany because of an agreement with the US military and ESSO. I can only use the ESSO gas stations or the on post gas stations though. I accidentally lost my fuel ration card which I need to get the cheaper gas (not pay the German prices), fortunately it was found and I will have it back next week when it is mailed up from another military installation that I was at a few weeks ago.
Anyhow...
To make it through the next few days until I have my card back, I went to a local German gas station and just put 20 Euros worth of gas in my car. I do not even remember how much I paid but that 20 Euros ($25.14) only put a quarter of a tank of gas in my Jeep!
If it were not for being able to pay the American prices, I would not be able to afford a Jeep over here, with it taking 80 Euros ($100.56) to fill up the tank. It normally only costs me about $54 to fill up my tank because I pay the American prices.
