I'm sorry but here in France we pay gasoline in liter, not in gallon (and I forgot the convertion between liter and U.S. gallon
)
Here we had two ways: normal gasoline with more or less octan level (called here as "essence", then "super", and "super sans plomb" (without lead in it). After we had gazole, for diesel thermodynamic cycle engines.
Gazole was always cheapest than normal gasoline, it was always so the prices of diesel cars were a bit higher than normal ones to make a economic marge.
But since two or three weeks ago, gazole's price became higher than gasoline! (about more than 1,50 Euro a liter, I let you make the convert in USD per gallon)
Our small fleet of fishing boats, dependings most of diesel engines, could difficily handle this situation as it is seems (fishing became not rentable here now...). They made strike and asked to the governement to do something.
But here, the fuel is overtaxed by government, so I don't know what will happen.
It is odd here that, even if the prices are high, and as we have extended common transports networks (but they still have many defaults, this is not the subject), that you can hear all the cars running as more as ever...
Personnaly don't have one, I have transportation from my job, but if want to go on holiday I have to pay train (railroad), but I feel if I had a car I couldn't manage the gasoline bill, even if here we have relatively low fuel consomption cars.
So I expect I could have given info about gasoline situation in my country.
