Geez, I got a lot of questions today...
I was in the States a week ago, and will be there again when most of you read this.
As a VW TDI owner, I always check the price of Diesel fuel when I'm down there, and am quite amazed at how expensive it is right now.
Regular gasoline varies a LOT down there, from about $1.70 in the Detroit area to $2.35 or so in Los Angeles, two burgs I happen to have been in recently.
But Diesel fuel is almost fifty percent more expensive.
In Canada, it is also pricier but by nowhere near as much - more like a quarter to a third.
I know Diesel fuel comes from the same 'fraction' of a barrel of crude as jet fuel and home heating oil. Also, that crude from various sources has different amounts of each 'fraction'.
Both gasoline and Diesel are still cheaper in the US than here. Americans whine constantly about their fuel pricing - they have no idea how good they have it down there.
I just wonder why the differential between gasoline and Diesel is so much larger in the States?
