So now in America diesel is more expensive to produce than gasoline.
How about in Europe? I keep reading about super advanced diesel automobiles by Honda, Volkswagen, Toyota that the European love. These cars are not sold here
Europe has a slightly higher requirement of 10 ppm, so similar or greater expenses.
I don’t know if they have applied that restriction to Gasoline yet. The US EPA is about to put it into effect, so the gasoline price will rise up like the diesel did years ago.
