...and in Europe, diesel is not taxed as high as gasoline, making it cheaper per gallon. We don't have that arrangement in the US because liberals have already raised fuel taxes on diesels to "punish" those evil trucks out there.
Therefore, any benefit we might get from diesel technology will be offset by the costs of the fuel.
“Therefore, any benefit we might get from diesel technology will be offset by the costs of the fuel.”
I have observed the retail price of diesel range from 90% to 110% of the price of premium gasoline.
If mileage is better with diesel by 25% to 35% it is more correct math wise to say the improved mileage may be PARTLY offset by higher fuel price. (As contrasted with saying ANY benefit)
And if our local representatives at the federal and state level felt voter pressure, perhaps tax inequalities could be adjusted.
Until recent years, diesel was lower in price in my state, rather than being higher.
I think your blanket contention is open to change.
