The real determinant is the
difference between gasoline & diesel prices. As long as the difference remains fairly constant, the savings will remain fairly constant. My last set of calculations indicated that diesel would cost about two cents (
) less per mile than gasoline, assuming the predicted fuel economy & price premium for the diesel engine. Over a 100K mile ownership, the diesel would save $2000 compared with gasoline, but the diesel engine would make the truck cost $3000-4000 more. So you'd have to drive the vehicle 150-200K miles to break even. Although that's well within the normal range for both gas & diesel engines, most owners trade well before that point...
