With these new computer controlled Duel Fuel systems it lets you control the IQ of the diesel on the fly all from the CNG controller.
It comes down to what you pay for CNG a gallon . Here in Boston at the street pumps its $2.69 for CNG ( I home fuel at $1.00 a GGE ) and diesel is $3.70 if you use a lot of diesel it works here.
But in the USA it can be as low as $1.25 for CNG at the pump so that makes it a no brainier.
