Heck if I know
So my father just got an 05 duramax loaded ext cab with 12k miles 4x4. Its not a cummins but Im just glad he saw the light about driving a diesel. But he raised a good question that I didnt know the answer to. We were talking about fuel and how atleast in NY the dont make off road diesel anymore that I can find. Just on road and kero. he said that back when he sold fuel years and years ago #2 heating oil was the same as off road diesel fuel but it didnt have the same taxes that off road had. Curious if his memory serves him right. And if so I going to get an aux tank for the truck and keep that full of off road. Anyone deal with fuel other then fueling up at the pumps???
