I always fill up at the Quality Mart just before you make the right on to 12. Once you get South diesel is significantly more expensive. There are quite a few places to buy highway diesel down there. In a pinch I will stop at North Beach in Rodanthe and buy it there.
It's there. But little high but you have to have it. Hopefully your trip will be better than our last week trip. 12 was closed for several days. Lots of flooding. Glad to be out of there. Trapped with no power sucked
I always fuel up in Grandy on my way in. I just don't like to buy fuel from an area that floods so often. Make sure that you fuel contamination warning light is working and your water separator is drained before you go.
