I used to buy Amoco Premium Diesel in Rocky Mount (East of Raleigh) at the corner of Winstead Ave. and Winstead Rd. If I'm not mistaken, Premium Diesel was also carried at the Texaco right across the street. The problem with any fuel in Rocky Mount is the price.. just down the road in Wilson, diesel was 5 cents cheaper (than the lowest price diesel in RM) PER GALLON at a major truck stop. I don't know if Amoco in RM still carries premium or not since I moved away. I use RedLine religiously so haven't thought much about premium diesel but am highly interested in what your test results show. Keep us informed.
