Be careful. Make absolutely sure that any commercial fuels you buy do not have any biodiesel additives. It will clog the injectors and you will be stranded right there. The repairs will cost about 5 grand and are not under the warranty................
Apart from a big road trip I took (Midwest,Canada) I buy all my fuel at one of three nearby stations...Hess,Gulf and Sunoco.And on the road trip I stuck with major brands just off the Interstate.
