Is cheaper gas worth the detour?
Use your tank and extra travel costs. Prices below are AAA state averages as of 2026-09-16; check the actual station prices before driving.
Extra distance and time include the return to your original route. Detour fuel uses the higher state price. Tire wear and maintenance are excluded. This estimates a price difference; it does not verify a station offer or route.
Where the $0.05 gap actually comes from
All of it is tax, and then some. The fuel itself is dearer in Georgia before tax — by $0.02 a gallon — yet it is still $0.05 cheaper at the pump, because North Carolina levies $0.07 more per gallon. Policy is doing all of the work here and overcoming a product disadvantage on the way.

Why is gas more expensive in North Carolina?
Entirely because of tax. Georgia actually pays more for the fuel itself — $0.02 a gallon more before tax — but North Carolina levies $0.07 more per gallon, which more than reverses the advantage.
Is diesel cheaper in Georgia or North Carolina?
