Average gas prices in North Carolina have risen 0.3 cents per gallon in the last week, averaging $3.12/g today, according to GasBuddy’s survey of 6,092 stations in North Carolina. Prices in the state are 14.2 cents per gallon lower than a month ago and 86.2 cents per gallon lower than a year ago. The national average price of diesel has fallen 4.6 cents in the last week and stands at $4.34 per gallon. Of course nothing can compare to the $2/g price we paid under President Trump.
