Chapel Hill-area gas averages $3.86; diesel reaches $5.37

The latest AAA price check puts the Durham-Chapel Hill metro average at $3.857 per gallon for regular gasoline and $5.368 for diesel. The figures are dated July 31, 2026, and represent metro averages—not the exact price at every Chapel Hill station or a city-only average.

The two fuels are moving differently. Regular gasoline rose 0.8 cents from the previous day and 0.3 cents from a week earlier. That is nearly flat week over week, but the longer comparisons are more significant: the average is up 23.6 cents from a month ago and 89 cents from a year ago.

Diesel is rising faster

Diesel reached $5.368 per gallon in the same AAA metro check, increasing 4.8 cents from the previous day and 13.8 cents from the prior week. The monthly increase was 65.7 cents, while the year-over-year increase was $1.758 per gallon.

That makes diesel the sharper cost pressure in the latest local comparison. Contractors, delivery operators, landscapers, service companies and other businesses that use diesel-powered vehicles or equipment may face more direct exposure than households that primarily buy regular gasoline. Higher fuel costs can also add pressure to delivery charges, service pricing and operating budgets, although the price data does not show how individual businesses are responding.

Regional context and local variation

The U.S. Energy Information Administration’s gasoline and diesel update provides broader regional context for the latest price movement. Those figures cover a larger Lower Atlantic area and should not be read as a competing Chapel Hill-specific average.

For commuters and households, the regular-gas trend means a typical gallon in the Durham-Chapel Hill metro costs about 90 cents more than it did a year ago, even though the latest weekly change was small. Weekend travelers may see noticeable differences from station to station, particularly when comparing locations along major routes with neighborhood stations.

Drivers should treat the AAA number as a benchmark rather than a guaranteed pump price. Individual Chapel Hill stations can be higher or lower depending on location, competition and when their prices were last updated. Comparing nearby stations before filling up may still produce meaningful savings, especially for larger vehicles or business fleets.
