Fontana Gas and Diesel Prices Rise as Diesel Tops $7 at One Station
AAA’s latest San Bernardino market check puts regular gas at $5.616 and diesel at $6.992, while one Fontana station lists diesel at $7.199.
Regular gasoline and diesel both moved higher in the latest AAA price check serving Fontana. Regular gas reached $5.616 per gallon, while diesel rose to $6.992 in the San Bernardino market.
AAA’s figures are dated August 1, 2026. Regular gasoline increased 0.5 cent from the previous day, and diesel rose 0.3 cent. The San Bernardino figures provide regional price context for Fontana; they are not a precise citywide average for every station in the city.
Diesel is rising faster over the longer trend
Compared with a week earlier, regular gasoline was up 3.2 cents per gallon, while diesel was up 10.7 cents. Over the month, regular gas increased 34.8 cents, and diesel climbed 55.6 cents.
The larger diesel increase matters most for drivers and businesses that depend on diesel-powered vehicles. Delivery operators, contractors, landscapers, agricultural businesses, restaurants making supply runs and service companies may face greater fuel exposure when diesel rises, although the effect will vary by vehicle use and business costs.
One Fontana station lists diesel above $7
A 7-Eleven listing updated within 24 hours for the station at 18091 Arrow Boulevard in Fontana showed regular gasoline at $5.499 per gallon and diesel at $7.199.
That individual station snapshot placed regular gas below the San Bernardino market average and diesel above it. It should not be treated as representative of all Fontana stations. Prices can vary by location, brand, fuel supply and payment method.
For households, higher regular-gas prices can add pressure to commuting and weekend-travel budgets. Diesel costs can also affect delivery charges, contractor estimates, restaurant supply trips and service-call expenses. Commuters and weekend travelers may want to compare nearby stations before filling up, while commercial drivers may benefit from checking fleet-fuel options and routes.
