Regular gasoline in Jacksonville averages $4.36 per gallon, while Florida diesel reaches a historical high of $6.35.

Regular gasoline in Jacksonville averages $4.36 per gallon as of Friday. This figure represents a four-cent increase from Thursday’s average of $4.32. Drivers filling a standard 15-gallon tank now spend $65.25. The local price sits slightly above the Florida statewide average of $4.33. The national average remains higher at $4.47 per gallon. These figures come from data reported by GN auto markets/energy: gasoline prices.

Florida diesel prices reached a record high of $6.35 per gallon on Friday. This marks a significant jump from the annual average of $3.66. The increase amounts to $2.69 more per gallon compared to last year. For a 20-gallon purchase, the cost difference is $53.80. This rise impacts commercial logistics and shipping costs directly.

Monthly Price Surge Exceeds Forty Cents

Regular gas prices in Florida have risen by approximately 41 cents over the past month. Prices moved from $3.92 a gallon to the current $4.33 average. This change costs a driver purchasing 15 gallons an additional $6.15. The increase reflects broader market pressures rather than isolated local factors.

Crude Oil Volatility Drives Costs

Elevated crude oil prices contribute to the recent fuel cost increases. Volatility surrounding the Strait of Hormuz also factors into the pricing. These geopolitical and supply-side elements influence global energy markets. They subsequently affect retail prices at the pump across the United States.

Diesel Hikes Threaten Supply Chains

Higher diesel prices increase the operating costs for commercial trucks. These vehicles transport goods across the region. Businesses face pressure to manage these rising expenses. Some may pass these costs along to consumers. Local residents express concern that this will raise the price of everyday goods.
