Macclenny-area fuel prices: AAA Jacksonville metro regular slips; diesel edges down (July 20)

Macclenny-area Gas & Diesel Watch: AAA’s Jacksonville, Florida metro pump averages (Baker County is included in the Jacksonville metro, per the county’s Comprehensive Emergency Management Plan) show regular gas easing today and diesel edging down. Regular is $3.9180/gal, down from $3.9300 yesterday; diesel is $5.2530/gal, down from $5.2570 yesterday.

Regular gas: down vs. yesterday, still well above last year

AAA Jacksonville metro regular (as of 7/20/26): $3.9180 per gallon.

That’s down from $3.9300 yesterday (7/19/26). It’s also up versus last week: $3.8150, last month: $3.6600, and a year ago: $3.0870.

Diesel: slightly lower than yesterday, but still costly

AAA Jacksonville metro diesel (as of 7/20/26): $5.2530 per gallon.

Diesel is down from $5.2570 yesterday (7/19/26). Even with that small drop, the diesel average remains up compared with last week: $4.9040, last month: $4.7830, and a year ago: $3.7020.

Why this matters locally in Macclenny and Baker County

Because diesel runs many routes and job sites, even small daily moves can matter for local budgets. For Macclenny-area commuters, the regular-gas trend is a direct driver of fill-up costs. For contractors, farmers, and delivery or freight drivers, diesel’s much higher level versus last year can still pressure operating costs—especially for businesses that refuel frequently or run equipment on tight schedules.

One important note for planning: AAA metro averages aren’t the same as any single station’s price in Macclenny. They’re a regional yardstick—use them to see whether prices are easing or tightening.

National context (EIA weekly benchmarks)

EIA’s latest weekly benchmark shows U.S. regular gasoline at $3.855 for the week ending 07/13/26, up $0.078 from the prior week. For diesel, EIA shows $4.796 for the same period, up $0.218 from the week before. These are weekly U.S. benchmarks—not a daily Macclenny estimate.

What to watch next

Next AAA check will show whether today’s down vs. yesterday moves for both regular and diesel hold—or whether prices rebound.
