Cotulla drivers: AAA says Texas regular $3.42, diesel $4.48 (July 13) — down vs. yesterday

As of July 13, 2026, AAA’s latest Texas average price check (statewide benchmark) shows regular unleaded at $3.4210 per gallon, down from $3.4300 yesterday. Diesel is listed at $4.4790 per gallon, down from $4.4810.

Why this matters in Cotulla: AAA’s table is a Texas statewide average, not a Cotulla pump-by-pump number—so your local price can be higher or lower depending on the station you use.

AAA: Regular and diesel compared with week, month, and year ago

Regular unleaded (Texas statewide average): Up versus week ago ($3.3080), down versus month ago ($3.5400), and still well above year ago ($2.7730).

Diesel (Texas statewide average): Up versus week ago ($4.1870), down versus month ago ($4.6430), and still much higher than year ago ($3.2000).

EIA weekly context: Texas gasoline vs. U.S. diesel

The federal EIA retail series uses a different dataset than AAA, so it won’t match day-for-day. But in the latest week shown by EIA—week ending July 6, 2026—EIA lists Texas weekly retail gasoline (including taxes) at $3.393 per gallon, and U.S. diesel (all types, including taxes) at $4.578 per gallon.

What it means locally for commuters and fuel-heavy work

A drop from one day to the next can look small at the pump, but it adds up fast across the kinds of trips Cotulla-area drivers make every week.

• Commuters: If you refuel frequently, even small daily moves can affect weekly totals—especially during longer hot-weather driving stretches.
• Contractors and service fleets: Diesel swings tend to show up quickly when crews are refueling multiple vehicles on the same routes.
• Delivery and route drivers: Your biggest lever is where you consistently buy—local station pricing can diverge from statewide averages.
• Agriculture and ranch operations: Diesel-powered equipment and farm logistics keep fuel budgets sensitive to sustained price levels.

If you’re trying to cut costs, don’t just watch averages—compare the prices you’re actually paying and keep an eye on the “month ago” and “year ago” comparisons when budgeting.
