Hayward-Area Gas Edges Up as Diesel Climbs Faster on July 31

Regular gasoline edged higher in the latest Oakland metro price check serving Hayward, while diesel rose more sharply. AAA’s July 31, 2026, averages put regular gas at $5.654 per gallon and diesel at $6.856.

Compared with the previous daily check on July 30, regular gas increased 0.2 cents per gallon. Diesel rose 2.3 cents. The one-week comparison shows diesel moving faster as well: regular gas is up 5.1 cents from a week earlier, while diesel is up 12.2 cents.

Diesel is showing the faster increase

The separate movements matter for Hayward-area drivers because gasoline and diesel serve different parts of the local economy. Most household commuters and weekend travelers are watching the regular-gas average, which remains just above $5.65 per gallon. Diesel users are facing both a higher price and a faster weekly increase.

Diesel costs can affect delivery operators, contractors, landscapers, service companies, restaurants that rely on deliveries, and other businesses that use larger vehicles or equipment. Those costs may show up gradually through fuel surcharges, service-call pricing, delivery fees, or tighter operating margins, although the available price data does not identify a specific cause for the recent increase.

Hayward station snapshot is above the metro average

A 7-Eleven station at 700 W. A Street in Hayward listed regular gas at $5.749 per gallon and diesel at $6.949. The station page says its prices were updated within 24 hours.

That listing is a single-location snapshot, not a citywide Hayward average. It was about 9.5 cents above the Oakland metro regular-gas average and 9.3 cents above the metro diesel average in the July 31 comparison. Prices can vary by station, neighborhood, membership program, payment method, and timing, so drivers should compare nearby locations before filling up.

What Hayward drivers should watch

For households, the latest figures point to continued pressure on commuting and travel budgets. Drivers with larger tanks may feel the cost more quickly, while small businesses with frequent service calls or deliveries may be more exposed to diesel’s faster rise.

The near-term signal is whether diesel continues to widen its increase compared with regular gasoline. Regular gas has moved only slightly since the last daily check, but both fuels are higher than they were one week ago.
