How we compare prices

Regular gasoline only. We compare the city average today with its average yesterday and on the same date last month. Each average uses the available stations at that time, with prices no more than 36 hours old. The mix of stations and payment conditions can change, so this is an indicative city trend.

Yesterday: Oct 21, 2026: $6.225/gal, 16 locations. Last month: Sep 22, 2026: 0 locations. Cutoffs use the same local time in California; a shorter month uses its last day. Monthly comparisons need at least 3 stations on each date; daily comparisons need 12. Past averages are reconstructed from recorded observations.

Missing details mean unknown information, not that a service is absent. Recorded amenities and hours can change. Known restricted sites are excluded from this catalog count; access at other sites may still be unconfirmed. Check the individual location before traveling.
