$5.86 / gal Regular average · 25 locations
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: $5.896/gal, 26 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.

A valley separated by hills and passes
Simi Valley lies in southeastern Ventura County, surrounded by the Santa Susana Mountains and Simi Hills, west of the San Fernando Valley. Its setting matters when comparing a local stop with a station on the other side of a pass. A short map distance can conceal a very different road journey.
Plan the valley approach
For a visit to the Ronald Reagan Presidential Library or another local destination, use the actual address. For onward travel toward Los Angeles, keep that endpoint in the route. Compare the complete detour rather than assuming a neighboring valley's lower average is an accessible local offer.

Catalog locations and recent price observations are different measures. Records here use the Simi Valley city address label; this is not a census of every station within the municipal boundary. Separately named neighborhoods may appear on their own pages.
Store, food and opening-hours information is not yet recorded for this sample.
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.

Why your route still matters
