Fontana gas prices
$5.78 / gal Regular average · 51 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: $5.813/gal, 51 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.

Several freeway corridors in one city
.jpg){kind=link}
Fontana is a trucking and logistics center crossed by Interstate 10 and State Route 210, with Interstate 15 passing through its northwestern part. A fuel stop on one corridor may be inconvenient from another. Commercial activity also makes it important to distinguish a public-car stop from restricted or fleet-oriented access.
Stay with the corridor you are using
Enter the complete route and check the chosen station's access and payment terms. A low diesel or fleet transaction price should not be interpreted as a gasoline offer for every driver. Compare the relevant fuel grade before deciding whether to leave your current freeway.

Catalog locations and recent price observations are different measures. Records here use the Fontana 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.
