Finding cheap gas in San Diego (92115)
San Diego State University sets the rhythm of this ZIP, and the College Area around it pulls a young, car-light crowd that still needs to fill up between classes and commutes. El Cajon Boulevard and College Avenue frame the neighborhood and carry most of its gas stations.
College Avenue near the campus and the long run of El Cajon Boulevard are your best corridors. The stations here compete for student and faculty traffic plus the steady stream of drivers using these arterials as alternatives to Interstate 8, which sits just to the north of the area.
Speaking of I-8, the stations positioned right at the College Avenue and Fairmount Avenue interchanges price for freeway convenience. For a routine fill, the stations deeper into the College Area retail strip along El Cajon Boulevard usually shade a little cheaper than the ramp-side spots.

How to save more on gas in San Diego

2. Fill up early in the week
Stations often raise prices Thursday for weekend demand. Fill up Monday through Wednesday to avoid the lift.
3. Keep tires properly inflated
Properly inflated tires improve fuel economy by up to 3 percent at current prices. Check pressure once a month.
4. Check back tomorrow
Prices can shift 10-20 cents overnight during volatile markets. A quick check before you leave home avoids paying yesterday’s spike.

About gas prices in California
California has the highest gas taxes in the nation at roughly 60 cents per gallon when you combine the state excise tax with the cap-and-trade program and underground storage fee. The state requires a special CARB-formulated fuel that only a handful of in-state refineries can produce, so a single refinery outage can spike prices statewide within 48 hours. Costco, Sam's Club, and Arco are typically the cheapest across Los Angeles, San Francisco, San Diego, and Sacramento metros, while Chevron, Shell, and 76 dominate freeway exits. Stations along Interstate 5 and US 101 commonly run 10 to 20 cents higher than equivalent stations a mile off the freeway.
