Gas Stations near SDSU — College Area

Where's the cheapest gas near SDSU?

Gas prices in the College Area follow San Diego's broader market, with station-to-station spreads of $0.10 to $0.30 per gallon on any given day. The 10 stations in the neighborhood split between El Cajon Boulevard near campus in 92115 and Mission Gorge Road through Grantville in 92120.

Independent and discount-brand stations on El Cajon Boulevard typically price a few cents below the name-brand stations on Mission Gorge — a pattern that holds across most San Diego neighborhoods where brand stations cluster near freeway access. Apps like GasBuddy show real-time pricing across all 10 stations if you want to confirm before driving.

Grantville stations near the I-8 on-ramp tend to price slightly higher than the mid-corridor stations further from the freeway — the convenience premium for drivers topping off on their way to the interstate.

Are there gas stations on Mission Gorge Road?

Mission Gorge Road through Grantville has stations positioned near the I-8 interchange and further north toward Mission Trails Regional Park. Drivers headed to Cowles Mountain or Mission Trails can fuel up on the south end of Mission Gorge before the road narrows into the park approach.

The Grantville stations sit alongside the area's auto repair shops and tire dealers, so topping off while dropping a car for service is a single-trip errand.

What gas stations near SDSU are open 24 hours?

Several stations on El Cajon Boulevard and Mission Gorge Road operate around the clock — the major-brand stations with convenience stores are the most likely to keep 24-hour pumps active. Check individual listings for current hours, since some stations lock pumps overnight even if the convenience store stays open.

For late-night fills near campus, El Cajon Boulevard stations in 92115 are the closest options. Grantville stations serve the overnight crowd coming off the I-8 eastbound.

Is there a gas station near SDSU with a car wash?

Some of the larger stations on both corridors include automated car wash bays attached to the fuel operation — the kind where you get a wash code on your fuel receipt above a certain gallon threshold. These attached washes handle basic exterior rinses and are faster than the standalone car wash options in the neighborhood.

For a more thorough wash or a detail, the College Area's dedicated car washes and auto detailing shops handle the deeper cleaning that a gas-station wash can't match.

For additional automotive services beyond fuel, La Mesa's automotive corridor east on the I-8 and Santee's Mission Gorge extension both serve College Area residents heading out of the neighborhood.
