G & M Food Mart is a San Carlos gas station in San Diego at 8780 Lake Murray Boulevard, where the 92119 commercial strip runs between the lake's recreation shoreline and the residential grid south of Navajo Road. The station pumps regular and premium gasoline under an unbranded canopy, keeping per-gallon pricing independent of major-brand contract floors that inflate costs at branded competitors along the same corridor. Curbside air pumps let drivers top off tire pressure after fueling, catching the same low-PSI issues that bring San Carlos vehicles into Aero Auto Repair for full brake and suspension diagnostics farther south on Lake Murray Boulevard. A walk-in convenience store behind the register carries cold beverages, packaged snacks, tobacco products, and basic automotive supplies including windshield washer fluid and motor oil. The exterior propane exchange rack holds standard 20-pound tanks for backyard grills and patio heaters, and the self-serve car wash bay handles a quick exterior rinse without requiring an appointment. Lake Murray draws weekend joggers, anglers, and rowing crews year-round, and the station's position at the boulevard's midpoint makes it a natural refueling stop between the lake and the Navajo Road shopping cluster. San Carlos residents who bundle auto coverage through Alex Peterson-Cross - State Farm Insurance Agent in the same neighborhood can add roadside-assistance riders that cover emergency fuel delivery to the Lake Murray Boulevard addresses G & M already serves. G & M accepts credit cards, debit cards, and NFC mobile payments at the pump, and four dual-sided pump positions under the canopy clear a six-car queue without stacking vehicles into the travel lane.
