Chevron's ExtraMile convenience store at 1666 First Avenue serves downtown San Diego's Cortez Hill neighborhood with fuel, grab-and-go meals, and packaged goods alongside the Chevron pump island. The station operates as G&M Oil Company franchise unit No. 35 under the Chevron brand and doubles as a Pearson Fuels E85 flex-fuel dispensing site, a dual-fuel infrastructure that complements the mechanical services at Downtown San Diego Auto Repair nearby. ExtraMile's in-store format stocks fresh pastries, gourmet grab-and-go meal kits, energy drinks, craft beer, and locally roasted coffee through the chain's curated beverage program. The First Avenue location delivers via Uber Eats and Postmates for the surrounding Cortez Hill residential towers and Bankers Hill condominiums, extending the convenience footprint beyond the pump-island walkup. The same morning-commute corridor feeds specialty coffee demand at roasters like Achilles Coffee Roasters @ The Rey in the adjacent downtown blocks. The fuel island dispenses Chevron Techron-formulated gasoline in 87, 89, and 91 octane grades plus E85 ethanol-blend flex fuel through dedicated pumps certified under California Air Resources Board vapor-recovery standards.
