Shell Food Mart pairs grab-and-go convenience essentials with Shell V-Power NiTRO+ fuel at 5302 Lake Murray Boulevard near Lake Murray in La Mesa, combining a c-store, car wash bay, and three-tier fuel island at a single I-8-adjacent site. The fuel system pumps TOP TIER Detergent Gasoline in regular, midgrade, and Shell V-Power NiTRO+ Premium formulations—a certified fuel lineup designed to reduce carbon buildup, complementing the full-detail auto-care services at Soapy Joe's Car Wash on Jackson Drive. The c-store interior carries snacks, cold beverages, and a limited grocery selection, with an ATM terminal and air-and-water station rounding out the Lake Murray Boulevard service menu. The station sits at the Lake Murray Boulevard interchange with Interstate 8, capturing freeway-adjacent commuter traffic from the same automotive customer base that services vehicles at certified collision facilities like Fix Auto La Mesa. Shell's TOP TIER Detergent Gasoline certification requires a proprietary additive package across all octane grades that meets engine-deposit control standards exceeding EPA minimum requirements by a factor the program's technical committee sets annually.
