Speedway Express operates the Shell-branded fuel pumps at 7594 University Avenue in La Mesa, dispensing regular, midgrade, premium, and diesel through Shell's TOP TIER-certified nitrogen-enriched additive system. Shell's nitrogen-enriched regular and midgrade grades protect fuel systems during the stop-and-go driving common on University Avenue, and the station falls within the roadside-assistance dispatch zone of AAA La Mesa Insurance and Member Services for lockout, flat-tire, and emergency-tow calls. Shell V-Power NiTRO+ is available as the premium option here, carrying a detergent package that Shell engineered in partnership with Scuderia Ferrari to withstand the higher combustion temperatures in turbocharged and direct-injection engines. The western University Avenue position places this station near the Lemon Grove border, serving cross-neighborhood commuters who fuel up before or after their east-west run toward downtown San Diego via Interstate 8. Emergency automotive lockout and key-replacement service for drivers at the pumps is handled by Bonnie & Clyde Emergency Lock And Key Service, whose mobile technicians program transponder and smart-key fobs for vehicles from most major manufacturers. Shell V-Power NiTRO+ formulates its premium grade with seven times the EPA's LAC (Lowest Addable Concentration) detergent baseline, engineering the polyetheramine molecule to survive 500-degree-plus combustion-chamber temperatures in turbocharged GDI engines and recirculate through the PCV system to scrub carbon from intake-valve backsides that port injection cannot reach.
