Techron-additive gasoline from Chevron and a co-located Soapy Joe's car wash share a 0.75-acre parcel at Jackson Drive and Center Drive in La Mesa's Grossmont area, directly adjacent to Grossmont Center. The site's multi-bay auto repair shop handles emissions-related work alongside general maintenance, complementing the I-CAR Gold Class collision repair available at Caliber Collision on the same Fletcher Parkway corridor. Diesel, regular, and premium grades all carry the Techron deposit-control additive, a polyetheramine-based detergent that Chevron developed to prevent intake-valve and fuel-injector fouling in both port-injected and gasoline-direct-injection engines. Tire rotation and seasonal changeover needs round out the vehicle-maintenance corridor near Jackson Drive, with Discount Tire offering mount-and-balance service within the broader Grossmont Center trade area. Techron's PEA-based chemistry survives combustion at the temperatures present in GDI engines, allowing the detergent to cycle back through the PCV system and address carbon buildup on intake valves that port-injected fuel sprays cannot reach directly.
