Mobil in downtown San Diego pumps ExxonMobil Synergy-branded gasoline at 2045 Pacific Highway, sharing the lot with a full-service car wash operation on the waterfront-adjacent stretch between the SAN airport and Harbor Drive. The fuel island stocks regular, midgrade, premium, and Synergy diesel grades alongside a compressed-air station, and the co-located full-service car wash funnels customers toward the paint-correction and ceramic-coating tier that GTR Mobile Detailing Inc delivers by appointment across downtown. The Synergy fuel line uses a proprietary detergent-additive package designed to clean intake valves and reduce engine deposits over repeated fill-ups, a chemistry differentiator within the ExxonMobil brand portfolio. The Pacific Highway lot sits midway between the airport rental-car return corridor and the Harbor Drive waterfront, catching both commuter and tourist traffic flowing along the waterfront. Rental-car drivers returning vehicles to the airport corridor route past the Pacific Highway pumps for pre-return refueling, a traffic pattern that feeds the same stretch where Hertz Car Rental - San Diego Downtown operates its Middletown counter. The diesel pump serves commercial box trucks and delivery vehicles cycling through the Pacific Highway logistics corridor, a fuel grade that several smaller downtown stations have dropped from their islands.
