West Washington Street Mobil at 1809 W Washington St combines fuel pumps, a drive-through car wash, and a full convenience store under one Mission Hills canopy. Vehicles flagged for check-engine codes or brake noise during fueling stops can schedule diagnostics at Hai's Auto Repair in the adjacent Hillcrest corridor. The wash bay includes a dedicated vacuum station for interior cleaning, and the attached convenience store carries automotive fluids, windshield-washer refills, and packaged food. Owners seeking a deeper clean beyond the automated tunnel can book hand-wash and wax sessions at Jerry's Detailing & Hand Car Wash for full paint decontamination and wheel-face polishing. Fleet operators running multiple vehicles through Mission Hills use the combined wash tunnel and vacuum station to maintain appearance standards between scheduled detail appointments.
