Supreme Gasoline on Chula Vista's Broadway corridor combines a fuel station, beer store, convenience market, and self-service car wash under one roof at 196 Broadway near the H Street commercial node. The integrated wash bay complements the exterior-cleaning options along the same Broadway stretch served by Pearl Car Wash farther south, though Supreme's version pairs directly with a fill-up for single-stop vehicle care. Pumps carry regular, mid-grade, premium unleaded, and on-road diesel alongside propane-tank exchanges, and the attached market accepts SNAP/EBT for grocery and household purchases. The Broadway automotive ecosystem surrounding the station includes pre-owned vehicle sales at Broadway Auto Group, giving residents a concentrated vehicle-services corridor between H Street and Main Street. Supreme's dual-island pump configuration handles both gasoline and diesel dispensing through multi-product dispensers equipped with vapor-recovery Stage II nozzles required under California Air Resources Board regulations.
