Sinclair Gas Station on Chula Vista's Third Avenue dispenses DINOCARE-branded TOP TIER gasoline, a detergent-enriched fuel certified by automakers including BMW, GM, Honda, and Toyota to reduce intake-valve and combustion-chamber deposits. The station stocks regular, mid-grade, premium unleaded, on-road diesel, and propane-tank exchanges, anchoring the southern Third Avenue fueling corridor alongside Star Best Smog Station's BAR-certified emissions testing just up the avenue. Sinclair's parent brand dates to 1916 and now operates under HF Sinclair Corporation (NYSE: DINO) with more than 1,500 branded stations across 30 states. The on-site air pump and convenience store at the Palomar Street intersection serve the same Third Avenue commuter corridor where Hernandez Tire Pros handles tire rotation and alignment for vehicles that also rely on TOP TIER fuel for long-term engine cleanliness. DINOCARE formulations deliver two to three times the EPA-minimum detergent additive concentration, targeting sub-10-PPM sulfur content under Tier 3 federal gasoline standards.
