"Your new car's warranty just made the oil choice for you. Carquest expert explains why modern engines REQUIRE synthetic: tighter tolerances, turbochargers, direct injection, extended intervals. That 0W-20 spec isn't a suggestion - it's survival. 🔧 Synthetic flows instantly, handles extreme heat, protects microscopic clearances. Costs more? One warranty-voiding failure costs more than years of synthetic changes. Cutting corners on oil in a $40K car to save $20 isn't smart - it's expensive. What's the costliest oil-related failure you've seen?
