Whether or not you have to use 0W20 oil depends on your vehicle's manufacturer's recommendation. Modern engines are specifically designed for certain types of oil to ensure optimal performance, fuel efficiency, and compliance with emissions standards. If your vehicle's manual specifies 0W20, it's because that oil has the right viscosity and properties for your engine at various temperatures. Using a different oil can lead to decreased performance, higher fuel consumption, and possibly even engine damage. Always consult your owner’s manual or a professional before making a switch.
