What is the correct engine oil for Mazda 3?

The correct engine oil for a Mazda 3 typically depends on the model year and engine type, but most recent models recommend using 0W-20 full synthetic oil. Always check the owner’s manual for your specific vehicle for the manufacturer’s recommendations, as it will provide the best guidance for oil viscosity and specifications. Additionally, ensure that the oil meets the API (American Petroleum Institute) standards required for your engine.
