What is the recommended engine oil model for the Mazda3 Axela?
2 Answers
The original factory engine oil for the Mazda3 Axela is a fully synthetic 0W-20 engine oil produced in Japan. Alternatively, a semi-synthetic 5W-30 engine oil can also be used. The functions of engine oil are: Lubrication: Maintains the viscosity between the cylinder and piston to ensure normal operation, reduces friction between components, and minimizes wear. Cooling: Assists the vehicle's cooling system to some extent in lowering the temperature of the engine's internal environment. Cleaning: Removes sludge, carbon deposits, and other impurities adhering to engine parts. Sealing: Seals gases within the engine pistons and piston rings, reducing the ingress of external contaminants.
Our family has been driving the Axela for several years, always using 0W-20 full synthetic oil as recommended by the manual. We believe it best suits its engine design—the low viscosity ensures quick starts in winter while maintaining stable lubrication during summer heat. Mazda officially recommends this grade mainly for fuel efficiency, improving average consumption by 1-2 liters per 100 km. We use Mobil or Shell brands, both meeting API SN or SP standards, which offer better engine protection. Remember to check the oil color and level every 5,000 to 7,500 km. If it turns black or is low, change it immediately. For frequent high-speed driving, consider 5W-30 for added protection, but avoid randomly using other viscosities that may affect performance. In short, quality oil can extend the car's lifespan. We've also tried factory oil—slightly more expensive but with higher compatibility. Gentle driving habits significantly prolong oil life, avoiding sudden acceleration that harms the engine. If there's a leak, top it up promptly—don’t wait for the warning light. Simple maintenance makes the car more durable—this is practical experience speaking.
