What is the most suitable engine oil for Mazda CX-4?
2 Answers
Mazda requires the use of 0W-20 full synthetic engine oil for maintenance of its models. The following is an introduction to engine oil: Classification of engine oil: Engine oils on the market can be simply divided into mineral oil and synthetic oil based on their base oil (vegetable oil is not considered due to its scarcity). Synthetic oils are further divided into full synthetic and semi-synthetic. Precautions for changing engine oil: For new cars under normal driving conditions, if synthetic oil is used, the oil can generally be changed every 10,000 kilometers, and sometimes even extended to 20,000 kilometers. Under "severe driving" conditions, engine wear is greater, and the requirements for engine oil are higher. Therefore, it is recommended to shorten the oil change interval to effectively protect the engine.
I've been driving my CX-4 for almost four years now, always sticking to 0W-20 viscosity full synthetic oil, especially brands like Idemitsu or Mobil that meet Mazda's certification. The Skyactiv engine has an exceptionally high compression ratio, so oil with good fluidity during cold starts in winter is crucial to reduce wear. Initially, I tried 5W-30, but fuel consumption increased by almost 1 liter, and the engine noise became louder. The manual specifies GF-5 or SN grade standards, which shouldn't be taken lightly—using the wrong oil and damaging the engine is no small matter. I change the oil every 8,000 kilometers, or up to 10,000 kilometers if I drive more on highways. During maintenance, it's always a good idea to have the mechanic check the oil level.
