Can Mazda CX4 use 5w30 engine oil?
2 Answers
Mazda CX4 can use 5w30 engine oil, but it is recommended to use 0w20 engine oil. Here is more information about engine oil: 1. Functions of engine oil: Engine oil can lubricate and reduce wear, assist in cooling, seal and prevent leakage, prevent rust and corrosion, and provide shock absorption for the engine. 2. Composition: Engine oil consists of base oil and additives. Base oil is the main component of lubricating oil, determining its basic properties, while additives can compensate for and improve the shortcomings of base oil, giving it certain new properties, making it an important part of lubricating oil.
The Mazda CX-4 I drive is a 2018 model with the Skyactiv engine. According to the owner's manual, it explicitly recommends using 5W30 or thinner 0W20 engine oil to optimize fuel economy and protect the engine. The oil viscosity rating 5W30 indicates lower viscosity in winter and moderate viscosity at high temperatures, making it suitable for most driving conditions, including city commuting and highway driving. In practice, I have consistently used 5W30 synthetic oil, and over three years and 60,000 kilometers, there have been no issues—the engine runs smoothly, and fuel consumption remains around 7.5L/100km. However, it's important to note that performance can vary with climate: 5W30 performs better in hot regions, while 0W20 may allow quicker starts in cold winters. If your CX-4 is an older model or has a turbocharged version, it's best to check the manual for confirmation. Avoid switching to higher-viscosity oils like 10W40, as this can increase wear or fuel consumption. In summary, 5W30 is a viable choice, but always follow the manufacturer's guidelines.
