What type of engine oil is suitable for the Great Wall M4?
2 Answers
The original engine oil specification for the Great Wall M4 is Total. For the M4 engine, a fully synthetic oil with an SN grade and viscosity of 5W-30 is most suitable. It is recommended to use fully synthetic oil because it provides excellent lubrication, which can extend the engine's lifespan. Brands like Mobil, Shell, and Castrol are all good options. Below is some relevant information about engine oil: 1. Functions of engine oil: Engine oil lubricates and reduces friction in the engine, assists in cooling, seals against leaks, prevents rust and corrosion, and acts as a shock absorber. It is often referred to as the 'blood' of a car. Choosing the right oil and changing it regularly helps maintain the engine in good condition and prolongs its service life. 2. Choosing engine oil: When selecting engine oil, the most expensive option isn't necessarily the best. Instead, the choice should be based on the characteristics of the car's engine and the driver's habits. Engine oil can also be categorized based on winter and summer use. For winter, the primary consideration is the low-temperature viscosity grade, while in summer, due to higher temperatures, an oil with a superior low-temperature viscosity grade is not necessary.
As a former owner of a Great Wall M4, I think choosing the right engine oil is quite important—don’t just use any oil. Generally, 5W-30 synthetic oil is recommended, as it performs well during cold starts in winter and prevents engine overheating in summer. I usually use brands like Shell or Mobil, changing the oil roughly every 5,000 kilometers. Also, make sure to check for the API SN standard—it offers more reliable engine protection. Using a higher-viscosity oil like 5W-40 is also an option, but it may increase fuel consumption. In short, don’t skimp on cheap, low-quality oil. Regular maintenance can prevent major repairs, and the car can run smoothly for a decade. If the dipstick shows dark oil, change it immediately.
