Which type of engine oil is suitable for Geely King Kong?

[Carmen]

Geely King Kong is suitable for 5W-40 semi-synthetic engine oil. The engine oil must be used correctly. It is essential to use engine oil with an appropriate quality grade, as this is key to ensuring the normal operation of the engine. Engine oil replacement cycle: The replacement cycle for semi-synthetic engine oil is approximately 7,500 kilometers, or about half a year. Ordinary engine oil generally needs to be replaced every three months, but this is not absolute, as it also depends on the grade of the oil. Higher-grade oils have a longer usage cycle. Introduction to semi-synthetic oil: Semi-synthetic oil is one type of automotive engine oil. Engine oils are categorized into fully synthetic oil, semi-synthetic oil, and mineral oil. Semi-synthetic oil is made from semi-synthetic base oil, which is a mixture of mineral oil and fully synthetic oil in a 4:6 ratio. It is slightly more expensive than mineral oil and serves as an ideal transitional product from mineral oil to synthetic oil.

I've repaired quite a few Geely King Kong cars. The manufacturer recommends using 5W-30 or 10W-40 viscosity oil. These domestic car engines aren't picky - mineral oil or semi-synthetic will work fine. In winter, it's advisable to choose 5W-grade oil for better low-temperature fluidity. Don't cheap out on no-name oil brands - Great Wall, Kunlun, or Shell's HX5 series offer good value for money, costing around a hundred yuan. I've seen cases where wrong 20-viscosity oil was used, causing engine rattling during cold starts - older cars especially need proper viscosity matching. Change oil regularly every 5,000 km. If you frequently drive on highways, upgrading to semi-synthetic can significantly reduce engine noise.

I've been driving a Geely King Kong for five years and always use 10W-40 mineral oil, which works particularly well in summer. For oil brands, domestic Kunlun is sufficient and saves half the cost compared to imported brands. A maintenance service only costs around 200 yuan. Remember to check the API rating—SL grade or above is suitable. Older cars actually benefit more from higher viscosity oil. Last time I forgot to change the oil and drove 8,000 kilometers, the engine noticeably lost power. For southern car owners, 10W-40 works year-round, but in northern winters, switching to 5W-30 is more reliable for smoother cold starts below zero.

Choosing engine oil comes down to three key points: check the manual for the recommended 5W-30 viscosity, opt for base models from major brands, and change it promptly based on mileage. For the Geely King Kong, semi-synthetic oil offers the best balance—better protection than mineral oil yet more affordable than full synthetic. My seven-year-old King Kong has been running smoothly on Shell's yellow bottle. Don’t fall for racing-grade oils; SN-grade is sufficient for regular driving. Be mindful of the oil quantity—around 3.5 liters—avoid overfilling to prevent increased fuel consumption.
