What is the engine oil specification for the Geely King Kong manual?
3 Answers
Geely King Kong's dedicated engine oil specification is SJ-10w-30. Oil introduction: 5w represents low-temperature resistance down to -30°C (calculated as 5-35=-30. For example, 0w40 would be 0-35=-35°C). The number 40 represents high-temperature viscosity, determining oil film strength and lubricant thickness. Oil selection method: Based on China's climate conditions, all-season oil can be chosen for most regions, suitable for both winter and summer. All-season oil grades include: 5W/20, 5W/30, 5W/40, 5W/50, etc. The smaller the winter number, the better the low-temperature performance; the larger the summer number, the higher the viscosity and the wider the applicable temperature range.
I've been driving a Geely King Kong for five years, and the manual clearly specifies using 5W-30 engine oil. This all-season oil can start normally even at -20°C and is less prone to deterioration in summer heat. I remember the dealership used Shell Helix 5W-30 during the first service, and I've stuck with this grade for subsequent maintenance. The key is to look for the API certification mark - SN grade or above is recommended for better cleaning and anti-wear performance. Don't cheap out on no-name oils that can cause sludge and engine damage. For my 2,000km monthly commute, changing oil every 8,000km is the safest practice.
After repairing cars for ten years, I've seen too many cases of cylinder scuffing due to wrong engine oil usage. The Geely King Kong's factory manual specifies using semi-synthetic 5W-30 or higher grade—never randomly change the viscosity. Just two days ago, a King Kong owner switched to 10W-40 himself, resulting in engine rattling during cold starts. For older cars exceeding 100,000 km, considering 5W-40 is acceptable, but new vehicles must strictly follow the manual. In winter, remember to check the oil dipstick in advance and top up promptly if it's below the minimum level. Here's a tip: the recommended viscosity parameters are usually engraved inside the oil filler cap.
