What Oil Should Be Used for the First Maintenance of the Haval Third Generation?
2 Answers
For the first maintenance of the Haval third generation, the original factory oil can be used, and the oil model is 5W-30. Vehicle Series Factors: In general vehicle series, the engine is relatively precise with smaller gaps between components, making 5W-30 oil the most suitable. German cars typically use turbocharging technology, resulting in larger gaps, so 5W-40 oil is relatively better. Japanese and Korean cars tend to use oils with 20 or 30 viscosity, such as SAE 0W-20, 0W-30, 5W-20, 5W-30; American cars can use 30 viscosity oil, such as SAE 5W-30, while European cars use 40 viscosity oil, such as 0W-40, 5W-40. Seasonal Factors: Oil selection also varies with the season. Generally, within the reasonable range specified in the vehicle manual, winter recommends oil with better fluidity, such as 5W-30, while summer recommends oil with higher viscosity, such as 5W-40.
Last week, I accompanied my friend to get the first maintenance for his newly purchased Haval 3rd Generation. The 4S shop used the original 5W-30 synthetic engine oil. This viscosity is just right for the new car's engine, providing good cold start protection—it starts even in northern winters at temperatures below minus ten degrees Celsius. Remember to ask the mechanic to show you the oil level by pulling out the dipstick; overfilling can actually increase fuel consumption. The first maintenance is free, but don’t be fooled into adding any engine cleaner—it’s a total waste of money. Also, the original oil container has the Great Wall Motors logo. If they bring you some no-name oil, make sure to ask about it on the spot. After the maintenance, the engine sounded much quieter, and the fuel consumption dropped by a few tenths.
