What kind of engine oil is best for Haval F5?
2 Answers
When the minimum local temperature is around -30°C, it is recommended to use engine oil with a specification of 5W-30. If the minimum temperature in your area is below -30°C, then use engine oil with a specification of 0W-30. Here is a related introduction to engine oil: 1. The engine oil grade indicates the viscosity specification. The "W" stands for Winter, and the smaller the number before it, the better the low-temperature fluidity. The number after the "W" indicates high-temperature protection performance, with a larger number indicating better high-temperature protection. 2. In addition to viscosity specifications, automotive engine oils are also categorized into full synthetic, semi-synthetic, and mineral oils. (1) Mineral oil: This is based on petroleum-refined mineral oil with added additives. Its advantage lies in its affordable price, but its lubrication and protection for the engine are not as high as the other two types. (2) Semi-synthetic oil: This is a middle ground between mineral oil and full synthetic oil. It provides good lubrication and cleaning effects for the engine, with a moderate price and high cost performance. (3) Full synthetic oil: Full synthetic oil offers better lubrication, cleaning, lower friction resistance, and is less prone to oxidation. Its lifespan is 1.5 times that of regular engine oil, but it is also naturally more expensive. Currently, it is highly favored by many car owners.
I've been driving the Haval F5 for a while now. Initially, the 4S dealership recommended mineral oil, but the engine was noisy and fuel consumption was high. Later, I switched to 5W-30 full synthetic oil, and the difference was huge: the power delivery became much smoother, acceleration improved, noise levels dropped significantly, and fuel efficiency even increased slightly. I mainly use it for city commuting, changing the oil every 8,000 kilometers. But if I do more high-speed driving, it's better to check it at 7,000 kilometers. Last winter in Northeast China at minus twenty degrees Celsius, the car started right up without any issues. I've tried both Great Wall's original oil and Castrol, and both performed well. Don't skimp on quality—using the right oil extends engine life and makes maintenance much easier in the long run.
