Is it necessary to use fully synthetic engine oil for Haval H2?

It is necessary to use fully synthetic engine oil for Haval H2 because the engine is a turbocharged engine. Original engine oil used for Haval H2: The original engine oil for Great Wall Haval H2 is SL grade 10W-40 fully synthetic oil. Any fully synthetic oil that meets this specification can be used. Selection of engine oil: In recent years, for environmental protection and fuel economy considerations, low-viscosity oils such as 5W-20 are recommended. Just follow the manufacturer's recommendations. Of course, if the manufacturer does not specify, you can choose engine oil based on the vehicle usage environment. Generally speaking, commonly available oils like 0W-40, 10W-40 and 5W-40 have strong applicability and can suit the climate in most parts of China and the use of most vehicles.
As an owner of a Haval H2 for nearly three years, I don't see the necessity of always using full synthetic oil. The vehicle's manual recommends SAE 5W-30 or 10W-30 oil. While full synthetic does offer better lubrication and longer lifespan, it comes at a significantly higher price. For city commuting, semi-synthetic or mineral oil is sufficient—it's more cost-effective and still protects the engine. I've tried full synthetic and stretched the oil change interval to 8,000 km, whereas with semi-synthetic, I had to change it every 5,000 km, saving hundreds of yuan. If you frequently drive on highways or have high-load demands, like towing, full synthetic might be more stable to prevent wear. Overall, it depends on your budget and driving habits—no need to overspend unnecessarily. For regular driving conditions, choosing a certified quality oil is adequate.
