What Type of Engine Oil Should Be Used for China VI Gasoline Vehicles?
3 Answers
China VI vehicles should use 5W30 semi-synthetic engine oil. The choice of engine oil should be based on the engine's requirements. It is unnecessary to use overly advanced oil in engines with lower requirements, nor should lower-grade oil be used in engines with higher requirements. Always select the oil type recommended in the user manual. Mineral Oil: Mineral oil is a commonly used lubricant in the market. It is derived from the useful substances separated during petroleum refining, with the remaining base oil further processed and extracted. Semi-Synthetic Oil: Semi-synthetic oil is made from semi-synthetic base oil, which is a product of mineral oil purified through hydrocracking technology. It consists of a mixture of mineral oil and full synthetic oil in a 4:6 ratio. Full Synthetic Oil: This is the highest-grade oil, derived from ethylene and propylene dispersed from natural gas or crude oil's gas components. It undergoes complex chemical reactions such as polymerization and catalysis to form a lubricating fluid composed of large molecules.
For China VI gasoline vehicles, choosing the right engine oil is quite particular—low-ash formulations like SP or SN grade are essential. This is because the China VI emission standards are stringent, and high-ash oil can clog the DPF after-treatment system, causing vehicle issues. Typically, viscosities like 0W-20 or 5W-30 are recommended, but always refer to your car’s manual for specifics. I once neglected this and ended up with higher fuel consumption and engine vibration. Later, at the dealership, they recommended a certain brand’s SP-grade 0W-20 oil—after the change, power improved noticeably, and emissions were cleaner. Remember to check oil levels regularly and replace it every 5,000 to 8,000 km to avoid long-term engine damage from low-quality oil. When selecting oil, prioritize API-certified low-ash versions—better for the environment and fuel efficiency. In short, don’t buy blindly; consult professional mechanics.
For China VI gasoline vehicles, it's crucial to choose the right engine oil model. After driving a China VI car, I've done some research. The best options are SP or SN plus grade oils with ash content controlled below 0.8%. In terms of viscosity, 0W-20 is most common, but 5W-30 may also be suitable. The reason is simple: China VI emission systems are sophisticated, and high ash content can damage the particulate filter, triggering warning lights or power loss. During maintenance, I've found that timely oil changes extend engine life. Recommended brands include Shell or Mobil's low-ash series. Always cross-check with the owner's manual as requirements may vary by model. Don't compromise with non-standard oils to save money, as repair costs could be higher. Personally, I change oil every six months for smooth and eco-friendly performance. Remember, engine oil is the lifeblood of your car - choosing the right model ensures safety.
