Does Using China 6 Engine Oil in a China 5 Vehicle Have Any Impact?
2 Answers
Using China 6 engine oil in a China 5 vehicle has no impact. Relevant information about engine oil is as follows: Function: Engine oil, also known as engine lubricant, with a density of approximately 0.91×10³ (kg/m³), serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption and cushioning for the engine. It is often referred to as the 'blood' of a car. Composition: Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties, while additives compensate for and improve the shortcomings of the base oil's performance, imparting certain new characteristics, making them an important part of lubricating oil.
I've been driving a China 5 standard car for several years, and recently used China 6 standard oil during an oil change at the 4S店. Honestly, there were no issues at all. To be frank, the national standards for engine oil are mainly related to emissions—for example, China 6 oil is designed to reduce exhaust pollution, but it works perfectly fine in China 5 cars. The key is to match the viscosity. Just check your car’s manual for the recommended viscosity and buy China 6 oil accordingly—no problem at all. Personally, I feel the engine runs smoother after the change, possibly because the new oil has higher cleanliness and removes old carbon deposits. Plus, China 6 oil is more widely available in the market now, and sometimes it’s even cheaper on discount. In daily driving, there’s no change in fuel consumption, and it’s completely safe. Remember, when engine oil standards are upgraded, they’re usually backward compatible. Older cars might even benefit from better maintenance, saving both money and hassle.
