What kind of engine oil is best for the new Sylphy?
2 Answers
It is recommended to use 5W-30 semi-synthetic engine oil for the new Sylphy. Below are the related functions of engine oil: 1. Lubrication: There is rapid relative sliding between the piston and cylinder, as well as between the main shaft and bearing bush. To prevent excessive wear of parts, an oil film needs to be established between the two sliding surfaces. A sufficiently thick oil film separates the surfaces of the relatively sliding parts, thereby reducing wear. 2. Auxiliary cooling: Engine oil has a relatively low specific heat value and is located inside the engine, so it does not inherently have a cooling effect. However, during engine operation, the heat energy generated by fuel combustion can be carried back to the oil tank by the engine oil and then dissipated into the air, assisting the radiator in cooling the engine. The actual cooling effect is provided by the water (or antifreeze liquid) outside the engine casing. 3. Cleaning: High-quality engine oil can carry carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank through circulation. The flow of the lubricating oil washes away dirt generated on the working surfaces of the parts. 4. Sealing and leak prevention: Engine oil can form a sealing ring between the piston rings and the piston, reducing gas leakage and preventing external contaminants from entering.
I've been driving the new Sylphy for several years. According to the official manual recommendation, it's advised to use 5W-30 full synthetic engine oil, which provides excellent engine protection, quick cold starts, and fuel efficiency. The Sylphy's engine is quite precise, and synthetic oil helps reduce wear and carbon buildup, extending engine life in the long run. I usually opt for reputable brands like Mobil or Shell, with a barrel costing around 400-500 RMB, offering good value for money. The oil change interval depends on driving habits: every 5,000 km for city driving, and up to 7,500 km for mostly highway driving. Don't skimp by using mineral oil, as it can lead to issues; synthetic oil has more additives, stronger cleaning performance, smoother driving, and reduced noise. Routine maintenance is simple—just get it changed at a 4S shop or reputable service center, and it's even more reassuring to combine it with an air filter check. The overall cost isn't high, making it a great value for maintaining a new car.
