The Dongfeng Nissan Sylphy uses SL-grade 10W30 mineral engine oil. The functions of engine oil include: lubrication, auxiliary cooling, cleaning, sealing and leak prevention, rust and corrosion protection, shock absorption, and anti-wear. Taking the 2021 Dongfeng Nissan Sylphy as an example, it is a compact car with body dimensions of: length 4631mm, width 1760mm, height 1503mm, a wheelbase of 2700mm, and a minimum ground clearance of 166mm. The 2021 Dongfeng Nissan Sylphy is equipped with a 1.6L inline 4-cylinder naturally aspirated engine, delivering a maximum horsepower of 122PS, a maximum torque of 155Nm, and a maximum power of 90kW. It is paired with a 5-speed manual transmission.

I've been researching car maintenance, and for the Nissan Sylphy, it's recommended to use fully synthetic engine oil with a viscosity of 0W-20 or 5W-30, especially those with API certification and ILSAC standards like GF-6. This low-viscosity oil ensures smoother engine starts in cold weather, reduces internal friction, and improves fuel efficiency. After using it in my Sylphy for two years, I've noticed a roughly 5% reduction in fuel consumption and significantly quieter engine operation. It's crucial not to use the wrong oil, as it could accelerate wear or lead to overheating issues. The manual suggests changing the oil every 5,000 kilometers or six months, and it's a good habit to regularly check the oil level for safety. Opting for reputable brands like Castrol or Shell ensures reliable quality and peace of mind. With proper engine protection during long-distance driving, the ride becomes more stable.

My Nissan Sylphy has been running for five years, always using 0W-20 synthetic oil, and the results have been excellent. Just make sure the oil bottle is labeled with ILSAC GF-6 certification, and don't cheap out on no-name brands. I've noticed that with lower viscosity oil, the car starts faster in winter and has more responsive acceleration. On average, fuel consumption stays around 7 liters, which is more reliable than randomly using other oils. I recommend buying good oil yourself and having it changed at a repair shop to save some money. Oil changes should be timely, as accumulated dirt can affect performance. The engine is the heart of the car—proper maintenance ensures it runs longer. The money saved on long-term repairs far outweighs the cost of oil.

Choosing engine oil depends on the requirements of the Nissan Sylphy. I often recommend 0W-20 synthetic oil as it adapts to most climates. The right viscosity reduces engine wear, ensures smooth starts, and saves fuel. Don't overlook the certification marks on the oil bottle—ILSAC GF-6 is the most reliable. Don't exceed the mileage interval specified in the manual. Good oil makes the car quieter and improves the driving experience. Maintenance is simple—just follow regular servicing.
