Nissan Teana 2.0 maintenance can use semi-synthetic engine oil. It is best to use 5W-30 engine oil. The following is an introduction to engine oil: 1. Function: Engine oil can lubricate and reduce wear, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine. 2. Meaning: The classification and numbering of engine oil indicate its viscosity specification. For example, in "15W-40, 5W-40," the letters and numbers represent the following meanings: (1). "W" stands for Winter, and the smaller the number before it, the better the low-temperature fluidity of the engine oil, indicating a lower usable environmental temperature and better protection for the engine during cold starts. (2). The number after W represents the kinematic viscosity of the engine oil at 100℃, with higher values indicating higher viscosity.

As a Teana 2.0 owner who has driven it for several years, I find that using 5W-30 full synthetic oil is the most suitable for maintenance, as it protects the engine in all weather conditions. During daily driving, I've noticed that Nissan's original factory-recommended viscosity is exactly this, ensuring smooth performance from cold starts to high speeds. Avoid using cheap mineral oils, as they can make the engine noisy or increase fuel consumption. Opt for reputable brands like Shell or Mobil, and change the oil every 5,000 kilometers, while also checking the air filter. This way, your car can run longer and smoother. I've personally tried different oils, and although full synthetic is more expensive, it actually saves money on fuel and repairs in the long run, making it a worthwhile investment. Also, make sure to regularly check the maintenance manual to ensure the viscosity matches your car model, and don’t rely on guesswork.

As a long-time car enthusiast, when it comes to the engine oil for the Teana 2.0, my top recommendation is 0W-20 full synthetic oil. The thinner viscosity allows for more efficient engine operation. This engine is designed with fuel efficiency in mind, and 0W-20 ensures quick starts in cold weather and stable lubrication in hot conditions, preventing wear and tear. I suggest opting for brands with API SP certification, such as Castrol or the manufacturer's original oil, and avoid mixing different viscosities. After an oil change, you'll notice smoother performance over a few thousand kilometers. Remember to regularly replace the oil filter to maintain cleanliness, which overall extends the vehicle's lifespan and results in quieter operation with fewer unusual noises.

Considering daily expenses, for the Teana 2.0, I opt for an economical 5W-30 full synthetic oil—moderately priced but long-lasting. Purchasing reliable brands like Great Wall at supermarkets ensures the viscosity suits most road conditions. Maintain an oil change interval within 6 months or 5,000 km to avoid frequent changes and save money. If you frequently drive long distances, adding high-quality additives can protect the engine and reduce maintenance frequency. While saving costs, don’t overlook basic inspections.
