Nissan's new Teana generally uses the 0W-30 type. Below is an introduction about engine oil: 1. Function: It can lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and cushion shocks for the engine. It is known as the 'blood' of the car. 2. Grade: The engine oil grade includes two parts: classification and viscosity specification. The oil grade usually indicates viscosity and quality. W stands for winter, and the smaller the number before it, the better the oil's low-temperature fluidity, indicating a lower usable ambient temperature and better protection for the engine during cold starts. The number after 'W' (after the hyphen) is an indicator of the oil's high-temperature resistance, with a higher number indicating better protection performance at high temperatures.

I remember when I used to maintain my Teana, I always used 0W-20 or 5W-30 fully synthetic oil, which is clearly recommended in the owner's manual. This viscosity is most suitable for the Teana's engine design, improving fuel efficiency and reducing consumption. After driving for three or four years, I noticed the engine runs particularly smooth after an oil change. However, the choice of oil grade depends on the car's model year and driving conditions. For example, 0W-20 is better for winter as it prevents freezing, while 5W-30 works fine in summer. But avoid using semi-synthetic oil randomly, as it can easily lead to sludge buildup and affect engine lifespan. I make it a habit to check the oil level every six months or after driving 5,000 kilometers, and I also replace the oil filter at the same time. It saves money and extends the car's service life. During maintenance, chatting with the technicians can help you find the right specifications.

From my experience, the Nissan Teana performs best with 0W-20 or 5W-30 fully synthetic engine oil, which is durable and eco-friendly. I chose this viscosity mainly for its fuel efficiency, saving costs per kilometer, and significantly reducing engine noise. However, it's important to note that viscosity selection should consider seasonal changes: use 0W-20 in cold regions to prevent freezing, while 5W-30 suffices in warmer areas. Always consult professional advice during maintenance. Additionally, reputable brands like Shell or Mobil 1 are highly reliable. Stick to an oil change interval of no more than 8,000 km to prolong engine life and reduce carbon emissions, making a small environmental contribution.

When I first bought my Teana, I was reminded to use 0W-20 full synthetic oil, and I've stuck with this specification for every maintenance since. It makes the engine more responsive, reduces fuel consumption, and provides a more worry-free driving experience. Before choosing engine oil, check the manual or call the 4S store—they'll directly recommend the right type. Don't skimp on this small expense; good oil protects the engine and avoids costly overhauls.
