What Type of Engine Oil Should a Teana Use?
3 Answers
Teana generally uses 5W-30 engine oil. In extremely cold or hot environments, 0W-40 engine oil is recommended. Below is a detailed introduction to engine oil: 1. Classification of Engine Oil: By viscosity: 10W-40 is its SAE standard viscosity value, which indicates that the oil is multi-grade. The 'W' stands for WINTER, and the number before 'W' represents the oil's flow performance at low temperatures. A smaller number indicates better cold-start performance. The number after 'W' represents the oil's stability at high temperatures (i.e., its tendency to thin out). A larger number indicates better high-temperature stability. 2. Oil Selection Method: Choose engine oil that is clear in appearance, low in sulfur content (less than 1.0%), low in residual carbon content (less than 1.0% by weight), low in water and sediment (less than 0.1% by volume), and low in ash content (less than 0.03% by weight).
For the Nissan Teana, the key to choosing engine oil lies in the owner's manual recommendations. Mine states that 5W-30 viscosity is the most commonly used, and synthetic oil type is sufficient to protect the engine with less wear. For newer models, such as those post-2018, the manual may recommend 0W-20 synthetic oil for better fluidity and quicker winter starts. For daily city or highway driving, full synthetic oil offers better high-temperature resistance and fuel efficiency. I change it every 5,000-7,500 kilometers—don't delay too long. Also, pay attention to the oil grade, such as API SP, to ensure environmental compliance and performance. If changing the oil yourself, opt for reputable brands like Mobil or Castrol for easy availability—don’t skimp on quality with cheap alternatives, as they can increase engine noise and degrade driving experience. Regularly check the dipstick and top up if the oil level is low to keep the car running smoothly.
When selecting engine oil for the Nissan Teana, I usually check the manual first. It generally recommends 5W-30 semi-synthetic oil, which is practical enough. Driving conditions can make a difference: in hot summer regions, oil viscosity matters—full synthetic offers more stable engine protection. For cold winters, thinner 0W-20 oil ensures easier starts and less wear. For older models, conventional oil works fine, but change it every 6,000 km or so to avoid clogging the oil passages. API SN or higher-grade oils are more reliable, especially when I do a lot of highway driving—oil performance directly affects acceleration smoothness. Also, don’t overlook replacing the oil filter simultaneously. From a cost perspective, semi-synthetic oil is more economical, balancing savings and safety.
