What type of engine oil does the Nissan Teana use?
2 Answers
Nissan Teana typically uses 0W-30 full synthetic engine oil. Engine oils are categorized into three types, with differences as follows: 1. Mineral oil: A commonly used lubricant in the market. Essentially, it utilizes the inferior components of crude oil. Mineral oil is inexpensive, but its service life and lubrication performance are inferior to synthetic oils, and it also causes significant environmental pollution. Additionally, mineral oil cannot completely remove impurities during the refining process, resulting in a higher pour point, making it unsuitable for use in extreme low-temperature conditions. 2. Semi-synthetic oil: A product purified from mineral oil through hydrocracking technology. It is a mixture of mineral oil and full synthetic oil in a 4:6 ratio. The purity of semi-synthetic oil is very close to that of full synthetic oil, but its cost is slightly higher than mineral oil, making it an ideal transitional product from mineral oil to synthetic oil. 3. Full synthetic oil: Full synthetic oil is a high-grade product among engine oils. It is derived from ethylene and propylene dispersed from natural gas or gas in crude oil, which are then subjected to complex chemical reactions such as polymerization and catalysis to form a lubricating fluid composed of large molecules. In essence, it uses the superior components of crude oil, undergoes chemical reactions, and achieves the desired molecular structure under human control. Full synthetic oil molecules are neatly arranged, with strong resistance to external variables, excellent thermal stability, oxidation resistance, and viscosity change resistance compared to mineral and semi-synthetic oils, but it is also the most expensive.
I've been driving a Nissan Teana for three years and always use synthetic oil. I find that 0W-20 or 5W-30 viscosity works best for it. When I first bought the car and took it to the dealership for maintenance, the technician said the engine is well-designed, and the manufacturer recommends 0W-20 for faster lubrication during cold winter starts, while 5W-30 is more suitable for areas with significant daily temperature variations. I personally prefer using 5W-30 synthetic oil because it protects the engine from excessive wear and saves a bit on fuel costs—just a few extra dollars per liter. The oil change interval is about every 7,500 kilometers; don’t exceed it too much to avoid sludge buildup affecting performance. Once, I tried cheaper oil, and the car made a buzzing noise during acceleration. After switching back to premium brands like Mobil 1 or Nissan’s synthetic oil, the noise reduced significantly. I recommend all owners check the manual’s specifications section for detailed guidelines and avoid experimenting with random choices.
