What kind of engine oil should be used for Nissan Teana 2.0 maintenance?

[LaJustin]

Nissan Teana 2.0 maintenance uses 5W-30 engine oil, and it is generally recommended to follow the manufacturer's recommended specifications. The following are relevant information: 1. Engine oil can lubricate, clean, cool, seal, reduce friction, prevent rust, and prevent corrosion for the engine. 2. The engine is the heart of a car. There are many metal surfaces in the engine that rub against each other during movement. These components operate at high speeds and in harsh environments, with working temperatures reaching 400°C to 600°C. Under such severe conditions, only qualified lubricating oil can reduce the wear of engine parts and extend their service life. 3. The grade after the oil classification indicates its viscosity specification. For example, in "15W-40, 5W-40," "W" stands for Winter, and the smaller the number before it, the better the low-temperature fluidity of the oil, indicating a lower usable environmental temperature and better protection for the engine during cold starts. For example, 5W represents resistance to external low temperatures of -30°C, while 20W is resistant to -15°C. The number after W represents the kinematic viscosity of the oil at 100°C, and the higher the number, the higher the viscosity.
