What kind of engine oil is suitable for the Teana?
2 Answers
In addition to using the original factory oil, the Teana can also use fully synthetic 0w40 oil, which can be changed once a year or every 10,000 kilometers. It is recommended to perform maintenance in advance. Engine oil, motor oil, or engine lubricant is a type of substance enhanced with additives in base oil, mainly containing anti-wear additives, detergents, dispersants, and multi-grade oil viscosity index improvers. The main functions of engine oil are to reduce friction and wear on moving parts and to remove sludge and varnish from the engine. The Teana is a flagship mid-to-high-end luxury sedan under NISSAN, with body dimensions of 4901mm in length, 1850mm in width, 1447mm in height, and a wheelbase of 2825mm.
I've been driving the Teana for several years and found that choosing engine oil is quite particular. Generally, 5W-30 viscosity is recommended because it adapts well to various seasons—it doesn’t harden in summer heat and ensures smoother cold starts in winter. Full synthetic oil is the best choice, offering long-lasting lubrication, better fuel efficiency, and superior engine protection against excessive wear. I used to use mineral oil, but after switching to full synthetic, the engine became noticeably quieter, even on long trips without strange noises. However, it depends on the car’s age—older Teana models might be fine with 5W-40, but don’t randomly change viscosities. Change the oil every 5,000 to 8,000 kilometers and regularly check the oil level to avoid leaks and damage. In short, don’t skimp on cheap, off-brand oils—stick with reputable brands like Shell or Castrol for safety and peace of mind.
