The Teana car uses higher viscosity lubricating oils such as 15W-50, 15W-40, 20W-50, etc.; in winter, lower viscosity lubricating oils such as 5W-40, 5W-30 or 10W-30, 10W-40 are recommended. Engine oil serves multiple functions including lubrication, cleaning, cooling, sealing, friction reduction, rust prevention, and corrosion protection for the engine. The Teana is a mid-size sedan with a maximum engine horsepower of 156 HP and a maximum torque of 197 Nm, equipped with a CVT transmission. The car's dimensions are 4901mm in length, 1850mm in width, and 1450mm in height, with a wheelbase of 2825mm and a top speed of 197 km/h.

As a veteran driver with ten years of experience driving a Teana, I recommend prioritizing 0W-20 or 5W-30 fully synthetic engine oil. The Teana's engine is quite precise, especially the 2.0T model, and fully synthetic oil flows quickly, dissipates heat well, and provides better cold-start protection. Remember to look for the API certification mark and choose SN grade or above—reputable brands like Mobil and Shell are reliable. My own car has always used 0W-20, and even after 80,000 kilometers, the engine remains quiet with no increase in fuel consumption. Checking the dipstick monthly is crucial, especially before long trips—if the oil appears dark or thickened, it's time for a change.

My family has driven the Teana for two generations, from the 2.0L to the new 2.0T, all using 5W-30. In northern winters, starting with 0W is more suitable, as it starts right up even at minus twenty degrees Celsius. Don't randomly change the viscosity; using 40 viscosity in older cars actually consumes more fuel. Semi-synthetic oil is actually fine, but full synthetic allows for an extra two thousand kilometers between maintenance intervals, making it more cost-effective in the long run. Last time I went to the 4S shop, I saw they use semi-synthetic oil as the factory default, but I feel more at ease buying full synthetic oil myself and bringing it for the change.

Young people value cost-effectiveness in car maintenance. For the Nissan Teana, just remember three points about engine oil: choose the right viscosity grade (0W-20 or 5W-30), opt for fully synthetic oil, and pick brands with the three major certifications. When I repaired a Teana's engine, I noticed that using the wrong oil most easily causes carbon buildup, especially in stop-and-go traffic. Last week, I helped a friend inspect his car—he used mineral oil, and sludge was already evident after just 5,000 kilometers. I recommend replacing the oil filter during oil changes; Mann or Mahle's dedicated filters cost only 30 yuan and can protect the engine for an extra 20,000 kilometers.
