The Teana uses 0W20 or 5W30 engine oil, which serves functions such as lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption and buffering. Taking the 2021 Teana as an example, its body dimensions are: length 4901mm, width 1850mm, height 1450mm, with a wheelbase of 2825mm and a fuel tank capacity of 61.3 liters. The 2021 Teana is equipped with a 2.0L naturally aspirated engine, delivering a maximum power of 115kW and a maximum torque of 197Nm. It features a MacPherson strut front suspension and a trapezoidal control arm multi-link independent rear suspension.

My old Teana has been running for over eight years, and I've always used 5W-30 full synthetic oil for maintenance. Both the car manual and dealer recommendations specify this viscosity as the most suitable. Nissan engines require good fluidity during cold starts, and the 5W part ensures it won't freeze even in sub-zero temperatures. The 30 indicates sufficient oil film strength at high temperatures, providing top-notch anti-wear performance. I live in an area with distinct seasons—hot summers and cold winters—and this oil has never caused any issues. The engine runs quieter, and fuel consumption remains stable at around 10L/100km. When buying oil, opt for reputable brands like Shell or Mobil, preferably with API SP certification. Don’t skimp and use mineral oil, or you’ll end up with excessive carbon buildup and doubled repair costs in the long run. Check the oil level every 5,000 to 7,000 km, and follow the manual’s oil change intervals. The Teana is sturdy, but using the wrong oil drastically reduces engine lifespan.

I've seen plenty about oil changes. The Nissan Altima generally recommends 5W-30 full synthetic oil, whose viscosity perfectly matches the engine design. The manual advises against high-viscosity grades like 10W-40, as increased resistance affects acceleration. For owners who frequently drive on highways or carry loads, using high-quality synthetic oil reduces wear and ensures quiet operation. Prioritize API SP-certified oil for guaranteed cleanliness. The recommended change interval is every 8,000 km or six months, especially in cold northern regions. Hybrid models may differ slightly—checking the manual is always correct. Using cheap oil carries risks like black smoke or strange noises; don't penny-pinch at the cost of bigger issues. Daily maintenance is simple: check the dipstick before starting, and top up drop by drop if low. Long-term neglect of oil quality will lead to shocking repair bills.

Hey, a friend who drives a Teana told me he uses 5W-30 synthetic oil and feels the engine runs smoother with quicker acceleration. I tried it too, and it doesn't overheat in traffic jams. For brands, Total or Castrol offer good value for money. The manual recommends this viscosity for its versatility—no stuttering when starting in sub-zero winters and stable oil temperature during summer road trips. Remember to change it regularly, don't slack off every 5,000 km. Fuel-saving tip: Good oil actually saves money, like cutting a liter per 100 km. Keep maintenance simple, don't overcomplicate it.
