Should the Teana use 0w20 or 5w30?
3 Answers
Naturally aspirated models can use 0w20 engine oil, while turbocharged models should use 5w30 engine oil. More relevant information is as follows: 1. Teana Introduction: The Teana is a mid-size sedan under the Nissan brand, with dimensions of 4901mm in length, 1850mm in width, and 1450mm in height, and a wheelbase of 2825mm. This car is equipped with two engines: a 2.0-liter naturally aspirated engine and a 2.0-liter turbocharged engine. 2. Engine Introduction: The 2.0-liter naturally aspirated engine delivers 156 horsepower and a maximum torque of 197 Nm, reaching its peak power at 6000 rpm and maximum torque at 4400 rpm. This engine features direct fuel injection technology and uses an aluminum alloy cylinder head and block. The 2.0-liter turbocharged engine produces 243 horsepower and a maximum torque of 371 Nm, achieving peak power at 5400 rpm and maximum torque at 4400 rpm. 3. Vehicle Configuration: This engine is equipped with hybrid injection technology and also uses an aluminum alloy cylinder head and block. Both engines are paired with a CVT transmission, which enhances gear-shifting smoothness and fuel economy. For the chassis design, the front suspension employs a MacPherson independent suspension, while the rear suspension uses a multi-link independent suspension. The multi-link suspension is a structurally complex independent suspension system.
I've been driving a Teana for seven years and currently use 0W20 oil, which indeed reduces fuel consumption by one or two percentage points compared to the previous 5W30. Nissan officially recommends 0W20 primarily for fuel economy, especially in urban driving conditions where the start-stop system frequently operates. 5W30 provides more stable oil film at high engine speeds, offering better protection during long-distance driving in summer. For older cars with over 100,000 kilometers, switching to 5W30 can be considered, but for new cars, it's advisable to follow the maintenance manual. Dealerships now default to adding 0W20, so there's no need to change the viscosity yourself. I've compared both oils, and 0W20 makes the engine noticeably quieter during cold starts, which is quite important during Beijing winters.
The most accurate reference is the vehicle manual, which clearly recommends 0W20 for Nissan Teana. This low-viscosity oil offers excellent fluidity, ensuring instant lubrication during cold starts to minimize engine dry friction. Most turbocharged models now recommend 0W20 as it's compatible with auto start-stop systems. Of course, 5W30 has its advantages too, especially in high-temperature regions like Hainan, where its thicker oil film provides better protection during sustained high-speed driving. I suggest sticking with 0W20 during the initial maintenance period, then adjusting based on driving habits after three years. Owners who frequently drive mountain roads or prefer aggressive acceleration may switch to 5W30 for better wear cushioning.
