Can Teana use 5w40 engine oil?
1 Answers
Teana can use 5w40 engine oil, but it depends on the situation. Different vehicle conditions are as follows: If you are a new Teana owner who has just purchased the car, it is not recommended to use 5w40 engine oil during the first maintenance. Since 5w40 has relatively higher viscosity, poorer fluidity, and greater resistance, it increases the engine's operating resistance, thereby increasing the car's fuel consumption. Additionally, new cars have a break-in period and are not suitable for using high-viscosity engine oil. It is recommended to use the fully synthetic 5w30 engine oil specified in the maintenance manual. However, if the Teana is already around 10 years old, then using 5w40 engine oil is recommended. As cars age, engine wear becomes more severe compared to new cars, and the higher viscosity of 5w40 oil compared to 5w30 helps protect the engine's components. Engine oil recommendations: If you frequently drive on highways, using 5w40 engine oil is recommended. When driving at high speeds, the engine operates more intensely, leading to significantly increased heat generation and wear. In such cases, the higher viscosity and better high-temperature resistance of 5w40 oil are beneficial. Conversely, if you often drive in congested urban areas, using lower viscosity 5w30 oil is recommended. Using 5w40 oil in such conditions can lead to excessive engine carbon buildup and increased fuel consumption.
