Can the Honda Vezel use 5w40 engine oil?

[Julianna]

Honda Vezel models with 1.5L naturally aspirated engines cannot use 5w40 engine oil, while the 1.5L turbocharged models can. When purchasing engine oil, the key factor to consider is the number following the 'w', which represents the high-temperature viscosity—the higher the number, the greater the viscosity. During engine operation, the oil forms a film on the surfaces of various engine components. This film reduces engine operating resistance and minimizes wear on internal parts. If the oil viscosity is too low, it cannot form a stable film, which increases engine wear. Conversely, if the oil viscosity is too high, it increases internal engine resistance, leading to reduced power output and higher fuel consumption. The Honda Vezel is the first SUV under GAC Honda, developed on Honda's all-new vehicle platform.
