Can the Honda Vezel use 5w40 engine oil?
2 Answers
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.
I've been driving a Honda Vezel for several years, and friends often ask me about engine oil. Regarding using 5W-40 oil, I don't think it's the best choice. The Honda official manual usually recommends 5W-20 or 0W-20, as this viscosity better matches the engine design and improves fuel efficiency. Using 5W-40, while it offers strong protection in high-temperature environments, increases internal engine friction, leading to higher fuel consumption, and the engine may not run as smoothly during cold starts in winter. My Vezel has always used the manufacturer-recommended oil, and it's run over 50,000 kilometers without any major issues. If the vehicle has high mileage or special modifications, it might be worth consulting a professional, but beginners should stick to the manual to avoid wasting fuel and damaging the car. Regular oil changes are more important than choosing viscosity, ensuring safe driving.
