What kind of engine oil should the Vezel use?
2 Answers
The naturally aspirated engine models of the Vezel can use full synthetic oil with a viscosity of 20, while the turbocharged engine models should use full synthetic oil with a viscosity of 30. The functions of engine oil are: 1. To reduce friction and high temperatures; 2. To minimize gas leakage and prevent external pollutants; 3. To prevent contact between water, air, harmful acidic gases, and engine components; 4. To buffer the pressure rise in the engine cylinder ports; 5. To clean dirt generated on the working surfaces of components. The Vezel is a compact SUV with dimensions of 4328mm in length, 1772mm in width, and 1605mm in height, a wheelbase of 2610mm, a fuel tank capacity of 50 liters, and a curb weight of 1227kg.
I've been driving the Vezel for three years and I'm very particular about engine oil. The Honda manual clearly states to use 0W-20 viscosity oil. In the south where winters aren't that cold, 5W-20 is also acceptable. Last month during maintenance, I used Shell Helix Ultra, a fully synthetic oil, and the engine noise noticeably reduced. Using oil with too high viscosity actually increases fuel consumption and harms the engine. The 4S shop mechanic said never to randomly switch to higher viscosity oil. Maintenance intervals depend on driving habits - I frequently drive on highways so I change it every 8,000 km, but if there's more city traffic with frequent stops, it's safer to change at 7,000 km. Always use genuine oil filters - don't skimp on a 20-yuan item.
