Should the Arrizo 5 use 5w30 or 5w40?
2 Answers
Arrizo 5 recommends using 5w30. This car is equipped with a 1.5-liter naturally aspirated engine across the entire lineup, and this engine can use 30 or 20 viscosity oil. When selecting oil viscosity, it is essential to choose based on the technical characteristics of your car's engine. During normal engine operation, the oil forms a film on the surface of various engine components, which reduces wear between parts and lowers the operating resistance of engine components. The oil viscosity should not be too high or too low. If the viscosity is too low, the oil cannot form a stable film during engine operation, which will increase engine wear. If the viscosity is too high, it will cause increased resistance during engine operation, leading to reduced engine power and higher fuel consumption. The body dimensions of the Arrizo 5 are 4572mm in length, 1825mm in width, and 1482mm in height.
I've been driving the Arrizo 5 for several years, and this issue is quite common. Generally, 5w30 is recommended because this viscosity is moderate, ensuring smoother cold starts, especially in the morning when the engine responds quickly, and fuel consumption is lower. However, it depends on your car's condition and environment. If you frequently drive in high-temperature areas or your car has high mileage, say over 100,000 km, with increased engine wear, switching to 5w40 can provide extra protection by preventing the oil film from being too thin. The car's manual is the authoritative reference—check it, as it may specify the recommended oil, since requirements vary for different model years of the Arrizo 5. Don’t forget to change the oil regularly, every 5,000-10,000 km, to keep the engine durable and avoid minor issues turning into major ones.
