Should the Arrizo 5 use 5w30 or 5w40?

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.

As someone who has worked in auto repair shops, I know that choosing the wrong engine oil can easily cause engine burrs. For the Arrizo 5, 5W30 is preferred as it's thinner and suitable for general driving and low-temperature environments. However, 5W40 is thicker and provides more stable oil pressure at high temperatures. Without the manual, use 30 for new cars, while older cars or those frequently driven on highways can consider 40. Checking the oil is simple: open the engine hood and look at the dipstick to ensure it's within the marked range. Also, pay attention to the API certification of the oil—SN grade or above offers better protection, saving you money on future oil changes. Develop good habits by not exceeding the manufacturer's recommended oil change intervals, prioritizing safety and reliability.

In our mild four-season climate, 5W30 is the most cost-effective choice. It offers good fluidity for quick winter starts and resists overheating in summer, perfectly matching the standard engine design of the Arrizo 5. While 5W40 suits extreme heat or high-intensity driving, it's unnecessary for regular family use. With rising fuel prices, thinner oil can save about 0.5 liters per 100km. Always check your manual - manufacturers have tested what works best for your car. Mention it during routine maintenance, and technicians can check if viscosity adjustments are needed.

For those who enjoy driving fast or going on long trips, I recommend 5w40 for the Arrizo 5. It's thicker, maintaining stable oil pressure at high speeds to protect engine components and reduce wear. For normal, gentle driving, 5w30 is sufficient—it's fuel-efficient and smooth. Driving habits are crucial; frequent rapid acceleration can raise oil temperature, and prolonged use of thin oil may lead to cylinder burning. Take care of your car; choosing the right oil can extend its lifespan. Also, ensure the oil level doesn't drop below the min line to avoid potential issues.
