0W-20 engine oil is mostly suitable for Japanese and Korean vehicle models. In addition, some German vehicle brands like Mercedes-Benz, BMW, Volkswagen, and Audi also recommend it. This is because the engines they use are designed with lightweight, high density, high precision, and low clearance, and low viscosity oil can fully meet the requirements of such engines.
Generally, as a fully synthetic oil, 0W-20 engine oil has a shelf life of around 3 years, and the recommended oil change interval for vehicle owners is about once a year or every 10,000 kilometers. Before changing the oil, it's best for owners to check the maintenance manual to see if it supports 0W-20 engine oil to avoid blindly changing oil, which could damage the engine.
Advantages of 0W-20:
0W-20 engine oil has a low viscosity coefficient and good flowability, resulting in minimal resistance and low engine load during operation, thus saving fuel consumption.
Does 0W-20 oil damage the engine?
Generally, driving on city roads and highways shouldn't pose major issues. However, low viscosity oil is not suitable for off-road or high-emission vehicle models because it can exacerbate the engine's internal load, leading to engine damage. Since 20-weight oil has low viscosity, lubrication is enhanced, reducing engine wear.
In conclusion, if vehicle owners are unsure whether their vehicles can use low viscosity oil, they can check the vehicle's manual or consult technicians at authorized service centers. When choosing engine oil, it's essential to select within the acceptable range for the engine.
