Why does the Cruze use 0W20 engine oil?
2 Answers
Because 0W20 engine oil has lower viscosity, which can reduce fuel consumption. Here is more information about engine oil: 1. Engine oil is called the blood of the engine. Without engine oil, the engine cannot operate normally. Engine oil not only lubricates but also cleans, seals, buffers, prevents rust, and dissipates heat in the engine. 2. When the engine is running, engine oil forms a thin film on the surfaces of various components inside the engine, preventing direct contact and friction between them. If engine components directly contact each other and cause friction, it will accelerate engine wear and may also lead to engine overheating.
When using the Cruze, I learned that it recommends 0W-20 engine oil primarily to optimize engine performance. During winter starts, the 0W part indicates that the oil has excellent fluidity at low temperatures, allowing it to quickly lubricate all components and reduce wear. The 20 viscosity number means the oil remains thin at high temperatures, resulting in less engine friction and naturally saving fuel. This is particularly important for the Cruze because it features a compact engine design, and using this oil can improve fuel efficiency by over 10%. In my daily driving, I feel the engine responds more sensitively, especially during cold morning starts, which are smoother. However, it's important to change the oil regularly—typically every 5,000 kilometers or 6 months—to maintain optimal performance. Modern cars, including the Cruze, use low-viscosity oil for greater efficiency and environmental friendliness.
