Can Winter Engine Oil Be Used in Summer?
1 Answers
It is not recommended to use winter engine oil in summer. Here are the detailed explanations: 1. If winter engine oil is used in summer, due to its low viscosity, the formed oil film will be thinner and less stable. This will increase the friction and wear between engine components, potentially damaging the engine and shortening its lifespan. 2. Additionally, the weaker sealing performance may allow engine oil to seep into the combustion chamber, leading to oil burning and increasing maintenance costs. 3. Conversely, using summer engine oil in winter is also not advisable, as it may cause difficulties in starting the vehicle. As temperatures drop in winter, the viscosity of the oil increases, making it harder to flow and increasing engine resistance, which makes starting difficult. 4. When using single-grade viscosity oils like winter or summer engine oil, extra care is needed. Timely oil changes are essential to avoid potential damage to the engine. 5. Nowadays, more people opt for multi-grade (all-season) engine oil, which can be used year-round, offering greater convenience. If using full synthetic oil, it typically requires changing only once a year.
