Does Using Antifreeze Engine Oil in Summer Affect the Car?
2 Answers
Using antifreeze engine oil in summer does not affect the vehicle. Relevant information is as follows: 1. Antifreeze Engine Oil: Antifreeze engine oil has low viscosity and poor heat dissipation, so it is best not to use it in summer, as it can easily cause engine overheating and lead to cylinder scoring. However, most engine oils nowadays are all-season oils, and you can choose the oil based on your vehicle model without encountering many issues. 2. Antifreeze Lubricating Oil: Winter oil, also known as antifreeze lubricating oil. As the name suggests, lubricating oil ensures that the car continues to receive the necessary care during the cold winter. Compared to regular oil, antifreeze engine lubricating oil needs to maintain the normal flow of lubricating oil molecules at low temperatures.
After driving for so many years, I've found that using antifreeze engine oil in summer is generally fine, as most oils nowadays are multi-grade oils suitable for all seasons. However, if you use pure antifreeze winter oil, the viscosity might be too high under summer heat, leading to insufficient engine lubrication, resulting in increased noise or overheating that accelerates wear. From my experience, high summer oil temperatures can make antifreeze components counterproductive, thinning the oil film and reducing lubrication. It might be okay for a short while, but long-term use could lead to increased fuel consumption or engine failure. For safety, I always check the SAE rating during oil changes, opting for universal oils like 5W-30, and take the opportunity to inspect the cooling system. Relatedly, summer maintenance shouldn't focus solely on oil; cleaning the fan and radiator is also essential to prevent overheating issues.
