Should I Change to Antifreeze Engine Oil in Winter?
2 Answers
It is advisable to switch to antifreeze engine oil in winter as it has lower viscosity and can protect the engine during cold months. Antifreeze Engine Oil: Antifreeze engine oil has very low viscosity and poor heat dissipation, making it unsuitable for summer use as it may cause engine overheating and cylinder scoring. However, most engine oils available today are all-season oils, and selecting the appropriate oil based on your vehicle model generally won't cause significant issues. Antifreeze Lubricating Oil: Winter-grade oil, also known as antifreeze lubricating oil, is designed to ensure your vehicle receives proper care during the cold winter months. Compared to regular oils, antifreeze engine lubricating oil must maintain normal molecular flow at low temperatures.
I've been driving for almost thirty years, and my hometown is in Heilongjiang, where winters are extremely cold, so car maintenance requires extra attention. Winter temperatures often drop below zero, so it's essential to switch to antifreeze engine oil. I use the 5W-30 grade, which makes starting the engine much easier. Summer oil is thicker, while winter oil is thinner for better fluidity—otherwise, the car won't start in the morning. Pushing the car is not only a hassle but also risks damaging the engine. Once, I forgot to change the oil, and on a freezing day, my car broke down, costing me nearly two thousand yuan in repairs. Since then, I’ve made it a habit to visit the garage before October every year to check and replace the oil, as well as test the antifreeze concentration to ensure it can withstand low temperatures. I also check the battery and tire pressure to prevent accidents on slippery winter roads. It doesn’t cost much but makes driving much smoother and safer. Don’t ignore the manual—different cars have different requirements. Developing good habits saves time and trouble in the long run.
