What Type of Engine Oil Should Be Added in Northern Winters?

In northern winters, SAE 0W engine oil should be added, such as 10W40, 5W40, or 0W40 models. The SAE viscosity classifications for winter engine oils are: 0W, 5W, 10W, 15W, 20W, and 25W. The symbol 'W' stands for winter, and the smaller the number before 'W,' the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the applicable minimum temperature. Northern winters are relatively cold, so it is advisable to choose engine oil with slightly lower viscosity. Engine oil, also known as engine lubricant, serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. Engine oil consists of two main components: base oil and additives. The base oil is the primary component of lubricating oil, determining its basic properties, while additives compensate for and improve any deficiencies in the base oil's performance, making them an essential part of lubricating oil.

I've been driving for twenty years, and the selection of engine oil in northern winters really requires caution. It's recommended to use low-viscosity winter engine oil, such as 0W-30 or 5W-40 series, which keeps the oil flowing even at temperatures dozens of degrees below zero, ensuring faster and smoother engine starts. I remember when I first bought my car, I once used summer oil, and the oil was so thick that the morning ignition felt like it was jamming, almost damaging the components. Since then, I've always insisted on using synthetic oil—better fluidity, less wear, and more fuel-efficient. Before winter arrives, I always go to a professional shop for inspection and replacement, and also check the antifreeze. The key is not to just look for cheap products; good-quality oil may be more expensive, but it ensures safety. When temperatures drop, choosing the wrong oil can cause many problems, so early preparation is crucial.

When taking my kids to school, I pay extra attention to winter driving safety. In cold northern climates, it's best to use engine oil with a 5W rating for better fluidity and easier engine starts—options like 5W-30 or 0W-20 are affordable yet practical. Always visit authorized repair shops for oil changes, as they can recommend the right type for your car model, avoiding DIY mishaps. Synthetic oil lasts longer and offers peace of mind in icy conditions. I still remember my neighbor using the wrong oil last winter—his car broke down, leaving the kids freezing. Also, check tire pressure and battery regularly; safety is no small matter. Keeping emergency tools on hand ensures stable winter trips.

Just got my driver's license last year and as a newbie on the road, I've been pondering about engine oil. For northern winters, 0W oil is the most suitable, like the low-viscosity type 0W-40, which allows the oil to flow faster at low temperatures, making engine starts much easier. Tried standard oil before, but it was too thick, causing more vibration and higher fuel consumption. Consulted an experienced driver friend who recommended synthetic brands like Mobil for cold resistance and engine protection. When changing oil in winter, it's also a good time to check the car's condition, with minor maintenance costs being quite affordable. Simply put, choosing the right oil means fewer worries about car startups.
