Can You Use Regular Engine Oil in Winter?

Regular engine oil typically thickens in cold weather, which makes it harder to properly lubricate your engine’s components. Worse, the strain on your engine will worsen the wear and tear of its parts, cutting your engine’s lifespan while impacting your vehicle’s performance and fuel consumption rates. The result? More expensive fuel and maintenance for a vehicle that can’t run as well as it did before.

Which Engine Oil is Best for Winters?

Winter-grade motor oil is designed to maintain optimal viscosity in cold temperatures, allowing it to flow more freely and offer better protection for your engine. By using oil with a lower “W” rating (such as 5W-30 instead of 10W-30), you’ll ensure that your engine is well-lubricated and protected from the effects of extreme cold.

Check your vehicle’s manual for recommended viscosities based on seasonal temperatures. The prairie’s temperatures can drop well below freezing, so a multi-viscosity oil with a low “W” rating, like 0W-20 or 5W-30 is ideal. These oils are specially formulated to provide effective lubrication in cold weather, reducing engine strain and helping your vehicle start more smoothly in freezing conditions.

When to use Winter Oil

Just like changing over to winter tires, it’s best to switch to winter motor oil before temperatures consistently dip below 7°C (typically late October or early November). By making the change early, you’ll protect your engine from the first wave of freezing weather and prevent unnecessary wear.
