How Long to Warm Up Your Car in Winter

Winter in Calgary brings cold temperatures, icy roads, and an important question for drivers: How long should you warm up your car before hitting the road? Many Calgarians grew up with the idea that warming up your car for several minutes in winter is essential to protect your engine. However, with advancements in automotive technology, this belief may need a fresh look.

Let’s understand the nuances of warming up your car in Calgary’s frigid winters, ensuring your vehicle performs optimally while conserving time, fuel, and money.

Why Warming Up Your Car Matters

When temperatures drop, so does the efficiency of your car’s engine. At low temperatures, engine oil becomes thicker and takes longer to circulate. Warming up the engine ensures that:

• Oil flows properly: Adequate lubrication reduces wear and tear.
• Engine components stabilize: Metals expand and contract due to temperature changes, and warming helps normalize this process.
• Cabin comfort improves: Heating systems require the engine to reach a certain temperature to function effectively.

However, modern vehicles have features that make long idling less necessary than in older models.

The Reality: How Long Do You Really Need?

For Modern Cars

Most vehicles built after the mid-1990s use fuel-injection systems, which adjust air-fuel mixtures automatically to accommodate cold weather. This means your car doesn’t need extended idling to warm up.

• Ideal Warm-Up Time: 30 seconds to 1 minute.
  After starting your engine, give it about 30 seconds for the oil to circulate, then start driving gently. Your engine will warm up faster through driving than idling.
