Winter in Lviv — it’s not just snow and traffic jams, but also a daily challenge for the car. Frost, moisture, salt on the roads, and short trips create ideal conditions for engine wear. That’s why the issue of warming up the engine in winter generates so many debates: some warm up the car for 20 minutes, others drive immediately. Where’s the truth?

Experts from Autopark-Service in Lviv explain how to warm up the engine properly — without damaging the engine’s lifespan and wallet.

Why the Engine Suffers More in Winter

After a cold start:

  • oil is thicker and takes longer to reach all the components;
  • metal parts have different clearances;
  • fuel burns worse;
  • the turbo and automatic transmission work in “cold” mode.

The first few minutes after starting are the most critical for the engine.

Myths about Engine Warm-Up

Myth 1: “You need to warm up for 10-20 minutes at idle”

In reality, prolonged idling:

  • increases fuel consumption;
  • promotes carbon buildup;
  • does not warm up the gearbox and transmission.

Myth 2: “Modern cars don’t need to be warmed up”

Yes, electronics have become smarter, but oil and metal are still important. A cold start without warming up — a direct way to engine wear.

Myth 3: “The harder you press the gas — the faster it warms up”

Sudden loads on a cold engine damage the pistons, turbo, and cylinder head.

How to Properly Warm Up the Engine in Winter

1. Start the engine and let it run for 30-90 seconds

This is enough for the oil to start circulating.

2. Start driving smoothly

For the first 3-5 minutes:

  • do not exceed 2,000-2,500 rpm;
  • avoid sudden accelerations;
  • do not activate Sport mode.

3. Warming up happens while driving

This is how the engine, gearbox, and turbo warm up evenly and safely.

Features of Diesel Engine Warm-Up

Diesel engines in Lviv need more attention in winter as they warm up more slowly, are sensitive to fuel quality, and often have DPF and EGR systems that are especially vulnerable in the cold period. Therefore, it’s important to regularly go for diesel engine repair and preventive diesel service to avoid expensive breakdowns in winter.

Recommendation: after starting — 1 minute, then a calm drive for 5-10 minutes.

What Happens If You Don’t Warm Up the Car

  • accelerated engine wear;
  • increased fuel consumption;
  • turbo issues;
  • carbon buildup;
  • faster transmission wear.

When to Go to Autopark-Service

If:

  • the engine is misfiring after starting;
  • the RPMs are fluctuating;
  • there’s a fuel smell;
  • fuel consumption has increased;
  • the Check Engine light is on.

Experts at Autopark-Service in Lviv will diagnose and check the cold start system.

Conclusion

Proper warming up is not standing for 20 minutes, but giving the engine a minute and driving calmly. This approach will save the engine’s lifespan, reduce costs, and prevent expensive repairs.
