The top mistake drivers make when starting their car that could seriously damage it, according to a mechanic

2. Increased Risk of Engine Damage
In extreme cases, especially in cold weather, aggressive revving can cause scoring, overheating, or even bearing failure.

3. Stress on Turbocharged Engines
If your car has a turbocharger, the risks are even higher. Turbos spin at extremely high speeds and need proper oil flow before being pushed hard.

4. Reduced Engine Lifespan
Consistently revving a cold engine may not cause immediate failure, but it can significantly shorten the life of key components — leading to costly repairs down the line.

What Mechanics Recommend Instead

You don’t need to let modern engines idle for long periods, but you should give your car a moment to prepare itself before driving.
