What Are the Effects of Short-Distance Driving on a Car?

Frequent short-distance driving is harmful to the engine and increases fuel consumption. The specific details are as follows: Short-distance driving increases fuel consumption: Short trips within 2 kilometers not only consume more fuel but also easily lead to carbon deposits. More importantly, when the engine is cold, the oil flows back to the oil pan. During a cold start, the lubrication surfaces experience dry friction. The higher the oil viscosity and the poorer its low-temperature fluidity, the longer it takes for the oil pump to deliver oil to the lubrication surfaces, resulting in more severe friction. Frequent cold starts exacerbate this issue. Short-distance driving affects engine lifespan: Before the oil is pumped to the lubrication surfaces, wear is severe. Additionally, to quickly reach operating temperature, the engine control unit injects extra fuel into the cylinders to accelerate combustion. This not only wastes fuel but also leads to incomplete combustion, causing valve coking and significantly reducing the engine's lifespan.

Over the past few years, I've only been driving short distances daily for commuting, just a few kilometers each time, and I've noticed it has quite an impact on the car. The car often has difficulty starting, the battery keeps losing charge, and its lifespan shortens. The engine temperature doesn't rise sufficiently, the oil gets contaminated quickly, and during oil changes, it looks black and dirty. Additionally, the braking system doesn't warm up properly, making it more dangerous in winter, with less responsive emergency braking. I later learned that it's best to take a long drive weekly to warm up the engine and reduce these issues.

As someone who has worked on cars, I believe short-distance driving can be quite damaging to a vehicle. The engine doesn't have enough time to warm up, leading to increased carbon buildup and faster wear on piston rings and bearings. The battery is also affected, as insufficient charging results in weak starts. Additionally, the quality of the engine oil deteriorates, and the efficiency of the transmission system decreases. Over time, these issues can lead to higher maintenance costs. Personally, I make it a habit to regularly check the cooling system and emissions to prevent problems from worsening.

I love playing with cars, and short-distance driving has a noticeable impact on performance. Cold starts cause significant engine wear, incomplete fuel combustion, and sluggish acceleration. The exhaust system doesn't warm up properly, increasing the risk of catalytic converter failure. I recommend taking a monthly highway run to balance these effects and ensure smoother driving.
