Are Diesel Cars Bad for Short Journeys? What You Need to Know

Discover why diesel cars are not ideal for short trips and learn about better alternatives for short-distance driving.

Video transcript

Diesel cars are typically less suited for short journeys because their diesel particulate filters (DPFs) require longer drives to reach the temperatures needed to burn off soot and particulates. Frequent short trips can lead to DPF clogging and engine issues. If you primarily make short journeys, consider a petrol, hybrid, or electric car for better efficiency and reduced maintenance problems.

Questions and answers

  1. Why are diesel cars not suitable for short journeys?

    Diesel cars' particulate filters require high temperatures achieved during longer drives to clear soot; frequent short trips prevent this, causing clogging and engine issues.

  2. What happens if the diesel particulate filter (DPF) gets clogged?

    A clogged DPF can lead to reduced engine performance, increased emissions, costly repairs, and potential engine damage.

  3. Which cars are better for short journeys than diesel?

    Petrol, hybrid, and electric cars are generally better suited for short trips due to their engine design and lower risk of particulate filter issues.

  4. How can I maintain a diesel car if I frequently make short trips?

    To maintain a diesel car with short trips, occasionally drive at sustained higher speeds to allow the DPF to reach cleaning temperature, or consider professional DPF cleaning.
