Diesel engines are known for their durability over many miles. But even a diesel engine may sometimes experience loss of power, especially when it’s hot or carrying a heavy load. If this is happening to your diesel vehicle, you may be faced with some form of diesel repairs, either minor or major.

So what causes a diesel engine to lose power? Here is a list of the five main causes:

  1. Clogged Fuel Filter. The fuel filter removes impurities from the fuel to keep them from entering the engine. A clogged fuel filter cannot properly filter out contaminants.
  2. Clogged Exhaust Pipe. The exhaust system, made up of the catalytic converter and the muffler, reduces the amount of pollution produced from exhaust fumes. A clogged exhaust pipe will lessen the power of the engine.
  3. Dirty Air Filter. Engines use a mix of fuel and air to generate power. As the outside air goes through the filter, it catches dirt, debris, bugs, and other contaminants. If the air filter is dirty, the engine has to work harder to generate power.
  4. Dirty Spark Plugs. Over time, carbon deposits build up on spark plugs, leading to the misfiring of the engine.
  5. Low Compression. If the cylinder compression is too low and cannot function properly, there will be less power from the engine.

Here are a few easy solutions to help restore power to your diesel engine:

  1. Change the oil – Oil can become dirty and lose its effectiveness if not regularly maintained, making it harder to flow through the engine. This can lead to clogs and other problems, causing the engine to work harder to circulate the thickened oil. Changing your oil regularly is one of the easiest ways to prevent power problems.
  2. Use high-quality fuel – Lower-grade fuel has more risk of contamination, so invest in the highest quality fuel possible.
  3. Clean and/or change your filters – The fuel and air filters have a big impact on how your engine runs, so make sure to service them regularly to prevent buildups and clogs. High-quality filters are worth a few extra dollars
  4. Check out strange problems – If your diesel engine is acting strange and you don’t know what the problem is, get help from a diesel professional. It can save you the time and expense of dealing with bigger diesel repairs down the road.
