Do Engines Lose Horsepower Over Time?

Over time, engines can lose their power, resulting in a notable drop in performance and reduced horsepower and efficiency.

What causes loss of horsepower?

The most likely issue is a clogged fuel filter. The purpose of the fuel filter is to ensure that dirt and debris stay out of the fuel system, so over time, it may need cleaned or replaced. When the fuel filter is clogged, the fuel pump has to work much harder, resulting in a far less efficient drive.
