Understanding Potential Causes

Before we dive into potential solutions, it's crucial to understand the underlying causes that could be contributing to your car's lousy mileage. Several factors can affect fuel efficiency in vintage vehicles, including:

  • Clogged Fuel Injectors: Over time, fuel injectors can become clogged with carbon deposits, affecting the proper fuel delivery to the engine.
  • Ignition System Issues: Faulty spark plugs or ignition timing problems can lead to inefficient combustion, resulting in poor mileage.
  • Air Intake Blockages: Obstructions in the air intake system can restrict airflow, leading to an imbalance in the air-fuel mixture and decreased mileage.
  • Exhaust System Problems: A damaged or malfunctioning exhaust system can negatively impact fuel efficiency by hindering the proper expulsion of combustion gases.
