* Inconsistent Fuel Delivery: Worn injectors may not spray fuel in the optimal pattern or at the correct pressure. This leads to incomplete combustion, meaning the engine isn't using all the fuel efficiently.
* Fuel Leaks: Worn injector seals can leak fuel, wasting fuel even when the engine isn't running.
* Clogged Injectors: Over time, injectors can become clogged with deposits, restricting fuel flow and again leading to incomplete combustion.
* Increased Fuel Consumption: To compensate for the inefficient fuel delivery, the engine may need to use more fuel to maintain its power output.
Therefore, if you're experiencing poor fuel economy, worn fuel injectors should be considered as a possible cause. Other potential causes also exist, but this is a significant one.
