Why does my car run less gas mileage?
This is because the fuel injectors are responsible for putting fuel into the engine. If there is a leak of some sort, then less fuel will make it to the engine, and then in turn make it run less efficiently. Having your air conditioner on causes a lot of gas to be wasted in powering the system.
