Many people do not realize that their muffler and exhaust system are the key to improved fuel economy. A clogged or damaged exhaust system causes back pressure in the engine. This can cost money at the gas pump.
If you have experienced a sudden drop in gas mileage, your exhaust system may be the first place that you need to look. When the exhaust system is not functioning properly, it can cause the engine to run rough, hesitate, or sputter. Even if your vehicle is not louder than usual, the problem may be in the exhaust manifold, catalytic converter, or other component of your exhaust system that would not cause loud noises.
Having your exhaust system checked regularly by the team at Bob Thomas Ford Lincoln North will keep your car running smoothly. This could save you a considerable amount over the long-term in terms of fuel efficiency.
