Is Your Gas Mileage Getting Worse?
Are you making more frequent trips to the gas station? A sudden drop in your car's fuel economy can be frustrating and costly. It's a common issue we see where our certified technicians help drivers get to the bottom of poor gas mileage.
Your car's fuel efficiency is affected by everything from your driving habits to a variety of maintenance issues. Ignoring a decline in MPG isn't just bad for your wallet; it can be a sign of a larger problem.
Top Reasons for a Drop in Fuel Economy
A decrease in your vehicle’s gas mileage is often a warning sign that something isn't working as it should. Here are some of the most frequent culprits we find during our diagnostics:
Underinflated Tires: This is one of the easiest issues to fix. Tires with low pressure increase rolling resistance, forcing your engine to work harder and burn more fuel. Regularly checking your tire pressure can significantly improve your MPG.
Clogged Air Filter or Faulty Sensors: A dirty engine air filter restricts airflow, which can cause your engine to burn more fuel to compensate. Similarly, a failing Mass Airflow (MAF) sensor or Oxygen (O2) sensor can disrupt the air-fuel mixture, leading to inefficiency and a lit check engine light.
Worn Spark Plugs: Spark plugs are vital for igniting the fuel-air mixture. Old or worn-out spark plugs can lead to incomplete combustion, wasting gas and reducing engine power.
Fuel System Problems: Issues like clogged fuel injectors or a faulty fuel pressure regulator can cause your engine to run too rich, burning excess fuel and tanking your gas mileage.
Aggressive Driving Habits: How you drive has a huge impact on fuel efficiency. Frequent hard acceleration, aggressive braking, speeding, and excessive idling all contribute to lower MPG.
Incorrect or Old Engine Oil: Using the wrong type of oil or neglecting oil changes can increase friction within your engine, forcing it to work harder and consume more fuel.
How We Can Help Improve Your MPG
If you've noticed a significant and persistent drop in your fuel economy, it's time to get a professional diagnostic. Our ASE-certified technicians will perform a comprehensive check to identify the root cause, including:
- Engine Performance Scan: We'll check for any trouble codes and analyze engine performance.
- Fuel System and Sensor Testing: We'll inspect your fuel injectors, O2 sensors, and other critical components.
- Tire and Brake Inspection: We'll ensure your tires are properly inflated and that your brakes aren't dragging, which can also reduce fuel efficiency.
- Routine Maintenance Review: We'll check your oil, air filters, and spark plugs to make sure they're in top condition.
Don’t Let Poor Fuel Economy Cost You More
You shouldn't have to guess why you're spending more at the pump. A drop in MPG is a clear sign that your vehicle needs a check-up.
