Inefficient driving is one of the leading factors in the mileage your vehicle achieves. Insufficient driving includes:

  • 1.Fast acceleration or flooring your vehicle
  • 2.Speeding
  • 3.Hard braking

Driving like this can affect your gas mileage by as much as 33% on the highway, or 5% during city driving. A driver feedback tool that most insurance companies offer as a way to lower your rates is a good way of monitoring how efficiently you’re driving is.

Removing any excess weight from your vehicle can decrease your gas consumption. It is estimated that for every 100 lbs. of extra weight in your vehicle can decrease fuel economy by up to 2%. Also avoid having a rooftop cargo box/tray because it significantly increase drag on your vehicle which will use more gas.

Using Cruise Control helps fuel economy because you aren’t going up and down in speed and/or RPM. Driving your vehicle in overdrive helps with fuel consumption because it lowers engine speed.

5 parts on your car that can cause bad gas mileage:

  • 1. Not changing your oil on time. When you don’t change your oil following the manufacturers maintenance guide can cause oil to become sludgy which makes your rotating assembly work harder to generate power causing an increase in gas consumption
  • 2. Make sure your tires are inflated to the tire manufacturers suggested PSI, under inflated tires need more engine power to rotate, meaning your using more gas.
  • 3. Air flow sensor and O2 sensor measure the air flow entering and exiting your engine, when they go bad, the readings are inaccurate which can increase the amount of fuel the computer sends into the engine.
  • 4. A dirty or old air filter can block the amount of air being pulled into the engine, this will lean your motor out and will dump more fuel into the system to make up for it.
  • 5. Spark plugs control the mixture of air and fuel during ignition, new spark plugs run cleaner which will make your car run more efficiently.
