Q: Very low fuel efficiency

asked by on

Trying to figure why I only get about 14 miles to the gallon when the average is about 24

My car has 39087 miles.
My car has an automatic transmission.

Your mileage is low compared to the EPA rating. Your vehicle was sold with a 3 yr/36,000 mi basic, 5 yr/60,000 mi powertrain warranty. In the event that there is an engine or transmission problem that accounts for the low fuel efficiency that you are experiencing, you should make a warranty claim to see if there is something that the dealer can do to resolve this.

You can maximize mileage by: keeping the tires adequately inflated; ensuring vehicle wheel alignment is correct; check for stuck brake caliper(s); maintain consistent vehicle speed; make sure engine temperature is in normal range and not too low due to a stuck open cooling system thermostat; check oxygen sensors as worn out or faulty oxygen sensors will cause higher fuel consumption; check for worn out spark plugs; low engine compression due to mechanical defects; slipping components in the transmission; dirty or leaking fuel injectors; defects in EGR system; exhaust restrictions; and excess weight in vehicle. If mileage does not improve after verifying all of the foregoing, or if you simply want all the foregoing inspected, please request a vehicle fuel efficiency diagnostic and the responding certified mechanic will get this issue investigated and resolved for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you
