AUBURN HILLS, MI – As fuel prices climb, Chrysler Group passes along tips to help customers maximize the fuel economy of their vehicles. While Chrysler Group is working to improve the fuel economy of its vehicles through technologies available today such as Multi-Displacement System, more efficient engines and diesel tech-nology, there are additional measures customers can take to enhance their fuel economy.

Modifying Driving Habits:

  • Slow down – every 5 mph over 65 mph can decrease fuel economy by as much as 7 percent.
  • Reduce speeds - 65 mph is much better than 75, some times improving fuel economy by more than 1 mpg.
  • Use modest acceleration when possible, minimizing "jack-rabbit" starts.
  • Prudent use of air conditioning and other accessories such as interior lighting and heated seats.
  • Use cruise control to help maintain a steady speed.
  • Limit extended idles and warm up periods – don't leave vehicles idle while running in for the cup of coffee in the morning.
  • Plan your trip to avoid rush hour, if you can, to avoid idling in traffic.

    Check Vehicle Condition:

  • Ensure proper vehicle maintenance.
  • Replace dirty air filters – a clogged air filter can reduce fuel economy as much as 10 percent.
  • Check tire pressures – tires under-inflated by just 2 PSI can reduce fuel economy as much as 1 percent.
  • Remove extra weight from vehicles – an extra 100 lbs. in the trunk or pickup box can lower fuel economy 1 to 2 percent.
  • Reduce aerodynamic drag on vehicle by taking empty cargo carriers, bike racks, ski racks, etc. off – at highway speed, 50 percent of the engine power is used to over-come aerodynamic drag.
  • Remove unused items from roof racks as a loaded roof rack can reduce fuel economy at highway speeds by as much as 5 percent.
  • Keep vehicle engine tuned up as a noticeably out of tune engine can reduce fuel economy as much as 4 percent.
  • If vehicle engine light is on, have the vehicle serviced – faulty components such as an oxygen sensor can reduce fuel economy as much as 40 percent.
