The problem stems from the way in which the EPA tests your vehicle, to determine what the correct MPG for city and highway should be. Here are some problems with their methods:

  • EPA highway cycle assumes an average speed of 48 mph and a top speed of 60 mph, which isn't realistic
  • EPA data shows that we spend about 62% of our time in urban driving (congestion), yet for testing they still assume only 55%
  • Acceleration rate in the EPA test cycles is 3.3 mph per second, about the same as going from zero to 60 mph in about 18 seconds, also not typical of drivers
  • Performed between 68 and 86 degrees Fahrenheit. Most states frequently experience weather conditions outside this range and fuel economy can be significantly affected as a result
  • Performed with the air conditioning off
  • City test cycle is 7.5 miles long. EPA’s own data, however, indicate that average trip lengths may be only 5 miles long, with typical trips as short as 2.5 miles. Shorter trips often mean lower fuel economy because the engine does not have time to warm up and operate efficiently
  • Fuel economy information is not required for light duty trucks

  • Avoid driving on hilly or mountainous terrain if possible: Driving hilly or mountainous terrain or on unpaved roads reduces fuel economy most of the time. The EPA test assumes vehicles operate over flat ground.

  • Do not use 4-wheel drive if it is not needed. 4-Wheel drive reduces fuel economy. Four-wheel drive vehicles are tested in 2-wheel drive. Engaging all four wheels makes the engine work harder and increases crankcase losses.

  • Maintain your Automobile: A poorly tuned engine burns more fuel, so fuel economy will suffer if it is not in tune. Improperly aligned or under inflated tires can lower fuel economy, as can a dirty air filter or brake drag.
