EPA tests are designed reflect "typical" driving conditions and driver behavior, but several factors can affect MPG significantly:

  • How & Where You Drive
  • Vehicle Condition & Maintenance
  • Fuel Variations
  • Vehicle Variations
  • Engine Break-In

Therefore, the EPA ratings are a useful tool for comparing the fuel economies of different vehicles but may not accurately predict the average MPG you will get.
