• 1

  Use the tank-to-tank method for accurate measurements - fill completely each time

• 2

  Track fuel economy separately for city and highway driving

• 3

  Compare your results to EPA ratings to assess vehicle performance

• 4

  Seasonal variations are normal - cold weather reduces fuel economy

• 5

  Sudden drops in economy may indicate maintenance needs

• Using estimated amounts instead of actual fuel purchased

• Not filling to the same level each time for consistent measurements

• Comparing results from different driving conditions

• Expecting to match EPA estimates in real-world driving
