Ford Explorer 18.6 gal 480-530 miles

Factors Affecting Fuel Range

  • Driving habits: Aggressive acceleration reduces efficiency.
  • Load weight: Heavier cargo or towing lowers MPG.
  • Terrain: City driving drains fuel faster than highway.
  • Maintenance: Clogged filters or old spark plugs hurt performance.

How to Check Your Highlander's Fuel Capacity

  1. Refer to the owner's manual (Section 5: Specifications).
  2. Look for the fuel tank label inside the driver's door jamb.
  3. Use the trip computer (if equipped) to estimate remaining range.
