Key Travel Facts & Insights

  • Full-to-Full Policy (Best Value)
  • Prepaid Fuel vs Rental Company Refueling Charges

Full-to-Full Policy (Best Value)

You receive the rental car with a full tank of gas and return it with a full tank. Always fill up at a gas station within 5–10 miles of the return location and keep the receipt.

Prepaid Fuel vs Rental Company Refueling Charges

Prepaid fuel allows you to return the car empty at local pump rates, but you get no refund for unused gas. If you fail to return full without prepaying, rental companies charge inflated rates ($9–$12/gallon).
