Look up fuel prices in the area where you'll return the vehicle. Refueling at a local station is often more economical than paying rental company rates.

When renting a car, understand the fuel policy. A 'Full-to-Full' policy means you return the car with a full tank, while 'Same-to-Same' means you return it with the same level of fuel. Full-to-Full is often more cost-effective.

Some rentals have mileage limits, while others provide unlimited mileage. Review these policies carefully to avoid unexpected charges.

Many rental firms prefer credit cards and may not accept debit cards for payment. If you're using a debit card, confirm the company's policies before making a reservation.

Note that some rental companies impose age restrictions or additional fees for drivers under 25. Always verify the age policy when booking.

Before renting a car, check if your personal car insurance covers rental losses. Many personal auto insurance policies and credit cards offer coverage for rentals, which could save you from extra insurance fees.

If you have a specific vehicle model in mind, consider rentals that guarantee the car type you want. This avoids surprises at pickup when you receive an alternative vehicle.

Before you book, review the rental agreement for any hidden fees, such as airport surcharges, additional driver costs, or penalties for late returns. Awareness helps in budgeting appropriately.
