Some companies may provide a complimentary tank of fuel with your rental. Understand the conditions, such as how much fuel you need to return with to avoid fees.

Before departing, check the interior of the rental car for cleanliness and any functional issues. Ensure equipment like the radio and air conditioning works properly.

Before booking, check for any promotional offers or discounts that may be available. Many rental companies provide seasonal deals or discounts for early bookings.

If you plan to share driving, check if the rental company allows a second driver and whether there are additional fees. Some companies offer free second driver options under certain conditions.

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.

If you're looking for extra comfort or features, ask about upgrade options at the rental counter. Often, discounted upgrades are available at pickup.

Before you finalize your booking, see if the rental agency offers free cancellation. This can be helpful if your travel plans change unexpectedly.

To evade additional charges, return the rental car on schedule. Familiarize yourself with the agreed return time to prevent any surprises.
