Cheap AVIS Car Rentals at Oslo Gardermoen Airport, OSL

Before booking, review the rental agreement for any hidden fees such as airport surcharges, additional driver fees, or late return penalties. Understanding these can help you budget more effectively.

Many rental companies require payment by credit card and may not accept debit cards. If you only have a debit card, check the rental company's payment policies in advance and look for suitable options.

Research fuel prices in the area where you'll return the vehicle. Filling up at a local station may be cheaper than paying for fuel through the rental company, especially if they charge higher rates.

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.

Allow for possible delays at the rental desk, particularly during busy travel times.

Ask if there are extra charges for picking up at the airport versus off-site locations.

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.

Before leaving the rental location, inspect the car for any existing damage and ensure it’s documented. Take photos if necessary to avoid disputes when returning the vehicle.
