Answer
Fuel policies can vary by rental company, so it's important to ask about them upfront. The most common policy is 'full-to-full', where you pick up the car with a full tank and return it full. This is usually the most cost-effective option.
• Some companies might offer 'pre-purchase' fuel options, where you can pay in advance for a full tank but won't get a refund for any unused fuel. This can be convenient, but often ends up being more expensive if you don't use the full tank.
• Make sure to check the fuel type required for the vehicle you are renting. Most cars in Thailand run on unleaded petrol, but always double-check to avoid any mishaps at the pump.
Practical Chiang Mai planning note: Confirm current routes, fares, operating hours and pick-up arrangements before travelling. Build in extra time for traffic, weather and festival road closures, and keep the destination name or map pin available in Thai for drivers when practical. Prices and fares change, so request the current amount before committing.
