Most rental cars in New Zealand use petrol, but some larger vehicles, SUVs, vans, and campervans may use diesel. It's important to check your rental agreement and fuel label before refuelling, as using the wrong fuel can result in significant repair costs and is usually not covered by insurance.
If you're hiring a rental car in New Zealand, one of the first things to check is which fuel your vehicle requires.
While petrol vehicles are the most common, diesel vehicles are also widely used, particularly in larger vehicle categories.
The correct fuel type will be clearly indicated on the vehicle and in your rental documentation.
Do most rental cars use petrol or diesel?
Most standard rental cars use petrol.
This includes many:
- Compact cars
- Economy vehicles
- Sedans
- Small SUVs
Diesel is more commonly used in:
- Larger SUVs
- People movers
- Vans
- Some campervans
If you're unsure, always check before filling up.
How do I know which fuel my rental car uses?
There are several ways to check:
- Look for a label inside the fuel flap
- Check the rental agreement
- Review the vehicle information provided at collection
- Ask the rental company before leaving the depot
It's always worth double-checking, especially if you're unfamiliar with the vehicle.
What happens if I put the wrong fuel in the car?
Using the wrong fuel can cause serious engine damage.
If you accidentally fill a petrol vehicle with diesel, or a diesel vehicle with petrol:
- Do not start the engine.
- Contact the rental company immediately.
- Follow their instructions for roadside assistance.
Repair costs can be significant and are generally the responsibility of the driver.
Are petrol stations easy to find in New Zealand?
Yes.
Fuel stations are readily available in cities, towns, and along most major touring routes.
In more remote areas, particularly parts of the South Island, it's a good idea to refill before your tank becomes too low.
This is especially important when travelling to destinations such as Milford Sound, Mount Cook National Park, and some West Coast regions where services can be further apart.
Is petrol or diesel cheaper in New Zealand?
Fuel prices vary throughout the country and change regularly.
Diesel fuel is often cheaper at the pump than petrol, although diesel vehicles may be subject to additional road user charges depending on the rental company's pricing structure.
Your rental provider will explain any applicable charges before travel.
Do I need to return the rental car with a full tank?
Most rental companies require the vehicle to be returned with the same fuel level it had when collected.
In many cases, this means returning the vehicle with a full tank.
Your rental agreement will outline the fuel policy for your specific vehicle.
