How to Save Fuel in New Zealand
Improving fuel efficiency does not require major changes. Small driving and maintenance habits can make a noticeable difference.
Practical fuel saving tips
- Drive smoothly and avoid harsh acceleration
- Maintain steady speeds where possible
- Keep tyres properly inflated
- Remove unnecessary weight from your vehicle
- Keep up with regular servicing
These steps help reduce fuel consumption and improve overall vehicle performance.
The Fuel You Choose Matters
One of the most common questions we hear is whether 91 octane can be used instead of 95. While it may seem like an easy way to save, using the correct fuel grade is important for performance and long-term reliability.
The most important rule when choosing fuel is simple: always use the octane rating specified for your vehicle.This can usually be found on the inside of your fuel filler flap or in your owner’s handbook.
In some vehicles, you can use a higher octane however, using a lower octane fuel than recommended may seem like a way to save in the short term, but over time it can affect performance and potentially damage your engine.
Our Giltrap Group aftersales teams see this most often across vehicles from brands such as Audi, Volkswagen, Škoda, CUPRA, Land Rover, Volvo, Lexus and Porsche, where higher octane fuel is part of how the engine is designed to operate.
Some vehicles, including selected models from Kia, Geely and Lexus, are engineered to run on 91 octane petrol. However, the key is always to follow your vehicle’s specific requirement to ensure optimal performance and long-term reliability.

Why using the correct fuel matters
• Maintains smooth and consistent engine performance
• Supports fuel efficiency over time
• Reduces strain on key engine components
• Helps protect long term engine durability
Using lower octane fuel in engines designed for 95 or above may lead to reduced performance and increased wear over time. This means choosing the right fuel is not just about performance, it is about protecting your investment.
What brands and petrol models can take 91 octane
- Selected Kia petrol models: Stonic, Seltos, Sportage and Sorento
- Geely Starray
- Lexus UX 200
