Ways to save on petrol

From clever planning to easy car tweaks, read these smart, simple ways to help your petrol go further and save you money every time you drive.

19 March 20264 min read

Petrol prices are notorious for going up and down, and for many of us, every bit counts. The good news? There are loads of simple, forward thinking ways to help your fuel go further.

Here are some easy tips to try on your next trip.

Plan ahead

A little planning can make a big difference. Cars use more fuel when they're stuck in traffic or stopping and starting, so whether you're heading to work or going on holiday, try to plan your route ahead of time.

Use apps like Google Maps or Apple Maps to pick the quickest route and get real-time traffic updates. Avoid peak times such as school pick-up or the start of a long weekend. Leaving a little earlier or later can save both fuel and time.

If you're running errands, group them into one trip. Cold engines use 20% more fuel1, so fewer short drives can help you save.

Lighten the load

Extra weight means extra fuel. Clear out anything you don't need in the boot and take off the roof racks when they're not in use. They add drag and can increase fuel use, especially on the motorway.

The same goes for bike racks. They're handy but they can make the car thirsty!

Use air con wisely

Air conditioning is great on hot days but blasting it can use up to 10% of your fuel.1

When you're driving around town, open the windows to stay cool without using the air con. On the motorway, close the windows and use the AC. It reduces drag and keeps your fuel use steadier.

Keep a steady speed

Smooth driving is one of the easiest ways to save fuel. When we drive over the speed limit or brake hard, our cars can use up to 10% more fuel.1

Try using cruise control on long, open stretches to keep your speed steady and your ride relaxed.

Check your tyre pressure

Low tyre pressure makes your tyres work harder, which can use more fuel and be unsafe. Keeping them well-inflated elps your car roll easier, so your engine doesn't have to work as hard.

Try a hybrid or fuel-efficient model

If you're looking for a new car, hybrid and fuel-efficient petrol models are becoming more common in New Zealand. They're an easy way to cut your fuel use without changing how you drive.

Hybrids recharge through regenerative braking, which means the car recovers energy when you slow down and uses it to help power the engine. It's a smart way to save fuel on those everyday stop-and-go trips.

Newer petrol engines are getting smarter too, with tech that helps you get more out of every tank.

Planning to go electric one day? We've put together a simple guide on electric vs hybrid cars to help you compare your options.

Use apps to track your fuel use

There are handy apps that help you monitor how you drive, how much fuel you're using and where to find the cheapest fuel. Gaspy is a popular NZ-based app that monitors fuel prices and shows you the cheapest options in your area. Fuelio is a useful app to track fill-ups, mileage log, fuel consumption and GPS location. It's a win-win.

Walk, bike or take public transport

The ultimate fuel-saving tip? Leave the car at home now and then. A short walk, quick bus ride or bike trip is cheaper and healthier. And it can save you a surprising amount over a year!

Get the right cover for your car

While you're finding smart ways on fuel, it's also worth thinking about how you look after your car. A car that's well-maintained usually runs better, and having the right cover can help to protect you when the unexpected happens.

With Tower, you can choose the car insurance cover that suits you. From Comprehensive cover for all the bells and whistles, to Third party, fire and theft, or Third party if you only need the basics, we've got options to fit your needs and budget.
