When fuel prices keep climbing, every trip to the petrol station can feel like another hit to the household budget.

We may not be able to control the price at the pump, but we can control how efficiently we use the fuel we buy. And the good news is that you don’t need to buy a new car or completely change your lifestyle to make a difference.

A few simple driving and vehicle-maintenance habits can help your tank last longer—and those small savings can add up over a year.

Here are 11 practical ways to make your fuel go further.

1. Drive smoothly

Fast acceleration followed by heavy braking uses more fuel than driving at a steady pace.

Look further ahead, ease off the accelerator earlier when approaching intersections or slower traffic, and accelerate gradually.

Besides saving fuel, smoother driving can also reduce wear on your brakes and tyres.

2. Watch your speed

The faster you travel, the harder your engine has to work against air resistance.

On open roads, keeping to the speed limit—and avoiding unnecessary bursts of speed—can make a noticeable difference to fuel consumption.

It can also make for a more relaxed journey.

3. Check your tyre pressure

Under-inflated tyres create additional rolling resistance, which means the engine has to work harder.

Check your tyre pressures regularly, particularly before a long journey.

The recommended pressure is normally listed inside the driver’s door, near the fuel flap or in the vehicle handbook.

Correct tyre pressure also improves handling and helps your tyres last longer.

4. Use Gaspy to compare fuel prices

Fuel prices can vary considerably between service stations, even within the same area.

Before filling up, check the Gaspy app to compare nearby petrol and diesel prices. Gaspy uses crowd-sourced information from NZ motorists to help users find cheaper fuel in their area.

You don’t need to drive across town to save a few cents a litre—the extra distance could wipe out the saving—but if there is a cheaper station already close to your route, it can make sense to use it.

Over a year, regularly paying a little less per litre can add up.

5. Take unnecessary weight out of the car

How much is permanently travelling around in your boot?

Sports equipment, tools, boxes and other items gradually accumulate—and your engine is carrying that extra weight everywhere you go.

Have a quick clean-out and remove anything you don’t regularly need.

Also consider removing roof racks, bike racks or roof boxes when you’re not using them. They add wind resistance as well as weight.

6. Combine several trips into one

A little planning can save surprisingly many kilometres.

Instead of making separate journeys to the supermarket, pharmacy, bank and other appointments, see whether you can combine several errands into one trip.

This is particularly useful for short journeys because vehicles are generally less efficient while the engine is cold.

7. Avoid unnecessary idling

Sitting stationary with the engine running is quite literally burning fuel without going anywhere.

If you’re safely parked and expect to wait for a while, switch the engine off.

If your vehicle has automatic stop-start technology, leaving it activated can also help reduce unnecessary fuel use during stop-start city driving.

8. Keep your vehicle serviced

A vehicle that is properly maintained generally runs more efficiently.

Keep up with servicing, oil changes, air filters and wheel alignment rather than waiting until something goes noticeably wrong.

Regular servicing isn’t just about fuel economy—it may also help identify smaller problems before they turn into expensive repairs.

9. Use cruise control when it makes sense

On suitable open roads, cruise control can help maintain a consistent speed and reduce unnecessary acceleration.

It isn’t appropriate everywhere, particularly on winding or congested roads, but on long, relatively flat stretches it can make both your driving and fuel use more consistent.

10. Think before making very short trips

Not every journey needs the car.

Could a short trip occasionally be walked or cycled? Could two family members coordinate their errands? Could you carpool for a regular activity?

You don’t need to give up your vehicle. Simply eliminating a few unnecessary journeys each week reduces both fuel use and kilometres travelled.

11. Make fuel part of your household budget

Fuel is one of those expenses that can quietly creep upward.

Rather than simply filling the tank whenever it is empty, look at what your household actually spends on petrol or diesel each month.

If fuel costs have risen, don’t ignore the increase. Adjust the budget somewhere else rather than allowing the extra spending to disappear onto a credit card or overdraft.

This is also a good reminder that small savings matter.

Saving $10 here and $20 there may not feel dramatic, but repeated every week across groceries, power, insurance, subscriptions and fuel, those savings can add up to thousands of dollars over time.

Small changes can make a real difference

None of these ideas will bring fuel prices down.

But they can help you use less of what you are paying for—and, with tools such as Gaspy, potentially pay less per litre as well.

And that is really what good money management is about: concentrating on the things you can control.

At Bricks & Mortgages, we often find that when people review their mortgage, it is also a great opportunity to look at the wider household budget.

Even relatively small improvements to monthly cash flow can sometimes be redirected toward debt reduction, an emergency fund or getting the mortgage paid off sooner.

If it has been a while since your mortgage and household finances had a proper review, we’d be happy to help.
