Petrol prices can take a big bite out of household budgets, especially for Australian families who rely on a car for school drop-offs, work, childcare and everyday activities.
With petrol prices rising sharply and in many cases jumping significantly even compared to just a month ago, families are feeling the impact every time they fill up. When fuel costs increase this quickly, it doesn’t just affect the weekly budget, it can also flow through to groceries, activities and everyday expenses.
The good news is that even small changes to your driving habits and refuelling routines can add up to real savings over time.
If you’re looking to cut costs, these practical tips can help you save money on fuel and reduce other car-related expenses, while still getting where you need to go.
Looking to cut costs across your whole household? Our guide on how to save money as a family in Australia covers groceries, power bills, kids’ costs, transport and everyday expenses.
Track fuel prices and fill up at the right time
Fuel prices fluctuate regularly, often rising before holidays or long weekends and dropping again soon after.
Track petrol prices in your area and fill up on low-price days. Use tools like the NRMA Fuel App or MotorMouth to compare prices and find the cheapest petrol nearby.
Keep your car running efficiently
A well-maintained car uses less fuel and performs better overall.
Check your tyre pressure regularly to improve fuel economy and safety. Keep your car serviced on schedule, as poor maintenance can increase fuel consumption. Maintain a steady speed and avoid rapid acceleration, which makes the engine work harder and uses more petrol.
Reduce unnecessary fuel use
Small habit changes can make a noticeable difference to fuel consumption.
Turn off your engine if you’re idling, such as during school pick-up. If your car has an auto stop-start feature, use it. Combine trips so errands and appointments are done in one journey instead of multiple short trips.
Use fuel discounts and memberships
Discounts and memberships can help lower the cost of filling up.
If you drive frequently, a Costco membership can offer cheaper fuel prices. Even if you don’t shop for groceries there, fuel savings alone can make the membership worthwhile for some households.
If you’re an NRMA member, take advantage of fuel discounts through partner service stations. Stacking offers, such as supermarket-linked fuel discounts, can reduce the price per litre.
If you shop at Woolworths or Coles, remember to use fuel voucher offers available through Everyday Rewards and FlyBuys at participating service stations.
Save with gift cards and concession discounts
You may be able to reduce fuel costs by purchasing discounted gift cards through eligible programs. Seniors Card holders can also access discounted fuel gift cards, which can be helpful for families supporting older relatives.
Reduce fuel use through smarter travel
Driving less is one of the most effective ways to save money on petrol.
Carpool with coworkers if possible, or share school and sports drop-offs with other parents. If your role allows it, working from home more often can significantly reduce fuel costs and wear and tear on your car. For short trips, consider walking, cycling or using public transport where practical.
Improve your car’s aerodynamics and weight
Extra weight and wind resistance increase fuel use.
Remove unnecessary items from your car to reduce weight. Take off roof racks when they’re not in use, as they increase wind resistance and reduce fuel efficiency.
Plan ahead for long trips
Fuel prices can vary significantly between regions.
Before travelling, check petrol prices in different towns and plan where to refuel so you’re not caught paying premium prices in higher-cost areas.
Cut other car-related expenses
Saving on petrol is only one part of reducing overall car costs.
Review your car insurance regularly and ask your insurer about discounts for low kilometres, garaging your car overnight or bundling policies. Wash, vacuum and detail your car at home instead of paying for professional services to save even more.
Reducing petrol and car expenses can free up money in your weekly budget, especially for families who drive often. A few small changes to how and when you drive, refuel and maintain your car can make a meaningful difference over time.
