How to Save Money on Petrol in Australia: 12 Practical Tips for 2026
Discover practical ways to reduce your fuel costs in Australia, from smart driving habits to strategic refuelling techniques.
Australia’s fuel prices have been a constant concern for drivers, with the average cost per litre often exceeding $2.00 in many regions. Whether you’re commuting to work, running family errands, or planning a road trip, every cent saved on petrol adds up over time. The good news is that with the right strategies and a bit of planning, you can significantly reduce your fuel expenses without sacrificing convenience or comfort.
Understanding Your Fuel Consumption
Before diving into money-saving strategies, it’s essential to understand how much fuel your vehicle actually uses. Most Australian drivers have no idea how much fuel they’re consuming daily, which makes it nearly impossible to spot inefficiencies. The key is to track your fuel usage regularly and identify patterns that might be costing you extra.
Modern smartphones and apps can help monitor your fuel consumption, but for those who prefer a more hands-on approach, keeping a simple log of your fill-ups can be surprisingly effective. Note the odometer reading, the amount of fuel purchased, and the price per litre. This data will help you spot trends and make informed decisions about your driving habits.
Smart Driving Habits That Save Fuel
The most effective way to save on petrol is through smarter driving habits. Many Australians unknowingly waste fuel through common but avoidable driving practices. Here are some proven strategies:
Maintain a steady speed - Accelerate smoothly and avoid sudden stops and starts. The Australian Department of Infrastructure recommends maintaining speeds between 60-80 km/h on highways, as this range typically offers the best fuel efficiency for most vehicles.
Use cruise control - On long highway journeys, cruise control helps maintain consistent speeds and can improve fuel economy by up to 10%. This is particularly useful for those who drive regularly between cities.
Plan efficient routes - Use GPS navigation apps that consider traffic conditions to avoid congestion. Even a 10-minute delay in traffic can cost you an extra 0.5 litres of fuel, which adds up over time.
Remove excess weight - Every extra 100kg in your vehicle can reduce fuel efficiency by 1-2%. Keep your car clean and remove unnecessary items from your vehicle’s boot or passenger compartment.
Vehicle Maintenance for Maximum Efficiency
Regular vehicle maintenance isn’t just about keeping your car running smoothly—it’s also crucial for fuel economy. A well-maintained vehicle can be up to 15% more fuel-efficient than a neglected one.
Keep tires properly inflated - Underinflated tires can reduce fuel efficiency by up to 3%. Check your tire pressure monthly and inflate to the manufacturer’s recommended levels, which are typically found on the driver’s side door jamb or in your owner’s manual.
Change your oil regularly - Most manufacturers recommend oil changes every 10,000km or 12 months, whichever comes first. Fresh oil reduces friction in the engine, which directly impacts fuel consumption.
Replace air filters - A dirty air filter can reduce fuel efficiency by up to 10%. Replace your air filter every 12,000km or as recommended by your vehicle’s manufacturer.
Strategic Fuel Purchasing
Australia’s fuel prices vary significantly between locations, and savvy drivers know how to take advantage of this variation. The key is to be strategic about where and when you refuel.
Compare prices regularly - Fuel prices can vary by 20-30 cents per litre between different stations. Use apps like FuelCheck or PetrolStation to compare prices in your area. Many stations offer loyalty programs that can provide additional savings.
Refuel at the right time - Prices often fluctuate throughout the day. Many stations see price increases in the morning and decreases in the late afternoon. If possible, refuel during off-peak hours when prices may be lower.
Avoid filling up when the tank is nearly empty - This practice can actually reduce fuel efficiency because the fuel pump draws fuel from the bottom of the tank, where sediment and water may accumulate. Keep your tank at least half full for optimal performance.
The Power of Technology
Modern technology offers numerous tools to help drivers save money on fuel. One particularly useful device is a fuel efficiency monitor, which can provide real-time feedback on your driving habits and fuel consumption.
These devices provide immediate feedback on your driving behavior, helping you identify areas for improvement. They can track your fuel consumption, suggest optimal speeds, and even monitor your acceleration
