A full tank in a mid-size car can cost north of $90 these days, and when you are filling up every week that adds up to a serious chunk of the household budget. I started FueVolt because I was tired of guessing which servo had the best price — but the tool is only half the story. How and when you drive matters just as much.
Here are ten strategies that can realistically save you hundreds of dollars a year without changing your car or your lifestyle dramatically. Several of them line up with the fuel-saving advice published by the Department of Infrastructure, Transport, Regional Development, Communications and the Arts.
1. Use a Price Comparison Service
The simplest saving is knowing where cheap fuel is before you fill up. Services like FueVolt retrieve government-reported price data from NSW, VIC, QLD and WA, showing you reported prices at stations near your location or along your route. The price difference between the cheapest and most expensive station in the same suburb can be 20 cents per litre or more — that is $12 on a 60-litre tank.
2. Buy at the Bottom of the Price Cycle
In Sydney, Melbourne and Brisbane, fuel prices follow predictable cycles where they spike sharply then gradually decline. Filling up just before the next spike — at the bottom of the cycle — can save 15 to 30 cents per litre compared to buying at the peak.
3. Fill Up Completely When Prices Are Low
When you find a bargain, fill the tank completely rather than putting in a set dollar amount. A full tank at the bottom of a price cycle maximises your savings and means you will not need to refuel again until prices have dropped.
4. Use E10 If Your Car Accepts It
E10 is typically three to five cents cheaper per litre than U91. While it has slightly lower energy content (about three per cent), the price saving more than compensates. Check your owner's manual to confirm compatibility.
5. Maintain Correct Tyre Pressure
Under-inflated tyres increase rolling resistance, forcing your engine to work harder. Checking tyre pressure monthly and keeping tyres at the manufacturer's recommended pressure can improve fuel economy by two to four per cent. That translates to roughly $50 to $100 per year for an average driver.
6. Remove Unnecessary Weight
Every 50 kilograms of extra weight in your car increases fuel consumption by about one to two per cent. Clear out heavy items you do not need — tools, sports equipment, boxes of stuff in the boot. Roof racks and cargo boxes increase aerodynamic drag significantly; remove them when not in use.
7. Drive Smoothly
Aggressive acceleration and hard braking waste fuel. Smooth, gradual acceleration uses the engine's most efficient operating range. Anticipate traffic flow and coast to red lights rather than braking hard at the last moment. Studies show that smooth driving can improve fuel economy by 15 to 20 per cent in urban conditions.
8. Use Cruise Control on Highways
Maintaining a constant speed on the highway is more fuel-efficient than constantly speeding up and slowing down. Cruise control eliminates the unconscious tendency to gradually increase speed. The Department of Infrastructure notes that at 110 km/h a car can use up to 25 per cent more fuel than at 90 km/h, so easing off the accelerator on a long trip adds up.
9. Combine Short Trips
A cold engine uses significantly more fuel than a warm one. Three separate short trips starting from cold use more fuel than one combined trip of the same total distance. Plan your errands to chain them together in one outing.
10. Service Your Car Regularly
A well-maintained engine runs more efficiently. Dirty air filters, old spark plugs, degraded engine oil and malfunctioning oxygen sensors all increase fuel consumption. Following your car's service schedule is an investment that pays for itself at the bowser.
Bonus: Loyalty Programs and Fuel Discounts
Supermarket fuel vouchers (Coles, Woolworths) typically save four cents per litre. Some credit cards offer fuel cashback. These small discounts add up across a year of regular fill-ups.
Combining several of these strategies can realistically save $500 to $1,000 per year for an average Australian household.
