Reduce Your Fuel Bill
- Check PetrolSpy or GasBuddy for the cheapest stations near you — prices can vary 20c/L in the same suburb.
- Fill up on Tuesday or Wednesday — the price cycle usually bottoms out mid-week.
- Consider E10 fuel — roughly 5c/L cheaper and compatible with most vehicles made after 1986.
- Work from home even one extra day per week and save significantly on your weekly fuel bill.
- Combine trips — batch errands into fewer journeys. Short cold-start trips burn 20% more fuel per km.
