Is petrol right for you?
Compare the exact car, engine and fuel grade, not just the fuel label.
Advantages
- Fast refuelling with established Australian fuel infrastructure; no home charger required.
- Many choices across sizes, ages and budgets, with broad familiarity among workshops.
- Can suit low annual kilometres or short-trip use when a more expensive alternative would not repay its price premium.
Disadvantages and trade-offs
- Fuel prices affect running costs; urban consumption can be higher than an equivalent efficient hybrid.
- Produces tailpipe emissions and needs engine servicing. Some models require higher-priced premium petrol.
- Turbochargers, direct injection and complex transmissions can carry significant repair costs; petrol does not automatically mean simple.
Check your fit
- ☐ Estimate annual distance, city/highway mix and actual fuel grade required by the manufacturer.
- ☐ Compare equivalent petrol and hybrid/EV models using total costs, insurance and expected ownership time.
- ☐ Assess towing and payload for the specific vehicle, plus your local fuel availability.
- ☐ For low-kilometre use, budget time-based servicing as well as kilometre-based intervals.
Petrol can be practical without charging access or high annual mileage. Its value depends on the specific vehicle and ownership period, not a universal fuel-saving claim.
Petrol buying & selling checks
Use with the main new/used purchase or selling checklist.
Buying new or used
- ☐ Check required octane rating and ethanol compatibility in the manual or fuel flap; do not assume E10 suits every car.
- ☐ Confirm service intervals and major scheduled work, such as timing-belt replacement where fitted.
- ☐ For used cars, arrange a cold-start inspection for misfire, unusual smoke, fluid leaks, overheating evidence and warning codes.
- ☐ Ask the mechanic to assess cooling, transmission, turbocharger where fitted and any relevant engine-specific issues.
- ☐ Test response, gear changes and restart behaviour. Confirm that any modifications are legal and accepted by your insurer.
- ☐ For new delivery, confirm fuel type and fitted engine/grade match the order and the fuel flap label.
Selling and handing over
- ☐ State the exact engine/grade, kilometres and fuel requirement. Avoid guessed consumption figures.
- ☐ Provide dated service invoices and receipts for significant repairs and scheduled component replacements.
- ☐ Disclose known oil use, cooling issues, warnings, modifications or other relevant faults accurately.
- ☐ Make cold-start and independent inspections practical for buyers.
- ☐ Provide keys, service records and manuals, agree the fuel level, then remove connected personal data after settlement.
A fresh oil change or cleared dashboard warning is not proof of good mechanical condition. Have a mechanic investigate symptoms and gaps in the history.
