The right fuel type depends less on the vehicle and more on how much you drive and where you can refuel or charge. The comparison below is qualitative — plug your own fuel prices and mileage into the ownership-cost calculator for actual numbers.
Petrol
- Best for: low to moderate running, city use, lower purchase price.
- Pros: cheaper to buy, smooth and quiet, widely available fuel and service.
- Cons: higher fuel cost per kilometre than CNG, diesel or electric.
Diesel
- Best for: high running, long highway trips, heavy loads.
- Pros: strong low-speed torque and good fuel efficiency.
- Cons: costlier to buy, can be costlier to maintain, and regulations on older diesel vehicles vary by city.
CNG
- Best for: high city running where CNG stations are easy to reach.
- Pros: low running cost per kilometre.
- Cons: reduced boot space in many models, fewer refuelling stations outside cities, slightly lower power.
Electric
- Best for: predictable daily running with home or workplace charging.
- Pros: very low running cost, quiet, minimal routine maintenance.
- Cons: higher purchase price, range planning on long trips, dependence on charging access, and battery-warranty terms to understand.
How to decide
- Estimate your yearly kilometres.
- Note local fuel or electricity prices and the mileage or efficiency of each option.
- Compare five-year total cost (purchase + fuel + maintenance + insurance − resale) in the ownership-cost calculator.
- Check that refuelling or charging is practical where you live and work.
As a rule of thumb, the more you drive, the more a lower running-cost fuel type pays back its higher purchase price.
