Petrol, Diesel or Hybrid? A Guide to Choosing the Right Fuel Type
When buying a used car, choosing the right fuel type has a direct impact on your long-term ownership costs. Petrol, diesel and hybrid vehicles each have their own advantages and disadvantages. A CarExp used car report analyses the market value and maintenance costs of the vehicle you're considering based on its fuel type.
Petrol Cars
Advantages: Lower purchase price, widespread service network, well-suited to city driving. The simpler engine design generally means lower maintenance costs.
Disadvantages: Higher fuel consumption on longer journeys. Fuel efficiency can lag behind diesel and hybrid alternatives.
Best for: Short daily commutes and city use. An economical choice for drivers covering under 15,000 km per year.
Diesel Cars
Advantages: Low fuel consumption on motorways, high torque for towing and hauling. Cost-effective for high-mileage drivers.
Disadvantages: DPF clogging risk on short city trips. Maintenance costs can be higher than petrol. Emission restrictions in some cities are increasingly disadvantaging diesel vehicles.
Best for: Drivers covering over 25,000 km per year, particularly those doing regular long-distance journeys.
Hybrid Cars
Advantages: Low fuel consumption in city driving. Emissions significantly lower than petrol or diesel. Long-term fuel costs are advantageous.
Disadvantages: Higher purchase price. Hybrid battery replacement can be a significant expense. Verifying battery condition is critical when buying used.
Best for: Mixed-use drivers who want to minimise fuel costs.
Long-Term Cost Comparison
Over 100,000 km, fuel costs are lowest in hybrids, mid-range in diesel, and highest in petrol. However, the higher purchase price of hybrids and potential battery replacement costs can offset this advantage.
What to Check When Buying Used
For diesels, DPF and EGR condition are critical. For hybrids, battery capacity and service history are key. A CarExp report analyses the chronic issues specific to your chosen fuel type and provides a market value assessment.
