When it comes to buying a used car, one of the most critical decisions you’ll make is choosing the right fuel type – but with options ranging from traditional petrol and diesel to electric and hybrid vehicles, what is the best fuel type for cars?
Today’s blog is a guide to helping you understand the pros and cons of each of the different fuel types for cars, to make an informed choice that’s best for your particular driving needs as well as environmental considerations.
We’ll dive into the specifics of each car fuel type to see which might be the best fit for you, and whether the right fuel type for your car is petrol, diesel, electric or hybrid.
Petrol Cars
Petrol cars have long been the standard choice for many drivers, offering a balance of performance and cost.
Pros
- Cost: Petrol cars are generally cheaper to purchase compared to their diesel and hybrid counterparts. This lower initial cost makes them an attractive option for budget-conscious buyers.
- Performance: Petrol engines tend to offer better acceleration and smoother performance than diesels, making them ideal for city driving and short commutes.
- Availability: Petrol stations are widespread, making refuelling convenient no matter where you are.
- Maintenance: Petrol engines are simpler to build compared to diesel and hybrids, often leading to lower maintenance costs and fewer expensive repairs over the car’s lifetime.
Cons
- Fuel Economy: Petrol engines are less fuel-efficient than diesel engines, which means higher running costs if you drive long distances regularly. This can add up over time, particularly for high-mileage drivers.
- Environmental Impact: Petrol engines emit more CO2 compared to modern diesel engines, which can be a concern for eco-conscious buyers. While newer petrol engines are more efficient and cleaner, they still lag behind if you look purely at CO2 emissions.
- Complexity: Petrol engines have many more internal parts than an electric motor.
Diesel Cars
Diesel cars have historically been a popular choice for drivers covering long distances, thanks to their superior fuel economy. But high emissions now mean they are far less popular.
Pros
- Fuel Efficiency: Diesel engines are more fuel-efficient than petrol ones, especially on long journeys and for motorway driving. And better mileage can translate to significant cost savings over time.
- Torque: Diesel engines produce more torque, making them suitable for towing and carrying heavy loads. This makes diesel cars a popular choice for those who need a vehicle for work or recreational purposes that involve hauling.
- Longevity: Diesel engines tend to have a longer lifespan due to their robust construction and the fact that they operate at lower RPMs than petrol engines. This can result in a vehicle that remains reliable for many years. (One of our own cars is a Citroen diesel that has covered well over 500,000 miles!)
Cons
- Initial Cost: Diesel cars are generally more expensive to buy new than petrol cars. This higher initial cost can be a barrier for some buyers.
- Maintenance: Diesel engines can be more expensive to maintain and repair. Components like diesel particulate filters (DPFs) and turbochargers can add to the cost of ownership.
- Emissions: Although modern diesel engines are cleaner than older models, they still emit nitrogen oxides (NOx), which are harmful to air quality and health. This has led to increasing regulations and restrictions on diesel vehicles in some urban areas.
- Noise and Vibration: Diesel engines tend to be noisier and produce more vibration than petrol engines, which can affect the overall driving comfort.
Electric Cars
Electric vehicles (EVs) are considered by many to represent the future for cars, offering a cleaner and more sustainable alternative to traditional fuel types.
Pros
- Environmental Impact: Electric vehicles produce zero tailpipe emissions, making them the most environmentally friendly option. They significantly reduce the carbon footprint compared to petrol and diesel cars.
- Running Costs: Electricity is cheaper than petrol or diesel, and EVs have fewer moving parts, reducing maintenance costs. There are no oil changes, fewer brake replacements due to regenerative braking, and fewer components that can wear out.
- Performance: Electric cars offer instant torque, providing quick acceleration and a smooth, quiet driving experience. This can make driving an EV particularly enjoyable, especially in urban settings.
- Charging Convenience: For those with access to home charging, the convenience of starting each day with a full battery is significant.
Cons
- Range Anxiety: The range of electric cars on a single charge is often less than the range of a full tank of petrol or diesel, which can be a concern for long-distance drivers. While ranges are improving with new models, it remains a consideration for some buyers.
- Charging Infrastructure: Although rapidly improving, charging points are still not as easy to find as petrol stations, requiring more planning for longer trips. In areas with fewer charging stations, this can be a significant inconvenience.
- Initial Cost: Electric cars tend to be more expensive to purchase than petrol or diesel cars, although this is often offset by lower running costs and government incentives.
- Charging Time: Charging an electric car takes longer than refuelling a petrol or diesel car. While fast chargers can significantly reduce this time, it still requires planning, especially on longer journeys.

Hybrid Cars
Hybrid vehicles combine a petrol or diesel engine with an electric motor, offering a middle ground between traditional and electric vehicles. There are different types of hybrids, including mild hybrids, self-charging hybrids, and plug-in hybrids.
Mild Hybrids
Mild hybrids use a small electric motor to assist the petrol or diesel engine but cannot drive on electric power alone.
- Pros: Slightly better fuel economy than conventional petrol engines and lower emissions. The electric motor assists during acceleration, reducing the load on the engine and improving efficiency.
- Cons: The electric motor is not powerful enough to drive the car on its own, so the benefits are limited. They do not offer the same level of fuel savings as full hybrids or plug-in hybrids.
Self-Charging Hybrids
Self-charging hybrids (also known as full hybrids) can use electric power for short distances and recharge their batteries through regenerative braking.
- Pros: Better fuel efficiency and lower emissions compared to traditional petrol or diesel cars. They do not require plugging in as the battery charges through regenerative braking and the internal combustion engine.
- Cons: Limited electric-only range, which means they are less effective on long trips. They are more complex than mild hybrids, which can sometimes increase maintenance costs as they get older.
Plug-in Hybrids (PHEVs)
Plug-in hybrids have larger batteries that can be charged from an external power source, allowing them to drive on electric power alone for a limited range.
- Pros: Can be driven on electric power alone for short distances, reducing fuel consumption and emissions. They offer versatility as they can switch to petrol or diesel for longer trips, eliminating range anxiety.
- Cons: More expensive to buy than standard hybrids and require access to a charging point to maximize benefits. The added complexity of having both an electric motor and an internal combustion engine can increase maintenance costs.
Choosing the Best Fuel Type for Cars: Factors to Consider
When choosing the right fuel type for your used car, consider the following factors before you make a decision:
- Your Driving Habits: If you drive long distances regularly, a diesel or hybrid might be more cost-effective. For city driving and short commutes, petrol or electric cars could be better. Consider how often you drive, the distances you cover, and the type of roads you typically travel on.
- Environmental Impact: If reducing your carbon footprint is a priority, electric and hybrid vehicles are the best options. Consider the emissions associated with each fuel type and how they align with your environmental goals.
- Budget: Initial purchase price and ongoing running costs vary significantly between fuel types. Consider your budget for both buying the car and maintaining it. Calculate the total cost of ownership, including fuel, maintenance, insurance, and potential repairs.
- Availability of Infrastructure: Access to charging points for electric and plug-in hybrid cars can be a deciding factor, especially if you don’t have a home charger. Check the availability of charging stations in your area and along your usual routes.
- Resale Value: Consider how the fuel type will affect the car’s resale value. Diesel cars may have higher resale values, but this could change as more cities implement restrictions on diesel vehicles.
- Performance Needs: Think about your performance preferences and needs. If you enjoy quick acceleration and smooth driving, an electric car might be the best choice. For heavy loads and towing, a diesel vehicle could be more suitable.
- Government Policies: Stay informed about government policies and incentives related to fuel types. These can change and impact the financial viability of different options. Incentives for electric vehicles, such as tax breaks and grants, can make them more affordable.
What else to consider?
Insurance Costs
Different fuel types can also impact your insurance premiums. Electric cars, for example, might have higher insurance costs due to their higher purchase price and the specialised repair work required.
On the other hand, hybrids and diesel cars might have lower premiums due to their reliability and lower risk of theft. It’s worth getting insurance quotes for cars with the different fuel types you are considering.
