Choosing Between Petrol & Diesel Vehicles

This discussion lasts from the beginning of time, and it is still impossible to know what the criteria for determining the winner are. That’s why we decided to introduce this guide and try to help future buyers to choose between petrol and diesel.

Petrol vs diesel – this is one of the favorite debating topics among car enthusiasts. It is also one of the most complicated questions for those who are trying to look at these issues realistically. Especially if you finally got rid of your old car through a cash for cars service, and now you are eagerly thinking about buying a new one.

Petrol vs Diesel

Natural gas for cooking, diesel for plowing, petrol for driving…

This has long been the favorite saying of passionate petrol-engine fans. But the real question is, how comparable are petrol to diesel engines?

Firstly, let’s establish some basic rules regarding the comparison of petrol and diesel engines. For example, we will be comparing engines of a similar generation, ie. age, power, sophistication.

You’ll often hear the advice that the best engines are older generation diesel-engines without turbochargers – they last forever and costly breakdowns occur very rarely. Unfortunately, vehicles with these engines usually have poor acceleration speed and are noisier than tractors.

So, is it fair to compare the turbo diesels and atmospheric petrol-engines? Not really.

Always account the following…

  • Purchase price of a new vehicle. Diesels are usually considerably more expensive, although the turbocharged petrol models are not cheap either.
  • Price fluctuations for second-hand car. The advantage is on the side of the diesel engine.
  • Possibility of costly failures. Sensitive nozzles, turbochargers, high pressure fuel pumps, DPF (diesel particulate filter)… Petrol vehicles win here by a large margin.
  • Sensitivity to fuel quality. Modern diesel engines are very sensitive to bad fuel.
  • Advanced diesels win here by an even larger margin.
  • The advantage is on the side of petrol.

New or second-hand car? If you are looking to buy a new car, there won’t be major differences in total costs (regular maintenance, spare parts, fuel …) and eventual costly failures in the first two years or up to 100 000 kilometers (mostly) will be covered by the warranty. Some manufacturers provide an even longer warranty period.

However, when it comes to second-hand cars, the situation becomes more complicated. Today almost no diesel engine is without a turbocharger, and it can easily break down after only 100,000 kilometers.

On the other hand, some diesel vehicles can withstand much higher mileage. Do not forget the nozzles, high pressure fuel pump and DPF. Of course, modern petrol engines are also very complicated, but costly failures with them are rarer.

Performance – many still believe that diesel vehicles do not have much to offer when it comes to sporty driving. Modern diesel engines are so powerful that the petrol engines without turbo charger of the same engine displacement are not even mild competition.

The ease of driving – diesels are in a solid advantage in this category, due to the high torque at low revs, although petrol vehicle with turbocharger nullifies the advantage.

Fuel consumption – it is clear who has the advantage when it comes to fuel consumption, diesel engines.

Maintenance costs – in general, diesels have higher maintenance costs that are “eating up” all the savings in fuel, but also modern petrol engines tend to be very expensive when it comes to maintenance.
