Which are the best petrol or diesel cars?

 One of the perplexing decisions to make when buying a new car is to choose the car with the best engine suited to our needs, as each person's needs are different, so the actual decision to choose the car depends on many factors, such as the nature of the personal use of the car, the number of miles you will travel, as well as the cost of the engine and fuel, the driving experience of the engine efficiency and the speed of the car. During this report we will clarify the fundamental differences between diesel and petrol cars, so that you can choose the best car.

Which are the best petrol or diesel cars?

Diesel engines are more efficient than petrol engines:

One of the main reasons why some choose diesel cars is because of the engine's high efficiency. Diesel engines are about 40% more efficient than petrol engines when other factors are stable. A diesel car is less fuel consuming, travelling very large distances with the same amount of fuel when compared to its petrol-powered counterpart. 

According to CarsDirect reports, diesel cars travel 30% more petrol cars per gallon of fuel. This percentage is lower in trucks and SUVs, with diesel trucks traveling 20% more petrol trucks per gallon of fuel.

Thus, a diesel car is the best option if you use your car consistently and travel long distances on highways over 12 thousand miles per year, the more miles traveled, the more efficient the diesel engine is and the more you can save on fuel consumption. By contrast, gasoline cars are the best if all your commutes are within the city and only use your car at intervals for short distances.

Diesel cars are more expensive than petrol cars:

Unlike gasoline engines that rely on fuel burning (Gasoline) By generating an electric spark using ignition plugs, diesel engines depend on burning fuel Diesel without flaring plugs or the need to generate an electric spark. 

The fuel inside the combustion chamber is burned by air pressure in order to raise its temperature to very high to be burned by high temperature. Diesel engines have higher capabilities than gasoline engines so that they can compress and raise their temperature.

Diesel engines contain expensive components such as thick walls of cylinders and pistons so you can withstand high temperatures, as well as glow plugs used in cold areas to heat the engine to start compressing air and burning fuel, as these components increase the cost of manufacturing diesel engines which ultimately reflects on the total price of the car, according to the location "Cars Direct" diesel cars are more than $700 more expensive than petrol cars because petrol engines do not contain the exorbitant components found in diesel engines.

Diesel fuel is less expensive and more scarce than gasoline:

The thermal value of diesel fuel is about 45.5 MJ/kg, while the thermal value of gasoline is 45.8 MJ/kg. Thus the thermal value (i.e. total energy absolute as heat at full combustion of fuel by oxygen in standard conditions) Diesel fuel is slightly lower than gasoline, but it is even more dense, with about 15% more energy than petrol, and because diesel fuel is less expensive than gasoline in the refining process, reflects its price to the public, as it is sold at a cheaper price than petrol. (Some countries, such as the United Kingdom, have raised their price so as to reduce the use of diesel cars due to harmful sulphur dioxide emissions) despite having more energy.

Although diesel fuel is cheaper than petrol fuel, gasoline is more available and widespread, many petrol stations do not have diesel fuel. According to Business Insider, only about 50% of US petrol stations provide diesel fuel, so the best solution if you prefer to use diesel cars is to always make sure fuel is available by car and not wait to run out to fill it again.

Maintenance of diesel cars more expensive than petrol cars:

Diesel cars require fewer maintenance times than petrol cars, and because diesel cars do not use ignition plugs they will not need to be constantly prepared or repaired, however diesel cars require frequent oil changes along with constantly changing air filters, oil and fuel.

However, although diesel vehicles need little maintenance, not maintaining routine engine care can have catastrophic consequences, because diesel engine parts are more expensive than petrol engines. For example, a failure such as the collapse of the fuel injection system could result in significant losses, requiring multiple and costly repairs at the physical level. 

Therefore, if you see diesel cars as the right fit for your use, it is necessary to plan well to maintain the engine and provide it with inspection and periodic care, because the laxity of this leads to enormous costs when a fault or fault occurs.

Diesel cars are more polluting to the environment:

Diesel cars have always been known to be loud, but with technological development manufacturers have been able to take advantage of the technology's means to make the driving process quieter and smoother than the past. 

However, despite the superior technological development, manufacturers have been unable to eliminate pollution, and therefore many countries such as Paris, the United States of America and the United Kingdom are seeking to ban diesel cars completely by 2025.

Although emissions from petrol cars contain high carbon dioxide relative to diesel cars, emissions from diesel cars contain even more serious having high levels of nitrogen dioxide, for which exposure has been linked to abortion, congenital abnormalities and sudden infant death, Exposure also leads to lung cancer and heart disease as well as chest disease, allergies, asthma and infections The World Health Organization (WHO) notes that nitrogen dioxide causes more than 22 thousand deaths annually in Europe, It is estimated that 80% of nitrogen dioxide contamination is caused by car, truck and bus emissions.

Thus, after previous comparisons between petrol and diesel cars and their respective features and disadvantages, the vision should have become clear. Diesel cars are the ideal option for mobility and long-distance travel, It is characterized by low fuel cost compared to petrol cars, as well as its engines are more efficient and effective than petrol engines, Its drawbacks, in contrast, are high price, costly maintenance and the high proportion of the most environmentally polluting nitrogen dioxide emissions.
