Diesel Is the Better Choice for a Greener Earth and Poor man’s Wallet than Petrol On the planet Earth, there are over 5,000,000 cars running on the streets everyday, taking people from destination to destination. Of these cars, there are ones that run on petroleum, diesel, ethanol, electricity, and steam. In North America, there is a majority of petroleum or gasoline fueled cars, while Europe has a mixture of both petroleum cars and diesel cars; petroleum and diesel cars each have their advantages and disadvantages. At the moment, there are more petroleum cars than diesel cars in North
America. With the technology today, the “inherently dirty” (Lloyd) diesel powered automobiles are

Diesel fuel has a higher energy density than petroleum therefore it provides more energy per volume.
By getting more energy with the same volume ultimately provides a greater appeal to general consumers as fuel is sold by volume, not weight. Moreover the greater energy per volume allows for better fuel economy. This relates to another subject which is highlighted in the eyes of general consumers, the performance and efficiency of the two types of engines. There are conservative drivers, and then there are drivers who are in constant need for speed. Sadly for all the racer blooded drivers, diesel cars may not be what they want, due to pre-mixing of fuel and air the petrol engine operates at higher speed than diesel, but also limits the overall efficiency. Thus most performance cars and sport cars are generally made with petrol engines to accommodate the high speed. In addition, mechanically, diesel engines are heavier than petrol engines due to how the diesel engines are constructed. Diesel engines needs to be at a larger displacement than petrol engines and withstand the higher combustion pressures needed for ignition. Yet, with the heavier build it also allow car enthusiasts to acquire a tremendous amount of power and efficiency with the aid of a turbocharger. Alan Lloyd and Thomas Cackette of the
