A Diesel Gasoline Comparison: Pros and Cons of Each

January 27, 2012

In a straight comparison between diesel and gasoline engines, there are a number of things which can be considered. Using gasoline in cars is a mainly American tradition, as there have always been a high percentage of diesel cars in Europe. If you're looking for a good reason not to purchase a car which runs on gasoline in the future, there are a number of cases in which diesel is much better, and more efficient.

  • Environmental Concerns: This is the primary reason why many people choose to use a diesel car, and in this debate it certainly has benefits in both using less fuel per mile, and also making less CO2, or carbon dioxide. But the diesel fuel is not completely pollution free, and in fact has been shown to produce carcinogens, soot and NOx, which can be just as harmful to the environment. It is a good idea, then, for designers to create filters and catalytic converters for diesel engines which help to reduce even this risk of pollution, making environmental concerns a good reason to purchase diesel.
  • Financial Considerations: There is very little difference between the two fuels in this heat. Diesel may be cheaper than gas half the time, but for the other half it is more expensive, so they are both about the same when it comes to the price of the fuel itself. However, diesel autos get better gas mileage, so there is a saving in that direction. Gasoline cars are cheaper as new purchases, as diesel cars can be around $700 more expensive.
  • Engine Performance: Surprisingly, the diesel fuel and engine combination can produce better engine performance, although this is lessened when the diesel use is bio-diesel, or other forms of enhanced fuel such as black diesel. If you intend to use the latter, then you will probably find that gasoline engines will outperform diesel cars.
  • Noise and Smoothness of Ride: This is another area where the gasoline car can easily out-do the diesel. While the latter no longer produces smoke under the bonnet, or horrible roaring noises, it is still louder than the gas car. You will also experience less of a smooth ride from your engine, which can make the drive a less pleasurable experience.

Diesel vs. Gasoline

Diesel is becoming an increasingly popular fuel source for vehicles in the United States, and there are many benefits to using this kind of fuel, not the least of which are improvements in the performance of your engine, and a reduced pollution problem. The benefits of gasoline include a smoother movement through the engine, meaning less noise and restricted movement, and the cheaper cost of cars which run on gasoline, although it is only a matter of time before cheaper diesel cars are produced.
