What Are the Pros and Cons of Diesel?

What Are the Pros and Cons of Diesel?

In 2016, over 70% of cars in Ireland and Iceland were diesel powered.

Diesel is a popular choice for cars in Europe compared to the USA. There are many reasons for this. For example, governmental pressure on companies to produce cars which have low-emission rates.

But, if you are considering buying a diesel-powered vehicle, then you should read on. Here, you'll learn the pros and cons of diesel before you make a purchase.

Let's take a look so you can assess the risks for yourself.

Pros of Diesel

It's likely that the most common reason you'll hear as to why people chose to buy a diesel car is that it's fuel efficient.

In fact, it can get up to 35% more miles from a gallon than a gasoline-powered similar vehicle.

Diesel is now more expensive than the cheapest gasoline option. This is due to increased demand worldwide. However, you'll still be spending less over the course of the year.

Let's look at a few other diesel pros:

  • Less maintenance required on engines compared to gasoline-powered cars.
  • No need for ignition tune-ups
  • High torque compared to a gasoline-powered car making it better for towing
  • Better fuel economy
  • It's better for the environment helping countries to meet climate change targets

Clean diesel is often touted as the eco-friendly option for cars. (Of course, taking public transport is a lot better for the planet but it's not always possible.)

Diesel cars certainly emit less carbon into the atmosphere than a gasoline-powered vehicle. However, they do emit soot and carcinogens. Which leads us conveniently onto the cons of diesel...

Cons of Diesel

Due to worries that diesel cars are bad for our health, sales fell in the UK by 17% last year.

However, it's been pointed out that it's not clear-cut as to whether diesel is as damaging as many may believe.

It's true that such engines help to cut our carbon dioxide emissions. But, diesel cars do produce "particulates". These get deep into the lungs and can even cause heart attacks or strokes if there is too much exposure.

Thankfully, filters reduce this concern and release fewer particulates. But, when a diesel system is not working correctly, it can be very dangerous.

Other concerns about diesel cars include:

  • They're a greater expense - this is from higher fuel and mechanic prices
  • In the US, only around half of all gas stations have fuel pumps for diesel
  • They're noisier than gasoline-powered cars
  • Horsepower is decreased

In order to ensure your diesel engine isn't poisoning you, take it to a mechanic whenever you're concerned.

Pros and Cons of Diesel Help Drivers Decide

After reading both the pros and cons of diesel list, it's likely that you'll still be unsure as to which to side with.

That's largely because the fuel isn't perfect. Although it is better for the planet than gasoline, it's still a pollutant.

The best way to decide whether to buy a diesel car is to read more about them. So, check out the difference in efficiency between a diesel engine vs a gas engine.

    It’s awesome that this article explained that one of the benefits of diesel fuel is that it gets better fuel economy. It seems like this fuel would be good for heavy vehicles that do a lot of driving on a daily basis, such as semi-trucks. These trucks need to cover long distances, so they would need to use a fuel that can help them get far without having to fill up too often. https://www.stewartpwilsoninc.com/fuel-oil-delivery

    I like how you explained that you’ll be spending less on diesel over the year because diesel gets 35% more to miles to the gallon than gasoline. It’s good to know that diesel is able to cancel its con of being expensive by being more efficient. I have never owned a vehicle that uses diesel before but you have piqued my interest in buying one now.

    My father and I were talking on the phone a few days ago, simply catching up on one another’s lives and whatnot, and he mentioned to me that he was interested in becoming a trucker since his father had supplied him with an older vehicle before passing on, albeit one that needs some maintenance work done. We’re thankful that you brought up the fact that utilizing diesel fuel can allow a vehicle to drive with fewer mishaps arising due to it needing less maintenance. For now, we’ll be sure to research into what engine would be beneficial for the truck in my father’s possession. https://ashevilleengine.com/
