Diesel Engines – Pros and Cons

diesel engine

If you’re thinking about purchasing a new automobile in the near future, you may be considering one with a diesel engine versus a vehicle with a traditional gasoline powered engine.

There are several choices right now in regards to either diesel powered engines, gasoline engines or ones that operate on more of a hybrid system. There are also many things to consider before making your final choice and driving out of the dealership with your new car.


You have to decide what’s most important to you, both in the short term and in the long term. And once you’ve made those decisions, look over each type of car with those preferences in mind and make what you feel is the right choice for your particular situation.


There are many advantages to purchasing a car these days with a diesel engine, but there are some disadvantages you’ll want to consider as well. And these are all things to think about before spending your hard earned money on a car that will hopefully last you many years into the future.


Don’t make a purchase you may be saddled with for all those years without carefully considering all of the pros and cons of your decision. You might even want to think about talking things over with your spouse or significant other before making any final and long lasting decisions.

With all of that in mind, here are a few positives and negatives to think about before signing on the dotted line at the automobile dealership:


Pro #1 – Diesel Cars Get Great Mileage!

One of the biggest differences between diesel and gas engines is that vehicles with diesel powered engines typically get 25 to 30 miles to the gallon, sometimes more. This can save you a good deal of money at the gas pump in both the short and the long term.

If miles to the gallon is your chief concern, then a vehicle with a diesel powered engine could be the right choice for you. Just be sure to take all of the other considerations into account as well before making your final decision.

Pro # 2 – Diesel Fuel Is Very Efficient

If you care about the environment, and who doesn’t, vehicles with diesel engines are a great choice.

Diesel fuel is one of the most efficient and dense fuels available today and vehicles that have diesel engines are not only better for fuel economy, but also for the environment.

Pro # 3 – Diesel Engines Don’t Need Tune-Ups

Because cars with diesel engines don’t have spark plugs or distributors, this means that they never need tune-ups.

So even though they might cost a little bit more in the beginning, the fuel economy and the declining need for maintenance services will likely more than make up for it over time.

This is something to consider when you’re at the automobile dealership trying to decide which car is right for you and your family.

Pro #4 – Diesel Engines Usually Last Longer

Because of the way they’re built, diesel engines can usually last a lot longer before major repairs are needed.

So if longevity, durability and dependability are important to you, a car with a diesel engine is something you may want to consider.

Pro # 5 – Cars With Diesel Engines Have More Get Up And Go

Most cars with diesel engines are much faster from a standing start than are cars with traditional gasoline engines.

This is because a diesel engine provides far more torque to the driveshaft, meaning you can get up to your desired speed in a much shorter period of time.

Con # 1 – Diesel Fuel Is No Longer Cheaper Per Gallon Than Gasoline

While diesel fuel used to cost less at the pump than gasoline, that’s not usually the case these days. In many cases, diesel fuel even costs a bit more.

This is because the demand for diesel fuel has grown over the years and is now used for many different purposes, including for commercial vehicles, home generators and more.

Con # 2 – Diesel Engines Do Need To Be Maintained

While diesel engines don’t need regular tune-ups, as mentioned above, they do require a certain amount of maintenance. But how frequently should you have diesel engine maintenance? Well, that depends.

You’ll need to change the oil, the air filter and the oil filters on a regular basis, as well as the water separators that need to be emptied manually and regularly.

Con # 3 – Repairs Will Likely Be More Expensive

Particularly if you don’t keep up with the maintenance requirements of your diesel powered engine, repairs could be quite a bit more expensive than comparable repairs on a gasoline powered engine.

Diesel engines are more technologically advanced, so you’re going to want to keep up with the required maintenance. If you don’t, prepare to pay a significant price in terms of repair bills.
