What’s the Deal with Diesel?

December 18th, 2017 by

When purchasing a new truck, you’re going to come to the age-old question of “gas or diesel?” There isn’t a right or wrong answer but while we all understand the meaning of a gas engine…What is the deal with diesel and what is the true difference of it in the truck?


History of Diesel

Diesel Engine

The diesel engine was first drafted in 1892 when Rudolf Diesel proposed an engine that was a constant temperature cycle, that would require a much higher compression than that of what’s needed for a
compression ignition. His idea was to end up compressing the air so tightly that the temperature of the air would exceed that of combustion. Think of it as a spark-less engine. While this cycle would be developed further throughout the years, it’s still the same main concept.

Trade in value of a Diesel Engine?

Diesel engines are going to be costing about $5,000 or more than same model with gas power. It’s also going to run you a little extra in maintenance. However, it is shown that diesel engines are going to saving you money in the long run because of their fuel economy.

All in All?

Diesel engines are going to make the most sense for you if you’re planning to tow a lot, put a lot of miles on your truck, or want to own it for many years. Another benefit is going to be the fact that diesel has a better resale value than that of their gas counterparts. If you’re someone that frequently trades trucks, this could be a huge benefit to you.


Diesel’s are going to be great for towing as well. Because of the way a diesel engine burns fuel, it’s going to provide more torque to the driveshaft. This meaning that with a diesel truck, it can out-tow any gas-powered vehicle while still delivering wonderful fuel economy.

Diesel in Cars?!

As for if a diesel car is worth it as opposed to a gas engine; it’s nearly the same as a truck version. It’s going to save you money in the long haul. Gas for a diesel engine is generally still a little cheaper than regular gas. As well as the fact that trucks get more power, so are diesel cars. The fuel is going to still provide more torque which means more towing power and more power off the line.

Diesel’s are also going to get you to go to the pump less often. Diesel’s are richer in energy. Compared to a electric vehicle, you’re going to find more places to refuel as opposed to having to find a recharging station.

What are the Pros and Cons of a Diesel?

As for the diesel engine, you can either take them ore leave them. It’s all your decision as the buyer. While provided with many facts above to the difference between gas and diesel engines, there’s still many other factors to take into account. Such as the advancement of technology, it’s going to provide more of a pay off to why you should get a diesel. Then there’s also the factors of other types of vehicles such as hybrid and electric, that you’ll have to take into account.

Pros Cons
  • Diesels are going to get great mileage, according to the U.S. Department of Energy they have a 30-35 percent better fuel economy than that of gasoline engines.
  • Because of the way diesel engines internally work, it doesn’t result in a flashy high-speed performance. The gas engine could be described as a “racehorse” while a diesel engine can be described as a “workhorse” because of it being stronger but slower.
  • Diesel fuel in the past has been significantly cheaper. However, presently, the prices are inching towards being a similar price as gas.
  • Just because maintenance on diesel engines isn’t as common, they still need regular maintenance in order to keep them running. They still need the normal changing of the oil and the air, oil, and fuel filters.
  • Diesel engines do not have spark plugs or distributors which means no ignition tune-ups.
  • If you end up neglecting the maintenance and the fuel injection breaks down, you’re going to have to get a diesel mechanic and pay them more money to repair engine because it’s more advanced than a gasoline system.
  • A diesel engine is built more ruggedly to withstand the higher compression. Which means that these vehicles are going to withstand some time. Models with diesel engines are seen to still be running after 900,000 miles.
  • The engine operates on high compression to ignite the fuel at very low RPMs which gives it it’s distinctive sound. Even with the changes in times, the engine is still going to be comparably loud to that of a gas engine because of its make.
