Since the 1970s, diesel truck sales in the United States have skyrocketed. Despite their popularity, there are quite a few myths that exist that are not true and can sometimes prevent people from opting for a diesel truck over gasoline. Let’s take a look at some myths that you have likely heard but are not actually true!
Fuel Type Does Not Affect Exhaust After Treatment
It has actually been proven that high quality fuels can impact your exhaust, and can, in fact, reduce the amount of emissions. There are several components within the engine that help clean the exhaust when a good fuel is used; you should opt for one with high cetane level.
The Diesel Engine Has Not Evolved
This is completely untrue! Unlike many products available on the market, over time adjustments have been made. The same goes for a diesel engine; in fact, Congress passed the Phase 2 of the Corporate Average Fuel Economoy, diesel engine manufacturers were required to upgrade their engines to produce less emissions and also run more quietly.
Diesel Trucks Are Not Ideal for Long Journeys
It could be that less people own diesel powered vehicles who often make long commutes, but diesel engines are actually much more fuel efficient and higher performing than gasoline ones! Even at high altitudes, you can expect your diesel truck to run like a dream. Of course, you will need to ensure you are maintaining your diesel engine to ensure optimum performance.
Diesel Trucks Are Not Fuel Efficient
Diesel trucks are actually more fuel efficient than gasoline as they have a greater energy content per volumetric unit, and they have much higher thermal efficiencies. You can actually save 10-15% of fuel when driving the same journey compared to that of a gasoline vehicle.
Diesel Trucks Are Not Compatible in High Altitudes
You may be surprised to learn, but diesel trucks fare much better in higher altitudes than gasoline trucks do. As the air is thinner at higher altitudes, diesel trucks will draw more fuel, hence giving it more power.
You Must Idle Your Truck Prior To Use
This was once true, but there have been such advances in diesel engines that this is not required. In fact, the majority of diesel manufacturers do not recommend idling your diesel truck for more than three minutes as it can increase the strain on the engine – it can almost be compared to worse wear than driving on the highway.
Water Coolant Is Not Necessary
This is true if you want to wreck your diesel truck in no time at all! But, if you want to maintain your engine and keep your diesel truck for many years to come, it is crucial that you use sufficient water coolant so that your engine temperature is maintained to avoid overheating. When using turbocharger, you must note that your oil is being used for lubrication, which creates heat within the engine; to remedy this, be sure to use extra coolant.
Diesel Engines Cannot Be Tuned
For those who want additional torque and increased power, you will be relieved to know that diesel engines can, in fact, be tuned to suit your needs. It has also been noted that diesel engines can withstand more tuning than their gasoline counterparts.
Diesel Trucks Are Hard to Get Going in Colder Climates
Any engine can struggle to get started in colder climates, not just diesel engines! Your diesel truck can run perfectly in the winter if you ensure proper maintenance. You will want to ensure that the intake grid heater is working properly, your batteries are operating well and glow plugs are in tip-top condition. There is actually a handy feature that diesel trucks have that help them during colder times – block heaters! Speak to a diesel expert to learn more about how to use it if you are not aware of this part.
Diesel Trucks Are Expensive to Run
Due to pricier diesel rates, many people in turn assume that it makes them more expensive when it comes to maintenance and repair issues. While some maintenance issues can be pricey if they have been left too long, in general, services and general maintenance costs no more than that of a gasoline engine. Diesel trucks are also far more durable and robust, which makes less likely to have maintenance issues when cared for properly.
