Take A Look At Diesel Engines

8/9/2020

As a Cummins Certified repair center, Bona Brothers Truck & Utilities has seen a fair share of diesel engines.  Let’s take a look at some of their common myths and how they are some of the hardest working vehicles on the road.

These work horse are typically found in larger commercial trucks (think over the road semi-tractors or construction company boom trucks) but are also found in pick up trucks and even passenger cars.

Let’s take a look at some common myths regarding diesel engines:

  1. Diesel exhaust is dirty. Images of black smoke billowing on the highway come to mind, and this used to be true many years ago. However, diesel engines in the United States have been required to use ultra-low sulfur diesel or USLD since 2006. This translates into a significantly lower carbon footprint as the exhaust is soot-free and is 33% more fuel efficient on average than gasoline engines.
  2. Diesels are loud and sluggish. Large commercial trucks by their nature will be louder and slower when compared to a typical car or pick-up truck. But, did you know that you can purchase an Audi, BMW, Jaguar, and many other luxury sedans and sports cars with diesel engines? A gasoline engine technically has more horsepower and top speeds, but the increased torque found in diesel engines gives you initial power that allows for quicker acceleration and can travel up hills easier. Add in that you no longer hear them from a mile away like you used to, diesel engines allow for surprisingly comfortable rides.
  3. Diesels have a bad resale value. Vehicles naturally depreciate with use and most people sell them well before the end of their useful life. Diesel engines tend to cost more on average but also have a considerably longer lifespan and have a higher resale value than their gas counterparts. Diesel engines require parts that are heavy and strong.

At Bona Brothers, we occasionally service cars and trucks that have over 300,000 lifetime miles. The quality of engineering makes diesel vehicles more expensive initially, but according to a study by the University of Michigan Transportation Research Institute, it was “found that based on fuel costs, resale value, and operating costs, diesel vehicles saved owners as much as $2,000 to $6,000 in Total Cost of Ownership (TCO) during a three to five year period when compared to similar gasoline vehicles.”

While there are many benefits to owning a vehicle with a diesel engine, one major concern for folks in the Minneapolis area is cold weather. Diesel engines do not have spark plugs and instead rely on temperature, which means they have a difficult time starting in our Minnesota winters. Fortunately, a simple fix is to add a “glow plug” or block heater that maintains a minimum temperature for easy starts.

If you are in the market for a new vehicle that is powerful, easy on fuel, and a relatively low cost of ownership with a high resale value, you may want to consider one with a diesel engine. Once you do, our team of ASE certified technicians and expert service advisors would be pleased to help keep your vehicle in peak condition for many years of use.
