Two Major Advantages of Diesel Engines as Compared With Gas-Powered Equipment

Diesel usage is most common among certain foreign-made brands of passenger cars and big heavy-duty pickups, in addition to heavy equipment and larger vehicles like buses and tractors. Commercial and passenger vehicles that run on diesel fuel are required to have a certain level of diesel exhaust fluid in the system.

Emissions Control

The use of products like BlueDEF is important for keeping emissions at a minimum. The U.S. government requires this substance in diesel exhaust systems for this purpose, and manufacturers must include equipment that disables vehicles when the product runs out. Alert systems let drivers know well ahead of time that they need to refill the container.

This situation poses some inconvenience for owners and managers of fleets. However, those men and women find the advantages of diesel engines to be well worth the nominal cost and required effort of managing and dispensing diesel exhaust fluid.

Engine Durability

A main advantage of a diesel engine is its durability, meaning that it generally lasts substantially longer than gas-powered machinery. There also are no spark plugs to be replaced after a certain level of wear and tear.

That's a reason that some of the luxury car brands have a reputation for running more than 500,000 miles before a major breakdown occurs. It's also a reason why large commercial vehicles have these engines. Semi-trucks and other large equipment, including dump trucks, farm tractors and delivery trucks, are expected to easily travel upward of half a million miles. Drivers of those vehicles must use exhaust fluid products from a company such as PEAKHD.

Fuel Economy

Vehicles running on diesel get better fuel economy, all other things being relatively equal. This is another significant advantage for owners of automotive equipment that must travel a substantial number of miles on a regular basis. This could be over-the-road trucking in which drivers travel all over the country, or regional delivery work. Municipal buses don't travel very far, but the engines still rack up an impressive number of miles.

However, diesel fuel tends to cost more at the pump than gasoline does, and its price also tends to fluctuate more. The fuel has many other uses, such as for heating oil in furnaces and to power generators. That can cause prices to spike when demand is high. The only difference is that the kind intended for road vehicles is dyed red, indicating that it is subject to relevant taxes at the pump. Owners of diesel vehicles say they still come out ahead because of the better fuel economy, even when the price of diesel at the pump has increased temporarily.
