What Are the Best Diesel Truck Engines?

Overhead of Diesel Engine

In just a few short years, turbodiesel pickup trucks have become a popular choice on Waterford job sites. We’re also starting to see diesel engines available on medium-duty utility vehicles and carriers, and even making their way to smaller pickups and SUVs. There are two good reason for the shift: easy maintenance and more power from fuel. With its higher energy density, diesel requires less fuel than gasoline to generate equal power. That translates to 20% to 35% farther on a gallon of fuel*. The bottom line is that diesel engine fuel costs are lower than gasoline engines over the life of the vehicle.

With diesel engine competition starting to heat up, businesses and truck-buyers have more than a few diesel options to choose from. Read on to compare specs on five of the best diesel truck engines on the market right now, and then get in touch if you think diesel could be the next step for your business!
