Choosing Your Diesel Truck Engine

Diesel Gas Cap

When shopping for a new pickup truck, you may have noticed that the use of diesel engines is growing in popularity. Truck drivers in the Bloomington-Normal area have more options than ever. So how do you decide which is right for you? Below, we have provided a guide to some of the top diesel engines currently available. See which one is best suited to your driving needs.

Difference Between Diesel vs. Gas Engines

While both gasoline and diesel engines are internal combustion engines, how the combustion process happens is what sets the two apart.
  • With a gasoline engine, fuel and air are mixed together before being compressed by pistons and ignited by spark plugs.
  • With a diesel engine, the air is first compressed before the fuel is injected. The fuel ignites because it heats up as it is being compressed.

Diesel engines and gasoline engines both feature a four-stroke combustion cycle, however diesel engines do not use spark plugs like gasoline engines. Now that you know a little more about the difference between diesel vs. gas engines, let’s take a closer look at some of the top diesel engines on the market.

Why Choose Diesel?

Why are more and more manufacturers offering diesel engines in their lineups? Diesel engines:

  • Are easy to maintain
  • They deliver more power from fuel
  • Offer superior torque at lower RPMs

Now that diesel fuel is relatively close to gasoline fuel in price, the fuel economy savings that come with diesel mean it’s often the better choice for drivers who need pure hauling power.
