What Is the Best Diesel in a Pickup Truck?

Diesel as a fuel source has been around for decades, but its popularity in pickup trucks has grown significantly in recent years. Diesel engines provide increased torque, improved fuel economy, and a longer service life than their gasoline counterparts.

But with so many diesel engines on the market, it can be difficult for consumers to decide which one is the best.

The best diesel engine in a pickup truck depends on the individual’s needs and preferences. For those who prioritize power and torque, a heavy-duty diesel engine is the way to go.

These large engines provide higher levels of horsepower and torque than a comparable gas engine, allowing for heavier hauling capabilities and overall increased performance. Heavy-duty diesels are also great for towing applications, as they provide more torque at lower RPMs.

For those who prioritize fuel economy over power and torque, a light-duty diesel engine may be the better option. Light-duty diesels are smaller than their heavy-duty counterparts, but they still offer better fuel economy than gasoline engines. They also tend to be quieter and smoother running than gasoline engines, making them an ideal choice for those who don’t need maximum power or towing capability.

No matter which type of diesel engine you choose, there are plenty of options available from various manufacturers such as Cummins, Duramax, Powerstroke, and CAT. Each manufacturer offers its own unique benefits, so it’s important to consider all your options before deciding which one is best for you.


When it comes to finding the best diesel engine for a pickup truck, there is no single answer that fits all needs and preferences. Heavy duty diesels provide higher levels of power and torque for hauling heavier loads or for tow applications while lighter duty diesels offer improved fuel economy without sacrificing too much in terms of power or performance. Ultimately it comes down to personal preference when selecting the best diesel engine for your pickup truck.
