Reasons To Love Diesel Truck Engines

In the market, there are either diesel truck engines or petrol-powered ones. When buying, you can choose either petrol or diesel-powered engines. Sometimes deciding on the one to choose may be difficult because you will hear those owning petrol-powered engines praise their trucks equally to those owning diesel-powered engines.

In this guide, the focus will be on diesel trucks. After reading it, you can decide which truck to choose based on what you want your truck to do for you. Here are some of the reasons why you should love diesel truck engines

The Torque

Diesel trucks usually have a higher torque as compared to their petrol counterparts. The high torque is attributed to the high compression ratio. The compression ratio is between the cylinders’ minimum and maximum volume. In diesel trucks, the cylinders are larger due to longer strokes. The pistons move up and down at a larger interval volume in each cylinder. 

Torque is the measure of the force that makes an object rotate on an axis. The above-explained process enables diesel trucks to burn fuel to generate more torque transmitted to the driveshaft. Diesel trucks can tow heavy loads and economize fuel consumption.


Diesel trucks are fuel efficient because of the thicker density of diesel fuel, high compression ratio, and low rpm performance. The thicker density allows diesel trucks to produce more power by consuming less fuel. Diesel trucks are, therefore, efficient and economical when it comes to fuel consumption as compared to petrol trucks.

Long Life

Diesel engines are usually big, which is why they last longer. They have higher compression ratios and higher cylinder pressure. For this reason, they have large crankshafts and camshafts that need larger bearings with big sturdy rod bolts. 

The large crankshaft and camshafts offer increased clearance for better oil flow. Better oil flow in the engine enhances engine lubrication resulting in reduced engine wear. Better engine lubrication increases the lifespan of the engine.

The absence of a spark plug, the existence of a piston cooling jet, and the gear-driven design are some of the unique modifications that give diesel truck engines a long life span.

Gas Economy

Diesel trucks are the best when it comes to gas mileage. Gas economy is better in bigger and heavy-duty trucks. A truck with diesel engines gets 25-30% better fuel economy, making diesel pick-up trucks more cost-effective. 

The fuel economy is due to the fact diesel fuel is denser than petrol fuel. Therefore the rate at which it burns is relatively slower than petrol. For this reason, diesel trucks will consume less after running for a long time than petrol trucks. 


There are a lot of reasons to fall in love with diesel trucks. They are powerful and can endure any task. The feeling of driving a diesel truck is entirely different from petrol trucks due to the big nature of the engine. Diesel trucks are generally pocket friendly when it comes to servicing. You only need to stick to your routine service and replace worn-out parts.
