Is Diesel Better for Off-Roading?


Off-roading is an activity that is rapidly growing in popularity! With this increased traction, questions about the use of diesel for off-roading, particularly the debate comparing diesel to gas vehicles, have become increasingly prominent.

Although diesel vehicles are more expensive and require more maintenance, they are superior for off-roading due to their power, torque, mile range, efficiency, longevity, carrying capacity, high weight, fuel economy, and safety features.

While those are the prime motivations why diesel is better for off-roading, there are a few other reasons why diesel is better. Let’s dig deeper into all of the reasons for this to get a complete picture and deeper understanding of diesel vehicles as well as their off-roading capabilities.

1. Power and Torque

Torque is the amount of power a car has when changing directions while off-roading. Torque is important for off-roading because it maintains the force even while turning. The slope or descent, as well as the uneven terrain, are accommodated. Normally, doing so would have a significant impact on the engine and cause the wheels to spin, but not with diesel.

When it comes to power, several aspects of power make using diesel advantageous. The thing about off-roading is that the trail is never smooth—it is always rough and varies in difficulty. In contrast to car racing, the goal is not to go as fast as possible. Off-roading doesn’t have fast speeds, typically around 10 miles per hour. Because of its lower-speed torque, a diesel engine is more powerful and efficient. They optimize their power at low speeds, which is a massive advantage when navigating rocks and other obstacles.

2. Durability, Efficiency and Longevity

Diesel is the way to go if you want a car that will last for a long time. While some people try to replace their car after 50,000 miles to save money on repairs, the trump card with diesel vehicles is that it must be driven 100,000 miles before it is truly broken in.

Because of the way their engine is constructed, it is more resistant to pressure, bumps, and bruises. Diesel vehicles are sturdy, tough, and dependable, which is always an advantage when off-roading.

3. Mile Range

Diesel vehicles, particularly diesel trucks, are well-known for their incredible mileage per gallon of fuel. This is especially useful when off-roading because it allows you to travel farther off the road before returning to fill the car’s tank.

While most cars get less than 20 mpg, a large, heavy diesel vehicle can get 25+ miles per gallon, and mid-size to small diesel vehicles can get more than 30 miles per gallon. That is both impressive and useful! It also saves money on gas in the long run.

4. Fuel Economy

Although diesel fuel is more difficult to obtain, it has a higher fuel economy. Diesel fuel is known by several different names. If it is off-road diesel, it is known as red-dyed diesel, red fuel, alternative fuel, off-highway diesel, or farm diesel since off-road diesel vehicles include tractors, construction machines, four-wheelers or ATVs, and so on.

On-road diesel may be referred to as clear diesel, truck diesel, green diesel, or automobile diesel. Diesel vehicles save money on fuel not only because of the distance range per gallon but also because of the fuel consumption rates.

In addition, when comparing diesel and gas engines at 20% power, the diesel engine used 35% less fuel than the gas engine. Diesel vehicles have exceptional fuel economy!

5. Carrying Capacity

When it comes to towing capacity, diesel trucks outperform gas trucks. This is due to their low torque and excellent fuel economy. The low torque allows for more efficient use of energy and power, even when towing.

The mileage per gallon achieved is better in general and when carrying heavy objects, allowing it to travel farther and last longer. Diesel vehicles also have an exhaust brake, which comes in handy when towing downhill. This addition to the brakes reduces the strain on them and prevents them from being ruined or burned out due to holding the massive weight steady while falling.

6. The Terrain

Diesel vehicles, particularly diesel trucks, are less suited to muddy terrain but excel in hilly and rocky terrain. They are less proficient in muddy conditions because they have extra weight on the truck’s front end.

The additional weight and the uneven weight increase the likelihood of vehicles becoming stuck with their wheels spinning in the sludge. While this depends on the environment, it is far more common for terrain to consist of hills and rocks, and this is where diesel vehicles excel.

7. Safety

Diesel fuel is extremely difficult to ignite, no matter how silly or irrelevant it may appear. Due to the amount of work and pressure on the engine, the risk of fuel overheating and catching fire increases exponentially when off-roading.

Because of the additional strain on the engine, the temperature can rise to the point where the driver notices smoke coming from the engine. It is always preferable to avoid fuel fires, and diesel is ideal for this.
