Exploring the Benefits: Why Are Diesels Better for Towing?

Sharing this content

Ever wondered why so many caravan enthusiasts swear by diesel for towing? Let’s dive into it…

It’s not just about raw power; there’s more to it. Diesel engines have a knack for making towing seem like a breeze, especially for those hefty caravans. But why is that?

Lower RPMs, higher torque – that’s the diesel mantra. More about this soon. Then there’s the fuel efficiency

Diesel engines are not only robust but also kind to your wallet on long hauls. Ah, the joy of fewer fuel stops!

Now, they’re not without their quirks. Modern diesels? They’ve evolved, and not all changes have been smooth sailing. But more on that in a moment.


Let’s embark on this journey, uncovering why diesel reigns supreme in the world of towing. And trust me, there’s a lot to uncover…

What concerns do you have about choosing the right towing vehicle? Maybe it’s about fuel efficiency, the cost, or just the sheer complexity of it all. We’d love to hear from you. Please drop a comment at the bottom of the page. Your insights could help fellow caravanning newcomers navigate these tricky waters.

The Technical Superiority of Diesel for Towing


Let’s start with the basics. Diesel engines, they’re a bit like the strong, silent type. They deliver power where it counts, especially at lower RPMs. That means pulling your caravan feels less like a chore and more like a smooth cruise.

Torque, that’s the magic word here. Diesel engines generate more of it and at lower speeds compared to petrol engines. This makes a huge difference when you’re pulling something hefty. It’s all about that steady pull, not just raw speed.

And then there’s fuel efficiency. You’re on a long journey, towing your home away from home. Diesel engines make those miles count, sipping fuel more efficiently than their petrol counterparts. Less frequent stops at the pump mean more time enjoying the scenic routes.

But it’s not just about saving pennies. Diesel’s fuel efficiency translates into less strain on the engine during those long hauls. It’s like giving your engine a well-deserved break while still doing the heavy lifting.

Diesel Engines: Durability and Longevity

Now, onto durability. Diesel engines, they’re built to last. Think of them as the marathon runners of engines. They keep going and going, often outlasting petrol engines.

This longevity isn’t just a happy accident. Diesel’s compression-based operation means fewer moving parts and less wear and tear. It’s like having a sturdy pair of boots that get better with age.

What about maintenance? Sure, diesel engines need love and care, but they reward you with reliable performance. Regular maintenance can see these engines hitting mileage that petrol engines can only dream of.

And let’s not forget, with longevity comes peace of mind. Knowing your engine won’t call it quits halfway through a journey is priceless, especially when you’ve got your caravan in tow.

Personal Insights: The Evolution of Diesel Technology

But let’s talk about the evolution of diesel engines. They’ve come a long way from the clunky, smoke-belching machines of the past. Today’s diesels? They’re more refined, but they’ve got their quirks.

Take the CDI common rail diesel injection, for example. It’s a leap forward in precision and efficiency, but it comes with a price. Those high-tech injectors? They’re not cheap to replace.

And there’s the issue of mixing electronics with diesel. It’s like trying to mix oil and water sometimes. Electronics bring efficiency, but they don’t always play nice with the dirty business of diesel combustion.

DPF filters, another modern addition, can be a bit of a headache. They’re there for a good reason, helping to keep emissions down, but they need attention to keep them working right.

Adblue and Its Quirks

Then there’s Adblue, a curious little addition to modern diesel engines. It’s there to reduce emissions, but it’s got its own story. Pigs urine? Well, not quite, but it’s an amusing thought.

When I first needed to top up, it was quite reasonable, but prices have crept up. Now, you’ll find it marked as a ‘great price’ even when it’s not so great. That’s inflation for you!

Using a fuel station is my go-to for Adblue, mainly because it’s less of a mess. Ever tried pouring it yourself? It can leave a stubborn white stain, a nightmare on a black driveway.

But despite these quirks, Adblue is part of the modern diesel experience. It’s a small price to pay for cleaner emissions and a little peace of mind.

Comparing Diesel to Alternatives: A Modern Perspective

Now, let’s compare diesel to its up-and-coming rival: electric vehicles. Electric, it’s the buzzword of the automotive world, but how does it fare in towing?

I met a chap in Dorset, had come all the way from Manchester with his twin-axle caravan. Behind an electric vehicle, no less! His tale was one of endurance.

Twelve hours on the road, frequent charging stops, and a fair bit of cash spent on coffee while waiting. Electric vehicles, they’ve got their perks, but for now, they’re not quite there for towing.

So, for the time being, diesel remains the king of the towing world. It’s got the power, the efficiency, and the durability that electric vehicles are still chasing.

Wrapping It Up: Our Diesel Towing Discoveries

So, we’ve taken a good look at why diesel engines are often the go-to choice for towing. It’s been quite the journey, uncovering the nuts and bolts of what makes diesel tick in the world of caravanning.

  • Torque and Efficiency: Diesel’s lower RPM torque and fuel efficiency make towing smoother and more economical.
  • Durability: These engines are long-distance runners, built to last longer than their petrol counterparts.
  • Modern Challenges: Advances like CDI and DPF have their benefits and drawbacks, and Adblue adds to the complexity.
  • Cost Considerations: While diesel engines might be more expensive initially, they pay off in the long run with fuel efficiency and longevity.
  • Electric vs Diesel: Electric vehicles are on the rise, but for now, diesel holds the crown in towing, especially for long journeys.


We spoke about AdBlue earlier, remember? It’s this clever concoction playing a key role in cleaning up our air, especially with diesel vehicles around. It’s all about tackling those pesky pollutants like Nitrous Oxide.

This AdBlue is not just any random mixture. It’s made of ultra-pure urea, which is synthetically produced from stuff you find in everyday products, like hair conditioner and skin creams. Mixed into demineralised water, it becomes a fuel for Selective Catalytic Reduction (SCR) systems. This is how we get one over on Nitrous Oxide emissions.

Here’s the kicker for us vehicle owners. By using the SCR system, our engines get tuned for peak fuel economy. It’s like squeezing every last bit of juice from the fuel, which means more miles per gallon. And you know what? The savings on fuel often offset the cost of AdBlue itself.

Another thing to note is the quality of AdBlue. To dodge costly catalyst replacement due to contamination, it’s essential to use AdBlue that meets the DIN70070 standard. That’s the kind of quality assurance we need for our vehicles.

And this particular AdBlue? It comes in a handy 10-litre bottle. Just right for keeping your diesel vehicle running clean and efficient.

  • Designed for use in passenger cars and vans
  • Reduced NOx pollution
  • Lower particulate emissions
  • Suitable for all vehicles fitted with SCR systems
