Diesel Truck Myths Busted: What You Really Need to Know

Posted on November 18, 2025

Diesel trucks have come a long way over the past two decades, yet many outdated myths still linger. Some drivers assume diesel engines are noisy, hard to maintain, or only suited for commercial use. But with the arrival of the 2026 Ram 2500 and Ram 3500 Heavy Duty trucks, it’s time to revisit the facts—especially for Canadian buyers who demand performance, durability, and comfort in equal measure.

 

If you’re shopping for a powerful pickup that can handle real work without compromise, here’s what you really need to know about diesel—myth by myth.

Myth 1: Diesel Trucks Are Loud and Uncomfortable

This one might have been true in the early 2000s, but not anymore.

 

The 2026 Ram Heavy Duty diesel lineup is surprisingly quiet and refined thanks to improvements in engine design and interior engineering. With Active Noise Cancellation technology, upgraded sound insulation, and vibration-dampening materials, the ride feels smooth and quiet—even at highway speeds or under load.

 

Upper trims like the Limited Longhorn and Limited offer interior features that rival luxury SUVs, including real wood and leather finishes, 12.3-inch Uconnect infotainment systems, and digital driver displays. Even work-focused trims like Tradesman are more refined than you’d expect from a heavy-duty diesel.

Myth 2: Diesel Engines Are Expensive to Maintain

It’s true that diesel engines require different maintenance than gas—such as DEF fluid and fuel filter changes—but they’re built for longevity and heavy-duty use. In fact, the 6.7L Cummins® Turbo Diesel I6 found in both the Ram 2500 and 3500 is engineered to run for hundreds of thousands of kilometres with proper care.

 

Diesel trucks often go longer between major services, and thanks to their lower-revving nature, parts experience less wear and tear under load. Even better, Canadian retail buyers of the 2026 Ram HD diesel models enjoy an exclusive 10-Year or 160,000-Kilometre Limited Powertrain Warranty, providing extra confidence and long-term value.

Myth 3: Diesel Is Just for Contractors and Commercial Fleets

Diesel’s not just for the job site anymore. More and more Canadian truck buyers are choosing diesel for personal use—especially if they tow recreational trailers, snowmobiles, boats, or campers.

 

The 2026 Ram 2500 diesel offers exceptional towing capability in a more everyday-friendly package, while the Ram 3500 delivers best-in-class diesel torque and a max gooseneck towing capacity of 36,610 lbs. Whether you're headed north for the weekend or helping a friend move, diesel gives you the muscle you need with none of the limitations.

Myth 4: Diesel Doesn’t Perform Well in Cold Weather

Diesel technology has evolved significantly to meet the challenges of Canadian winters.

 

The 2026 Ram Heavy Duty trucks are equipped with cold-start assist features, engine block heaters, heated fuel systems, and battery monitoring that allow diesel engines to start smoothly—even when temperatures dip below freezing. Ram’s Canadian models are designed with our climate in mind, and they’re tested to perform in some of the country’s harshest conditions.

 

Whether you’re working outdoors in Barrie or driving north in the dead of January, your diesel Ram will be ready to go.

Myth 5: Diesel Doesn’t Save You Money

Some drivers believe diesel costs more to operate—but that’s not always the case, especially if you tow or haul regularly.

 

Diesel engines are inherently more efficient under load than gas engines. They produce more torque with less throttle input and can travel further on a single tank when towing. Over time, especially for owners who use their truck for work or frequent trips, the fuel economy and reduced wear-and-tear can mean real savings.

 

Couple that with higher resale values for diesel trucks on the used market, and the economics of diesel ownership start to look very smart indeed.
