Choosing between a gas and diesel engine is one of the most significant decisions a truck buyer will make. Jeremy at Redwater Dodge sees customers every day grappling with this choice. Whether you are eyeing a Rig Ready RAM or a workhorse for the job site, the engine under the hood dictates your long-term satisfaction and your wallet's health.

Based on expert insights from our team, including the Rig Ready specialists, we’ve broken down the essential factors to help you decide if a diesel engine is a necessity or an expensive luxury.

Is Diesel Necessary for Towing?

The short answer: It depends on your frequency and distance.

Many buyers feel they might tow something heavy in the future and default to diesel. However, we recommend a gas truck if you aren't planning on consistent, heavy-duty hauling. Gas engines are more than capable of handling modern loads, and they are generally more fuel-efficient for daily commuting and light tasks.

If your lifestyle involves hitting the road with a fifth-wheel every weekend or taking long-distance camping trips through varying elevations (like the trek up to Fort McMurray), the diesel engine becomes your best friend. The torque provided by a diesel powertrain makes long-haul towing significantly smoother and more stable.

The Financial "Break-Even" Point

One of the most common questions we hear is: “How often do I need to tow for a diesel to be financially worth it?”

If you only pull a boat or a horse trailer a couple of times a year, a Gas 2500 or 3500 is your most cost-effective option. Diesel engines require a higher upfront investment and come with higher fuel prices and maintenance costs. For the occasional tower, the fuel savings of a diesel engine won't offset the initial "diesel tax" paid at the time of purchase. However, for those putting on high mileage while under load, the efficiency and longevity of the diesel engine eventually pay for themselves.

The Reality of Diesel Ownership: Downsides to Consider

It’s not all high torque and whistling turbos. Diesel ownership comes with specific responsibilities. If your daily routine consists of short trips, dropping the kids at school or a five-minute commute to the office, a diesel engine may actually suffer. Diesels need to reach high operating temperatures to stay healthy.

Additionally, maintenance is a factor. You have to account for Diesel Exhaust Fluid (DEF) refills and generally higher service costs for oil changes and filter replacements. If you want a "turn-key and forget it" experience for occasional use, gas is the superior choice.

Resale Value: The Alberta Advantage

In regions like Alberta, the resale market heavily favors diesel. Because of our proximity to industrial hubs and the popularity of outdoor recreation (boating, camping, and off-roading), the demand for used diesel trucks remains incredibly high.

When you drive a diesel truck off the lot, you typically see less "immediate depreciation" compared to gas models. While you pay more upfront, you can expect to recover a significant portion of that investment when it’s time to trade in, provided the truck has been maintained properly.

Summary: Which Should You Choose?

Choose Gas if: You tow occasionally, take mostly short trips, and want lower upfront and maintenance costs.

Choose Diesel if: You tow heavy loads frequently, drive long distances, and want the highest possible resale value for your Rig Ready RAM.
