The 2017 GMC Canyon 2WD with the 2.8L Duramax diesel engine should realistically get 25 MPG combined. While this isn’t groundbreaking efficiency, especially for a mid-size pickup, it’s a key selling point for buyers who need truck capability without the high fuel costs of a larger V6 or V8. These owners prioritize torque for towing and hauling, and often accept the Canyon’s fuel consumption as a reasonable trade-off for diesel performance in a smaller, more maneuverable package.

City and highway performance

The EPA estimates for the 2017 Canyon 2WD diesel are 22 MPG in the city and 30 MPG on the highway. The city figure reflects the inherent inefficiencies of stop-and-go driving, where the diesel engine spends more time idling and less time in its optimal efficiency range. However, the 30 MPG highway rating is where this truck excels. The diesel’s torque allows it to cruise comfortably at highway speeds without burning excessive fuel, making it a decent choice for longer commutes or road trips where fuel costs can quickly add up. These figures are estimates, and your actual MPG will vary based on driving style, load, and terrain.

Annual Fuel Cost

The EPA estimates the annual fuel cost for the 2017 GMC Canyon 2WD 2.8L diesel at $2,250. This figure assumes 15,000 miles of driving per year, with a mix of city and highway driving, and is based on the national average fuel price at the time of calculation. Diesel fuel prices tend to fluctuate more than gasoline, particularly based on seasonal demand. Those who drive more than 15,000 miles per year or do primarily city driving will likely exceed this estimate. Use this figure as a baseline to see how all Gmc fuel economy data compares to other vehicles in the lineup.

Real-world expectations

While EPA estimates provide a standardized benchmark, real-world MPG can vary considerably. Canyon owners who frequently tow or haul heavy loads will see a significant drop in fuel economy. The diesel’s advantage is that it maintains decent efficiency even under moderate loads, unlike gasoline engines that can suffer a drastic MPG decline when working hard. Aggressive driving habits, such as rapid acceleration and hard braking, will also negatively impact fuel economy.

Drivers who prioritize smooth acceleration, maintain consistent speeds, and anticipate traffic conditions can often meet or even exceed the EPA estimates. Don’t forget to consider ambient temperature, as cooler weather will typically result in lower fuel economy as well.

How it compares

Compared to its gasoline-powered counterparts, the 2017 Canyon diesel offers better fuel economy. The 2017 Canyon 2WD with the 2.5L gasoline four-cylinder achieves only 22 MPG combined, while the 3.6L V6 2WD model is rated at 21 MPG combined. Across the midsize truck segment, the Toyota Tacoma 2WD with its 2.7L four-cylinder offers 21 MPG combined. The Nissan Frontier 2WD with its 2.5L four-cylinder is rated at 19 MPG combined.

The Canyon’s diesel delivers superior fuel efficiency compared to these more conventional gasoline engines, but it may not be enough to offset the higher purchase price of the diesel engine and potentially higher maintenance costs. Reviewing CANYON MPG across all years can provide additional benchmarks. The decision depends on individual needs and priorities.

Tips to maximize efficiency

Regular maintenance is critical for optimizing fuel economy in any vehicle, but particularly for diesel engines. Ensure that the air filter is clean and the oil is changed according to the manufacturer’s recommendations. Clogged air filters and old oil can increase engine friction and reduce efficiency.

Diesel engines benefit from a smooth, consistent driving style. Avoid aggressive acceleration and hard braking. Anticipate traffic flow and maintain a steady speed whenever possible. This will help the engine operate within its most efficient range.

Tire pressure plays an important role in fuel economy. Ensure that your tires are inflated to the recommended pressure, which can be found on the sticker located on the driver’s side doorjamb or in the owner’s manual. Underinflated tires increase rolling resistance and reduce MPG.

Minimize unnecessary weight. Remove any items from the bed of the truck that you don’t need, as extra weight increases fuel consumption. The Canyon’s modest payload capacity means every extra pound counts, both in terms of performance and mileage.

When idling for extended periods, consider turning off the engine. Modern diesel engines are designed to be restarted easily, and idling consumes fuel without moving the vehicle. This is particularly relevant in stop-and-go traffic or when waiting for someone.
