The 2022 GMC Canyon 2WD diesel’s 23 MPG combined rating is perfectly justifiable. It won’t win any fuel efficiency awards, but for buyers who need a truck that can occasionally tow more than a compact crossover, and want something more maneuverable than a full-size pickup, it makes sense. This Canyon configuration appeals to those who prioritize diesel torque and durability over outright fuel efficiency, or the latest in tech and refinement, and who don’t need four-wheel drive for their typical use.

City and highway performance

The EPA estimates for the 2022 GMC Canyon 2WD 2.8L Duramax diesel are 20 MPG in the city and 30 MPG on the highway. The 20 MPG city figure suffers in stop-and-go traffic, where the Canyon’s weight takes its toll, even in two-wheel drive. However, the 30 MPG highway rating is achievable on longer trips, especially when driven conservatively. Owners report that maintaining momentum is key to achieving the best possible fuel economy, and the diesel’s abundant low-end torque makes this easier than with a comparable gasoline engine.

Annual fuel cost

The EPA estimates the annual fuel cost for this Canyon at $2,400. This is based on driving 15,000 miles per year, using the EPA’s projected national average fuel price. If you drive significantly more or less than 15,000 miles annually, or if fuel prices in your area are considerably higher or lower than the national average, your actual fuel costs will vary. The EPA’s number provides a reasonable baseline for comparison shopping, and allows you to quickly evaluate running costs.

Real-world expectations

While EPA figures offer a standardized benchmark, real-world fuel economy often deviates based on individual driving habits and conditions. Canyon owners who routinely tow trailers or carry heavy loads will see a decrease in fuel efficiency. Aggressive driving, frequent short trips, and neglecting routine maintenance can negatively impact mileage. However, those who prioritize smooth acceleration, anticipate traffic flow, and adhere to recommended maintenance schedules are more likely to approach or even exceed the EPA estimates. Online forums dedicated to the Canyon often contain detailed discussions about fuel economy, providing valuable insights from other owners. You can also find all GMC fuel economy data on this site.

How it compares

The fuel economy of the 2022 GMC Canyon 2WD 2.8L diesel exists in a specific area. Comparing it to other mid-size trucks reveals its pros and cons. For example, the 2WD gasoline-powered Chevrolet Colorado, mechanically similar to the Canyon, achieves around 19 MPG combined. The Toyota Tacoma, while generally less fuel-efficient, can get around 20 MPG combined in its 2WD four-cylinder configuration. Neither of these trucks offers the diesel’s torque for towing. The Jeep Gladiator, offering a similar blend of utility and off-road capability, has a lower average fuel economy of around 22 mpg combined for the diesel trim, which is also considerably more expensive. The Ford Ranger, with its turbocharged four-cylinder, achieves around 23 mpg combined in 2WD guise. Comparing CANYON MPG across all years can also be helpful during the research and buying process.

Tips to maximize efficiency

Anticipate traffic flow and avoid abrupt acceleration and braking. The diesel engine delivers its peak torque at low RPMs, so there’s no need to aggressively rev the engine to maintain speed or accelerate. Smooth acceleration is key to maximizing fuel economy in city driving. Keeping a steady foot on the accelerator while cruising also helps improve mileage.

Maintain a regular maintenance schedule, paying particular attention to air filter cleanliness and tire pressure. Clogged air filters restrict airflow to the engine, reducing combustion efficiency. Underinflated tires increase rolling resistance, forcing the engine to work harder. Check your tire pressure regularly and ensure that tires are properly inflated per the sticker on the driver’s side door jamb.

Minimize unnecessary cargo. Extra weight increases the amount of energy required to accelerate and maintain speed. Remove any items from the bed or cabin that are not essential, especially heavy objects. Every pound counts when trying to squeeze out the best possible fuel economy.

When highway driving, consider using cruise control to maintain a consistent speed. This can help prevent unintentional acceleration and deceleration, which can waste fuel. and try to avoid unnecessary lane changes, as these often require brief bursts of acceleration.

Avoid extended idling. Modern diesel engines do not require long warm-up periods. If you anticipate being stopped for more than a minute or two, turn off the engine. Prolonged idling consumes fuel without contributing to forward motion.
