25 MPG combined is a reasonable figure for the 2016 GMC Canyon 2WD with the 2.8L Duramax diesel. This isn’t a full-size truck, but it’s also not a car-based crossover. It’s a mid-size pickup designed for buyers who need real truck capability, towing, payload, bed utility, but in a package that’s easier to maneuver and park than a Sierra 1500. For them, this fuel economy balances practicality with everyday usability.

City and highway performance

The EPA estimates for the Canyon 2WD diesel are 22 MPG in the city and 30 MPG on the highway. The city figure is understandable, given the engine’s need to work harder in stop-and-go traffic and the automatic transmission doing its job of keeping the engine in its peak powerband. The 30 MPG highway rating reflects the diesel’s ability to cruise efficiently at higher speeds, making it a good choice for longer commutes or road trips where fuel costs are a major concern.

Annual fuel cost

The EPA estimates that the annual fuel cost for this specific Canyon configuration is $2,250. This calculation is based on driving 15,000 miles per year and using the national average fuel price for diesel fuel at the time of calculation. Of course, your actual fuel costs will vary depending on your driving habits, the type of driving you do, and the price of diesel in your area.

Someone who tows frequently or drives mostly in heavy traffic will likely exceed this estimate. It’s a good starting point, but real-world results always vary.

Real-world expectations

While the EPA provides a standardized testing procedure, real-world fuel economy always varies. Factors like driving style, terrain, weather conditions, and cargo weight significantly impact the MPG you’ll see in your own driving. Expect lower MPG if you frequently haul heavy loads, tow trailers, or drive aggressively.

Conversely, if you prioritize smooth acceleration, maintain consistent speeds, and minimize idling, you might even be able to exceed the EPA estimates. Check out CANYON MPG across all years in our data to get a sense of owner-reported MPG.

How it compares

The 2016 Canyon’s fuel economy is worth considering against other mid-size trucks. A comparable gasoline-powered 2016 Toyota Tacoma 2WD with the 2.7L four-cylinder engine achieves only 21 MPG combined, 19 MPG city, and 25 MPG highway. A Chevrolet Colorado (the Canyon’s corporate twin) in a similar configuration has the same ratings. The diesel engine in the Canyon offers a clear edge in highway fuel economy.

However, the increase in initial cost of the diesel engine must always be factored in. It may not payoff in fuel savings alone during your period of ownership. Also consider that a 4WD Canyon with a gasoline engine might deliver combined MPG in the 18-20 MPG range and a larger Colorado/Canyon V6 will range from 17-20 MPG combined.

Tips to maximize efficiency

Regular maintenance is critical for optimal fuel economy. Ensure your Canyon’s tires are properly inflated, as underinflated tires increase rolling resistance and reduce MPG. Also, stick to the manufacturer’s recommended oil change schedule. Keep your engine running smoothly and efficiently.

Gentle acceleration and smooth braking can significantly improve your fuel economy. Avoid aggressive driving habits like rapid acceleration and hard braking, which waste fuel. Anticipate traffic flow and maintain a consistent speed whenever possible.

Minimize idling time. If you anticipate being stopped for more than a minute or two, turn off the engine. Excessive idling consumes fuel without covering any distance. Many Canyon/Colorado owners will let the engine idle for extended periods to keep the climate control on.

Consider removing any unnecessary weight from the truck’s bed or cabin. Extra weight reduces fuel economy. Hauling around tools or equipment you don’t need on a regular basis will reduce your MPG.

Finally, use cruise control on the highway to maintain a consistent speed and optimize fuel efficiency. Consistent speeds will help the diesel engine stay in its most efficient range, allowing you to get closer to the EPA’s 30 MPG highway rating.
