23 MPG combined is a reasonable figure for the 2016 Chevrolet Colorado 4WD equipped with the 2.8L Duramax diesel engine, but it’s important to understand *why* someone chooses this powertrain. This isn’t about hypermiling; it’s about capability and longevity in a mid-size package. Buyers opt for this diesel Colorado configuration because they need confident towing for smaller trailers or boats, and they appreciate the low-end torque that helps in off-road situations. Fuel economy is a secondary, though welcome, benefit, not the primary driving force behind the purchase.

City and highway performance

The EPA estimates of 20 MPG in the city and 28 MPG on the highway provide a helpful snapshot of the Colorado diesel’s economy, but those numbers don’t tell the whole story. The city MPG reflects the engine’s efficiency in stop-and-go traffic, using its torque to get the truck moving without excessive throttle input. The 28 MPG highway figure is attainable when cruising at a steady speed, unloaded, but will decrease noticeably when towing or carrying heavy cargo. The 6-speed automatic transmission also plays a key role, keeping the engine in its optimal efficiency range whenever possible. Driving style significantly impacts fuel consumption, with aggressive acceleration and high speeds dramatically reducing these figures.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 Chevrolet Colorado 4WD 2.8L diesel at exactly $2,400 per year. This calculation is based on driving 15,000 miles annually, using a national average fuel price. Individual fuel costs will vary based on local diesel prices and driving habits, but this estimate provides a useful benchmark. Buyers considering this version of the Colorado should factor in potential fluctuations in fuel prices, as diesel can sometimes be more expensive than gasoline depending on market conditions.

Real-world expectations

While the EPA ratings are a good starting point, real-world fuel economy for the 2016 Chevrolet Colorado 4WD 2.8L diesel varies considerably. Owners frequently report figures slightly below the EPA estimates, especially in mixed driving conditions or when regularly towing or hauling. Expect to see around 18-22 MPG in combined city and highway use with light to moderate loads. Those who do a lot of towing can see their fuel economy drop below 18 MPG. However, those who primarily use the Colorado for highway commuting may even surpass the 28 MPG rating, especially if they drive conservatively. Individual results will always vary depending on driving habits, terrain, and load.

How it compares

Compared to other mid-size trucks of the era, the 2016 Chevrolet Colorado diesel offers a distinct fuel economy advantage over gasoline-powered alternatives, particularly when towing. For example, a 2016 Toyota Tacoma 4WD with the V6 engine achieves around 19 MPG combined. A similarly equipped Nissan Frontier manages roughly 17 MPG combined. Even the gasoline V6 Colorado hovers around 19 MPG combined. The fuel economy difference is most noticeable when towing; the diesel can maintain acceptable MPG while working hard, whereas the gasoline options suffer significant drops. When browsing COLORADO MPG across all years, remember that the diesel represents a very specific buyer with very specific priorities.

Tips to maximize efficiency

Avoid aggressive acceleration and braking. The 2.8L Duramax produces plenty of torque at low RPMs, so accelerate gently and allow the engine to pull the truck forward without excessive throttle input. Anticipate traffic conditions and coast whenever possible to minimize fuel consumption.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended level found on the door jamb sticker.

Reduce unnecessary weight. Carrying excessive cargo in the bed or cab of the Colorado increases the load on the engine, which consumes more fuel. Remove any unnecessary items to lighten the load and improve fuel efficiency.

Service the vehicle on time, every time. Regular maintenance, including oil changes, air filter replacements, and fuel filter replacements, ensures the engine runs efficiently. Consult the owner’s manual for recommended service intervals and stick to them religiously. Don’t forget to keep an eye on diesel exhaust fluid (DEF) levels, as this is critical to the engine’s emissions control system.

Limit idling. Extended idling wastes fuel. If you’re going to be stopped for more than a minute or two, turn off the engine. Modern diesel engines are designed to start quickly and reliably, so there’s no need to let them run unnecessarily. Be aware that colder temperatures might necessitate a short idle to warm the engine.

Consider a tonneau cover. A tonneau cover can reduce aerodynamic drag and improve fuel economy at highway speeds by smoothing airflow over the bed. Although the effect is subtle, it can make a small but noticeable difference, especially on longer trips.
