20 MPG combined isn’t going to win any awards, but for the 2017 Chevrolet Silverado C15 2WD fitted with the 4.3L V6, it’s a practical choice for buyers who need truck capability without the thirst of a larger V8. This is the workhorse Silverado, the one you see on job sites and in commercial fleets. These owners aren’t prioritizing fuel efficiency above all else; they need a reliable tool, and they accept the fuel costs. They’re likely cross-shopping price and utility with other similar trucks, and the V6 Silverado offers good value in its segment.

City and highway performance

The EPA estimates for the 2017 Silverado C15 2WD with the 4.3L V6 are 18 MPG in the city and 24 MPG on the highway. The six-speed automatic transmission helps make the most of the V6’s power and contributes to decent highway fuel economy when unloaded. City fuel economy will suffer, particularly when hauling materials or equipment. The 4.3L V6 is a proven engine, known for its durability, but it has to work hard to move a full-size truck. Expect to see that reflected in your MPG, especially if your driving is biased towards urban stop-and-go conditions.

Annual fuel cost

The EPA estimates that the 2017 Chevrolet Silverado C15 2WD 4.3L V6 will cost $2,200 per year in fuel. This is based on driving 15,000 miles per year and national average fuel prices when the EPA performed its testing. Your actual fuel costs may vary depending on your driving habits, local fuel prices, and how often you are towing or hauling cargo. Consider this figure a reasonable benchmark, but anticipate potential fluctuations based on your specific circumstances.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world fuel economy for the 2017 Silverado C15 2WD 4.3L V6 will vary. If you frequently tow trailers or carry heavy loads, expect your fuel economy to drop below the EPA estimates. If you primarily use the truck for light-duty tasks and prioritize efficient driving habits, you may be able to achieve numbers closer to, or even slightly above, the official figures. Factors such as tire pressure, vehicle maintenance, and weather conditions can all influence your actual fuel consumption. Keep an eye on the dashboard display or track your fill-ups to get a clear picture of what to expect day-to-day.

How it compares

Compared to rivals, the 2017 Silverado’s V6 fuel economy is competitive. The Ford F-150, when equipped with its 3.5L V6, offered figures in the same ballpark, around 18 MPG city and 25 MPG highway for similar 2WD configurations. Ram’s 1500 with the 3.6L V6 posted nearly identical numbers. Upgrading to the smallest V8 available in the Silverado, the 5.3L will reduce fuel economy by 1-2 MPGs, leading to a significant cost gap over time. These differences, while seemingly small, can add up over the truck’s lifespan. When considering your purchase, explore all Chevrolet fuel economy data to make the right decision.

Tips to maximize efficiency

Gentle acceleration and anticipating traffic flow will significantly improve your mileage. Avoiding hard braking and aggressive starts conserves fuel, especially around town. The six-speed automatic is programmed to upshift early, so let it do its work. Keep your Silverado properly maintained. Regular oil changes, tire rotations, and filter replacements are essential for optimal engine performance and reduced friction. A well-maintained engine runs more efficiently.

Ensure your tires are inflated to the recommended pressure. Underinflated tires increase rolling resistance, which negatively impacts fuel economy. Check your tire pressure regularly, paying particular attention to the sticker on the driver’s side door jamb rather than the maximum pressure listed on the tire sidewall itself.

Reduce unnecessary weight in the bed of your Silverado. Hauling around extra tools, equipment, or other items adds to the vehicle’s overall weight, forcing the engine to work harder and consume more fuel. Clean out the bed regularly.

Minimize idling. Idling burns fuel without getting you anywhere and has little to no benefit for modern engines. If you’re stopped for more than a minute, turn off the engine. Restarting consumes less fuel than prolonged idling. The 4.3L is durable, but starting and stopping will prematurely wear other components.

Plan your routes strategically. Avoid routes with heavy traffic congestion or stop-and-go conditions whenever possible. Opt for routes that allow for consistent speeds, which will optimize fuel economy. This is especially true on the highway, where consistent speeds give the overdrive transmission a chance to work.
