The 2021 Chevrolet Silverado 2WD with the 4.3L V6 gets 17 MPG combined, but its fuel efficiency isn’t its main selling point. This is a work truck made for buyers who value capability and a low upfront cost more than saving money at the pump. This typically includes small business owners, contractors, and fleet managers who need a reliable, no-frills truck for work. They accept the fuel economy because the Silverado 2WD 4.3L is a tool, not a fuel-sipping commuter.

City and highway performance

The EPA estimates the Silverado 2WD 4.3L V6 at 16 MPG in the city and 21 MPG on the highway. These numbers reflect the engine’s older design and the truck’s weight and aerodynamics. The six-speed automatic transmission is reliable, but it’s not as efficient as the eight- or ten-speed units found in newer trucks or higher Silverado trims. City driving, with its stop-and-go nature, is where the Silverado’s fuel economy suffers most. The highway figure is more respectable, but still lags behind more modern powertrain options.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Chevrolet Silverado 2WD 4.3L V6 is $2,600. This is based on driving 15,000 miles per year and using the national average fuel price at the time of the EPA’s testing. Your fuel costs will vary depending on driving habits, local fuel prices, and the type of driving (city vs. highway). The $2,600 figure is a benchmark for understanding the potential cost of ownership of this configuration.

Real-world expectations

EPA numbers offer a baseline, but real-world fuel economy can vary. If you frequently tow or haul heavy loads, expect your MPG to drop below the EPA estimates. Aggressive driving, excessive idling, and neglected maintenance can also hurt fuel efficiency. However, careful driving, proper tire inflation, and regular servicing can help you get numbers closer to, or even slightly above, the EPA’s figures. Your driving style affects your actual fuel costs.

How it compares

The 2021 Silverado 2WD 4.3L V6 isn’t a fuel economy leader among full-size trucks. The Ford F-150 with the 2.7L EcoBoost V6 gets a combined EPA rating of 22 MPG in similar configurations. Even the Ram 1500 with the eTorque 3.6L V6 manages around 20 MPG combined. The Silverado’s lower fuel economy is an acceptable trade-off for its lower initial price and proven reliability. If you are sensitive to fuel costs, consider all Chevrolet fuel economy data, including the Silverado’s more efficient engine options, or consider lighter-duty trucks.

Tips to maximize efficiency

Gentle acceleration and smooth braking are crucial for maximizing fuel economy, especially in city driving where the Silverado’s MPG is lowest. The 4.3L V6 responds well to a light foot, so avoid hard acceleration and try to anticipate traffic flow to minimize braking. Maintain a safe following distance to avoid sudden stops.

Regular maintenance is essential for keeping your Silverado running efficiently. Ensure that your tires are properly inflated, as underinflated tires create more rolling resistance and reduce fuel economy. Follow the recommended maintenance schedule for oil changes, air filter replacements, and spark plug replacements.

Avoid unnecessary idling. If you’re stopped for more than a minute or two, turn off the engine. Idling consumes fuel without moving the vehicle, reducing fuel economy, especially in a larger displacement engine like the 4.3L V6.

When hauling cargo, distribute the weight evenly in the bed to maintain balance and reduce strain on the engine. Uneven weight distribution can affect handling and fuel economy. Also, consider removing any unnecessary weight from the truck bed or cabin.
