20 MPG combined isn’t going to set any records, but for a full-size, rear-wheel-drive pickup truck like the 2020 Chevrolet Silverado 1500, equipped with its surprisingly potent 2.7-liter turbocharged four-cylinder engine, it’s a practical choice for buyers who want functionality without completely abandoning fuel efficiency. This configuration isn’t for those who need to tow heavy loads daily. It’s for contractors hauling tools, weekend warriors transporting gear, or those who appreciate the space and versatility of a truck bed but don’t need V8 power.

City and highway performance

The EPA estimates this Silverado at 19 MPG in the city and 22 MPG on the highway. The city number is close to the combined figure, suggesting the engine’s responsiveness and the eight-speed automatic transmission do a reasonable job of managing stop-and-go traffic without excessively punishing fuel consumption. Highway performance is where the 2.7L turbo shines. Its broad torque curve allows for relaxed cruising, minimizing the need for frequent downshifts and maximizing fuel efficiency on longer trips. The truck’s aerodynamic profile, while not groundbreaking, helps maintain decent mileage at steady speeds.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2020 Chevrolet Silverado 2WD 2.7L at exactly $2,200. This figure is based on driving 15,000 miles per year, using a national average fuel price. Remember this is an estimate. If you drive significantly more than 15,000 miles annually, or if fuel prices in your area are higher than the national average, your actual fuel costs will be higher. And if you primarily drive short distances in heavy traffic, you may find your real-world MPG figures, and therefore your annual fuel expenses, differ from the EPA’s projection. The $2,200 figure is a useful benchmark, individual driving habits and location will ultimately determine your true cost of fueling this truck.

Real-world expectations

While the EPA estimates provide a standardized benchmark, real-world fuel economy can vary based on driving style, load, and terrain. If you drive conservatively, avoid excessive idling, and primarily drive on relatively flat roads, you can expect to see figures close to the EPA estimates. Hauling heavy loads or frequently towing will significantly reduce fuel economy. Aggressive acceleration and high speeds will also negatively impact your MPG. Owners who want fuel efficiency and actively monitor their driving habits will likely find it easier to achieve or even exceed the EPA’s combined 20 MPG rating.

How it compares

Compared to other full-size trucks, the 2020 Silverado 2WD 2.7L holds its own in fuel economy. A comparable Ford F-150 with its 2.7-liter EcoBoost V6 engine delivers similar fuel economy, around 20 MPG combined. The Ram 1500, with its eTorque mild-hybrid system on the V6, may slightly edge out the Silverado in some scenarios. The important thing is understanding the tradeoffs. Choosing a V8 engine in any of these trucks will provide more power and towing capacity, but it will almost certainly result in lower fuel economy, often dropping into the 16-18 MPG range. This Silverado configuration is great for buyers willing to trade some raw power for better fuel efficiency that aligns with how they typically use their truck. See SILVERADO MPG across all years.

Tips to maximize efficiency

The 2.7L Silverado responds well to gentle throttle inputs. Since this is a turbocharged engine, avoid “stomping” on the accelerator to keep from triggering the turbo to spool up aggressively and dump fuel. Instead, accelerate smoothly and gradually to maximize fuel efficiency.

The eight-speed automatic transmission is designed to keep the engine in its most efficient operating range. Avoid manually shifting unless necessary. Let the transmission do its job and it will contribute to optimal fuel economy.

Tire pressure is important in fuel efficiency. Regularly check and maintain the recommended tire pressure, as specified on the doorjamb sticker. Underinflated tires increase rolling resistance and reduce MPG. Properly inflated tires also improve handling and extend tire life.

Minimize idling time, especially during colder months. Modern engines don’t require extended warm-up periods. Simply start the engine and begin driving gently. Excessive idling wastes fuel and contributes to unnecessary emissions.

Plan your routes to avoid congested areas and stop-and-go traffic when possible. Consistent speeds on open roads are more fuel-efficient than repeatedly accelerating and braking in heavy traffic.
