The Chevy Silverado Gas Mileage: What to Expect

The Chevy Silverado is a popular truck that draws attention due to its impressive performance, durability, and affordability. However, when it comes to gas mileage, not all models are created equal.

If you’re looking to buy a Chevy Silverado, you might be wondering what kind of gas mileage you can expect. In this article, we’ll take a closer look at the Chevy Silverado gas mileage and what factors can affect it.

Base Gas Mileage

The Chevy Silverado base model comes equipped with a 4.3-liter V6 engine that delivers 285 horsepower and 305 lb-ft of torque. This engine is paired with a six-speed automatic transmission that provides efficient power transfer.

In terms of fuel economy, the Silverado’s base engine has an EPA rating of 18 mpg in the city and 24 mpg on the highway. This makes it one of the most fuel-efficient trucks in its class.

EcoTec3 Engines

The EcoTec3 engines are a series of three engines available on the Chevy Silverado that offer improved fuel efficiency without sacrificing performance. These engines include a 5.3-liter V8, a 6.2-liter V8, and a 4.3-liter V6.

The 5.3-liter V8 is the most common engine in the Silverado lineup and delivers 355 horsepower and 383 lb-ft of torque. It has an EPA rating of 15 mpg in the city and 22 mpg on the highway.

The 6.2-liter V8 is the most powerful engine available on the Silverado, producing 420 horsepower and 460 lb-ft of torque. Unsurprisingly, its EPA rating is the lowest of the three EcoTec3 options at 14 mpg in the city and 20 mpg on the highway.

Finally, the 4.3-liter V6 EcoTec3 engine delivers the same power as the base model V6 engine but with an added boost in fuel efficiency. It has an EPA rating of 17 mpg in the city and 22 mpg on the highway.

Factors Influencing Gas Mileage

While the standard and EcoTec3 engines provide a general idea of the Chevy Silverado’s gas mileage, a number of factors can influence fuel economy. Some of these factors include:

– Driving habits: Speeding, accelerating quickly, and braking abruptly can all decrease fuel efficiency.
– Load weight: The more weight in the Silverado, the harder the engine has to work to move it, reducing gas mileage.
– Terrain: Driving uphill, off-road, or in extreme temperatures can all affect fuel economy.


Overall, the Chevy Silverado offers competitive gas mileage compared to other trucks in its class. The base V6 engine is the most fuel-efficient option, with the EcoTec3 engines providing added performance and efficiency.

To optimize your Silverado’s gas mileage, practice good driving habits, avoid unnecessary weight, and be mindful of the driving conditions. With these tips, you can enjoy the power and utility of the Chevy Silverado without breaking the bank at the gas pump.
