How Many Miles Per Gallon Does a Chevy Silverado 1500 Get?

Don’t you hate it? Ask how many miles per gallon a Chevrolet Silverado 1500 gets, and the honest answer is mildly annoying:

It depends. Of course it does.

Engine. Two-wheel drive or four-wheel drive. Tire choice. Trim. Whether you spend most of your time cruising on the highway or towing a trailer shaped like a small apartment.

All of it matters.

For the 2026 Silverado 1500, the most efficient setup is the available 3.0-liter Duramax turbo-diesel with two-wheel drive. It carries an EPA estimate of 23 mpg in the city and 28 mpg on the highway. Choose four-wheel drive, and the estimate drops slightly to 22 city and 26 highway.

That’s the headline. But it isn’t the whole answer.

Key Takeaways

Which Silverado gets the best fuel economy?

If fuel use is high on your priority list, the Duramax diesel deserves a serious look.

Along with that 28-mpg highway estimate, the engine produces 305 horsepower and 495 pound-feet of torque. It also supports up to 13,300 pounds of towing when the truck is properly configured. This isn’t an economy engine pretending to be a powerhouse. One that becomes helpless the moment you attach something to the hitch.

For a full-size pickup, that combination is impressive. And necessary to be honest.

Of course, diesel isn’t automatically the right choice for everyone. Diesel fuel prices are often substantially higher than gasoline prices. Maintenance needs aren’t identical. And if you mostly make short trips around town, the fuel savings may not outweigh the engine’s added purchase cost.

Ask yourself this simple question: how will you actually use the truck?

Not how you imagine using it during that one camping trip every third October. Your normal week.

What about the gasoline engines?

Of course, you have more options than diesel. The Silverado 1500 offers four engine choices for 2026: the TurboMax four-cylinder, a 5.3-liter V8, a 6.2-liter V8, and the 3.0-liter Duramax diesel. The exact EPA rating changes with the engine, drivetrain, trim, wheels, tires, and other equipment.

That means there is no single Chevy 1500 MPG figure that applies to every truck.

A rear-wheel-drive truck built for ordinary road use will generally return better mileage than a four-wheel-drive Trail Boss wearing aggressive all-terrain tires. No mystery there. More weight, more rolling resistance, more fuel.

Straight up physics. Always arriving with the bill.

The larger V8 engines are usually chosen for their power, towing character, and sound rather than their gas mileage. The TurboMax engine can make sense for drivers who want strong low-end torque without stepping up to a V8. The diesel is the efficiency leader, particularly for highway driving.

Why your real mileage never matches the advertised mileage?

But careful. EPA estimates are just that: estimates. EPA estimates are really only useful for comparing vehicles under standardized conditions.

They are not promises carved into the tailgate.

Your actual Silverado 1500 MPG will change because of:

• Towing or carrying heavy cargo
• Frequent short trips
• Cold weather
• Long periods of idling
• High speeds
• Low tire pressure
• Roof racks, lifts, and oversized tires
• Hard acceleration and braking

A lifted truck on 35-inch tires is not going to sip fuel like the stock truck shown on the window sticker. Asking it to would be like putting hiking boots on a marathon runner and blaming the runner.

Towing makes an especially large difference. The trailer adds weight and aerodynamic drag, and aerodynamic drag follows its own rules. It doesn’t care that your truck looked efficient on paper.

How should you compare Silverado fuel costs?

So what? Where do I start? Start with your annual mileage and the type of driving you do.

If you drive 15,000 miles per year, even a difference of two or three mpg can add up. But don’t stop there. Compare the complete cost. Fuel price. Purchase price. Maintenance. Capability. Resale value. The works.

When researching Chevrolet Silverado fuel economy, don’t choose an engine based only on the highest number in a chart. A truck that gets slightly better mileage but doesn’t meet your towing needs isn’t efficient. It’s simply the wrong truck.

Likewise, paying more for diesel may not make sense if you drive only a few thousand miles each year.

The best Chevy Silverado MPG choice is the one that fits the work you genuinely do. Your life, your work, your commute.
