Checking the Chevy Suburban’s Gas Mileage

by Brian Ang | Last Updated July 31, 2023 | 7 min read

Gas mileage is a major concern for potential car buyers who want to avoid a vehicle that could become a long-term financial burden. Large sports utility vehicles like the 2023 Chevy Suburban often draw attention to their powerful engines, making gas consumption a critical aspect to consider.

This full-sized automobile from Chevrolet offers a notably powerful and energy-efficient machine to handle various road conditions. With engine options like the 5.3L V8 producing 355 horsepower and the 6.2L V8 with 420HP, along with the 3.0L turbo-diesel generating 277 horsepower and 460 pound-feet of force, the Suburban provides a balance of performance and fuel economy.

Chevy Suburban’s Gas Mileage Specifications

Compared to other top sports utility vehicles in the market, the Suburban demonstrates sensible gas consumption. Despite its impressive 8,300-pound towing capacity, which ranks at the top of the SUV segment, the Suburban manages to offer reasonable fuel efficiency during a full cruise on the road.

Vs. Jeep Wagoneer

When compared to the Jeep Wagoneer, which has a twin-turbo V6 engine, the Suburban holds its own with 13 mpg and 14 mpg, respectively, in city and highway driving. While the Chevy boasts a V8 engine, it only moderately manages power throughout the process.

Vs. Chrysler Pacifica

Meanwhile, another leading motor figure in the business goes way ahead of the Chevy with its 17 and 28 mpg average consumption in city and highway driving. The numbers sounded ahead, but the Chrysler Pacifica rode on a V6 with a nine-speed transmission in contrast to the Suburban’s ten gears.

Vs. Ford Expedition

The Ford Expedition, although offering 16 mpg, has a smaller engine displacement compared to the Suburban’s V8. This difference places the Chevy on par with the Expedition’s fuel efficiency despite its more powerful engine.

Factors Affecting Gas Mileage

To many drivers, the price of a vehicle says something about gas consumption. Most of the time, popular cars spearheaded by the best companies in the industry get branded as fuel guzzlers. However, understanding some vital factors determines if such assumptions actually turned out to be true.

Engine Displacement

The Chevy may accept the fact that it utilizes a considerable amount of fuel due to its V8 machine offerings but such an approach comes with a provision. An engine displacement propelled by a 5.3L and 6.2L platforms also institutes an overwhelming potency that is uncommon in other vehicles.

Higher displacements bring in an increased efficiency whatever road this kind of automobile drives through. That is specifically what the Suburban brings at any time. Extensive usage of energy introduces a smoother and more powerful ride.

Speed

In terms of pace, introducing an average hustle of around 350 horsepower based on its three machine packages gives the Chevy a logical intention of using extra gas. The car shoots 60 mph between seven to eight seconds.

Meantime, the turbo-diesel variation hits 60 within eight to nine seconds. Any doubting driver realizes that getting to a sizable acceleration turned out to be worthy of utilizing a substantial quantity of fuel on a 10-speed automatic transmission.

Force

A grip on uneven and challenging thoroughfares sets the tone for a safe driving experience. A base torque of 383 pound-feet gives the Suburban more than enough force to manage its way through difficult surfaces.

Compared to regular cars, the grip statistic establishes tremendous might to put a sense of balance on unparalleled grounds. Whether the road portrays a straight or slope form, the automobile stays on top of the situation, especially with a traction control system engaged.

Loading Capacity

Against the Ford Expedition Max, the tussle between two considerably big sports utility vehicles should turn out to be a toss-up but instead, the extensive room wins it for the Chevy. The GMC product ekes out about a 123-inch edge to the Max’s 121 in terms of seating legroom.

Moreover, the cargo spacing past the third row of the automobile earns the honors for the Suburban with 280 cubic feet of leeway on average. The best that the Expedition provides turns out to be around 229.

Driving Habits

Often, a car owner’s driving habits get taken for granted. People tend to put too much emphasis on the engine itself as the main precursor of an increased Chevy Suburban gas mileage. While the machinery under the hood essentially triggers a substantial fuel economy, it should not bear the entire brunt.

Stepping hard on the gas pedal of a V8 or even a turbo-diesel engine naturally initiates an upsurge in fuel. Although treading on the accelerator depends largely on the type of surface a vehicle maneuvers on, the initiating process gets attributed to the individual behind the wheel.

Car owners need to learn the significance of pressing the pedal lightly. They should also educate themselves about maintaining the pacing momentum of their units which allows the vehicle to use what’s left of the motion going forward. Equally vital, they must not step on the brakes abruptly since it sets the thrust back to zero.

Tips for Fuel-Efficient Driving

Unless owners follow a schedule for periodic maintenance, their Suburban units ultimately fail to endure and uphold the automobile’s longevity. Other than getting a trusted mechanic to repair the vehicle, replacing components based on the attained mileage or the stretch traveled needs to be complied with.

Change Engine Oil

For a Chevy to maintain its efficiency, the car needs to change its oil. Utilizing a dirty lubricant gradually damages the metal parts of the automobile, especially in the transmission platform. Engines need to refresh their systems with the correct lube.

In addition, drivers must consider changing their engine oil every 5,000 miles. Further, the suggested mileage in replacing the coolant, the differential, and the transmission oils should be within the 15,000 to 30,000-mile range.

Check the Sensors

Most of the time, car owners ignore checking the sensors of their units. Considering that almost all automobiles nowadays find their machinery connected to an Electronic Control Unit (ECU) which monitors the functional necessities of the entire mechanical frame.

Sensors checking the oxygen mix, the mass airflow, and the throttle position, among many others, contribute heavily to the functional efficiency of the car. These components send messages to the ECU which evaluates the processes to be done. Any miscalculations lead to discrepancies and eventual failure of a connected system.

Maintain Filters and Spark Plugs

Another aspect of the Chevy that owners also take for granted points to the air filter. Utility units need to replace this part at least once a year. A clogged one contributes highly to the inefficiency of an engine resulting in reduced power output and increased gas or diesel consumption.

On the other hand, changing the spark plugs at least once in twelve months maintains the proper mixture of air and fuel. Maintaining a high voltage gives the vehicle a strong spark during ignition, thus, providing good gas mileage.

Clean the Injector and Replace Old Tires

Owners must also see to it that the fuel injectors of their units should be cleaned periodically. Any dirt hampering the metered flow of fuel into the engine deprives the system of the correct quantity which efficiently propels the car.

Lastly, replacing old tires becomes essential in sustaining the proper gas mileage of the sports utility automobile. Any impediment while rolling on the road only surges the fuel consumption and reduces the acceleration power of the unit.

It’s All a Matter of Proper Handling

Figures incurred in the Chevy Suburban’s gas mileage reflect not merely the vehicle’s engine efficacy or inefficiency. To an extent, how the owner manages the car says a lot about the impact of maintenance and replacement processes being done over time.
