The 2019 Chevrolet Suburban K1500 4WD with the 6.2L V8 gets 16 MPG combined. It’s not a vehicle bought for fuel economy; it’s chosen for its unparalleled passenger and cargo capacity, its strong towing ability, and the undeniable presence it commands. Buyers aren’t oblivious to fuel costs, but they prioritize what this specific Suburban configuration offers: the capability to haul a large family, their gear, and a trailer, all while enjoying a smooth ride and ample power.

City and highway performance

The EPA estimates of 14 MPG in the city and 20 MPG on the highway reflect the realities of moving a vehicle this large and heavy. Stop-and-go traffic significantly impacts fuel efficiency, demanding more from the powerful 6.2L V8. However, the 10-speed automatic transmission is optimized for highway cruising, allowing the engine to settle into lower RPMs at higher speeds, contributing to the slightly better highway figure. The 20 MPG highway rating assumes consistent speeds and relatively flat terrain; mountainous regions or aggressive driving will obviously lower this number.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Chevrolet Suburban K1500 4WD 6.2L at $3,600. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices. This is a substantial sum, and potential buyers must factor this into the ownership equation. Understand that this is merely an estimate based on standardized testing and market averages. Your actual spending may be better or worse, depending on how and where you drive.

Real-world expectations

Don’t expect to consistently achieve the EPA’s numbers in real-world driving, especially if most of your miles are urban. Owners frequently report slightly lower figures, particularly in areas with heavy traffic congestion or hilly terrain. Hauling heavy loads or towing will also significantly impact fuel economy, pushing it considerably below the official ratings.

However, those who primarily use the Suburban for long highway trips might see results closer to the 20 MPG mark. Driving style, tire pressure, and vehicle maintenance all play a role in achieving the best possible fuel efficiency.

How it compares

Compared to other large SUVs with similar capabilities, the 2019 Suburban 6.2L’s fuel economy is generally within the expected range. The Ford Expedition Max with its 3.5L EcoBoost V6 achieves a slightly better 19 MPG combined in 4×4 configuration, though some may prefer the traditional feel of the Suburban’s V8. The Nissan Armada, another competitor in this segment, typically achieves around 15 MPG combined. Buyers often weigh these slight differences in fuel economy against other factors like seating capacity, cargo space, towing capacity, and overall vehicle features.

Tips to maximize efficiency

Avoid aggressive acceleration and braking. The powerful 6.2L V8 responds readily to throttle input, but using its full potential frequently will dramatically reduce fuel economy. Gentle acceleration and anticipating traffic flow can help conserve fuel. Let the 10-speed transmission do its job; it’s been carefully calibrated by GM engineers.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which forces the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate them to the recommended levels, found on the sticker inside the driver’s side doorjamb.

Reduce unnecessary weight. Carrying excessive cargo adds extra strain on the engine and reduces fuel economy. Remove any items you don’t need to lighten the load. This is especially important if you routinely haul extraneous items that are no longer needed.

Consider using cruise control on the highway. Maintaining a consistent speed helps to optimize fuel efficiency. Cruise control minimizes variations in throttle input, preventing unnecessary acceleration and deceleration that can waste fuel. It allows the engine to operate in its most efficient range for sustained periods.

Stay on top of routine maintenance. Regular oil changes, air filter replacements, and engine tune-ups can ensure your Suburban is running at peak efficiency. A well-maintained engine burns fuel more effectively, maximizing gas mileage over the long term. Don’t delay scheduled services.
