The 2018 GMC Yukon C1500 2WD, with the strong 6.2L V8, gets an EPA-estimated 17 MPG combined. Let’s be clear: nobody buys this Yukon for its excellent fuel consumption. This is a full-size, body-on-frame SUV with serious towing capability and a large interior volume. The target buyer needs to haul people or equipment, and they prioritize capability and space over saving gas. It is a trade-off they willingly accept.

City and highway performance

The EPA estimates the Yukon’s fuel economy at 14 MPG in the city and 23 MPG on the highway. The difference shows the impact of aerodynamics and consistent speed. In urban environments, stop-and-go traffic and frequent acceleration impact the 6.2L V8. However, once up to speed on the open road, the engine uses a more efficient operating range, aided by the 10-speed automatic transmission which helps keep the engine at a more economical RPM. Long highway journeys, which are common for Yukon owners pulling boats or campers, will achieve the best fuel economy.

Annual fuel cost

The EPA says the annual fuel cost for the 2018 GMC Yukon C1500 2WD 6.2L is about $3,400. This is based on driving 15,000 miles per year, using a national average fuel price as determined by the EPA. Your actual fuel costs will change depending on your driving habits, the type of gas you buy, where you live, and the number of miles you drive each year. Those towing regularly may see that annual cost rise very quickly.

Real-world expectations

The EPA provides a standardized test cycle, but real-world MPG changes. Drivers who frequently tow heavy loads or drive aggressively should expect to see fuel economy lower than the EPA estimates. On the other hand, those who drive conservatively and spend most of their time on the highway may see numbers slightly higher. Payload also hurts mileage in a vehicle like this. The 6.2L V8 is a performance engine in a large SUV and will use a lot of gas if pushed hard.

How it compares

Compared to other full-size SUVs in 2018, the Yukon 6.2L’s fuel economy is about average. A Ford Expedition with the 3.5L EcoBoost engine manages around 17 MPG combined in 2WD form. A Chevrolet Tahoe with the 5.3L V8 achieves 18 MPG combined in 2WD form. The Nissan Armada, known for its powerful V8, is similar at 15 MPG combined. These differences, while small, can add up over the course of a year. However, buyers considering the 6.2L Yukon are often more concerned with its superior horsepower and torque than a small improvement in MPG. They may wish to review all GMC fuel economy data.

Tips to maximize efficiency

Minimize aggressive acceleration. The 6.2L V8 is responsive, but every hard acceleration run costs gas. Gentle acceleration will save fuel and reduce wear on the tires and drivetrain. Drive with a light foot off the line.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which reduces fuel economy. Check the tire pressure regularly and inflate to the recommended level, typically found on a sticker inside the driver’s side doorjamb. A few PSI makes a difference.

Reduce unnecessary weight. Hauling extra weight around, whether inside the vehicle or in the cargo area, decreases fuel economy. Remove items you don’t need to carry regularly. This includes tools, sports equipment, and other unnecessary items.

Plan your routes efficiently. Avoiding stop-and-go traffic and congested areas can improve fuel economy. Use navigation apps to find the most efficient route, even if it’s slightly longer, and time your trips to avoid rush hour if possible. This is very important in the city.

Consider the YUKON MPG across all years. Keep your vehicle properly maintained. Regular maintenance, such as oil changes, air filter replacements, and tune-ups, ensures that the engine runs efficiently. A poorly maintained engine will consume more fuel. Keep up with all service intervals according to the manufacturer’s recommendations.
