20 MPG combined isn’t going to win any awards, but for the 2018 Lincoln MKX with the 3.7L V6 and front-wheel drive, it’s an acceptable trade-off for the smooth, responsive power and luxurious driving experience this model offers. This isn’t a vehicle bought by hypermilers. This MKX configuration caters to buyers who prioritize a refined, comfortable ride and effortless acceleration over squeezing every last mile out of a gallon of gas. They appreciate the quiet cabin, the upscale interior appointments, and the confident presence of a Lincoln SUV, even if it means slightly higher fuel costs than some competitors.

City and highway performance

The EPA estimates of 17 MPG in the city and 25 MPG on the highway paint a clear picture of where the 2018 MKX 3.7L FWD performs best. That relatively low city MPG reflects the stop-and-go driving conditions where the engine works harder and spends more time idling. The 25 MPG highway rating showcases the benefit of the six-speed automatic transmission finding its optimal gear for efficient cruising. Owners who spend more time on the open road can expect to see figures closer to, or even slightly above, that highway number. Conversely, those primarily confined to urban environments might find themselves closer to the 17 MPG city estimate, or even slightly below, depending on driving habits and traffic congestion.

Annual fuel cost

The EPA estimates the annual fuel cost for this specific 2018 Lincoln MKX configuration at $2,200. This figure is based on driving 15,000 miles per year and using the national average fuel price at the time of the estimate. It’s important to realize that this is just an estimate. Your actual fuel expenses will fluctuate depending on how many miles you drive annually and the prevailing fuel prices in your area. Aggressive driving habits and prolonged idling can also significantly increase your real-world fuel consumption, pushing that annual cost higher. Keep that $2,200 figure in mind when budgeting for the overall cost of ownership.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy often deviates from the official numbers. Many 2018 MKX 3.7L FWD drivers report figures that are reasonably close to the EPA estimates, but driving style and environmental factors play a critical role. Gentle acceleration, consistent speeds, and well-maintained tires contribute to better fuel efficiency. Conversely, frequent hard acceleration, heavy braking, and neglecting proper tire inflation will negatively impact your MPG. Consider these factors when interpreting the EPA estimates and setting realistic expectations for your MKX’s fuel performance. Owners can find MKX MPG across all years to better see real-world trends.

How it compares

Compared to its competitors, the 2018 Lincoln MKX’s fuel economy is generally in line with other mid-size luxury SUVs powered by V6 engines. For example, the 2018 Acura MDX with its 3.5L V6 also achieves around 20 MPG combined, while the Lexus RX 350, another popular choice in this segment, boasts slightly better fuel economy at 23 MPG combined. A BMW X3 xDrive30i from the same year, with a turbocharged four-cylinder, offers substantially better efficiency at 25 MPG combined. Buyers choose the Lincoln for a quieter, more isolated driving experience and a distinctly American luxury aesthetic. They understand that those benefits might mean a slight fuel economy penalty compared to some of the more overtly sporty or efficiency-focused options.

Tips to maximize efficiency

Avoid aggressive acceleration and braking. The 3.7L V6 in the MKX is responsive, but heavy-footed driving significantly reduces fuel efficiency. Smooth, gradual acceleration and anticipating traffic flow to minimize braking will make a noticeable difference over time. Imagine you have a glass of water on the dashboard, and drive in a way that avoids spilling that water; this will result in improved fuel economy!

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly, ideally every week or before a long trip, and inflate them to the pressure specified on the tire placard located on the driver’s side doorjamb. This will improve safety, handling, and fuel economy.

Minimize idling. Excessive idling wastes fuel and emits unnecessary pollutants. If you anticipate being stopped for more than a brief moment, like waiting for someone or sitting in a long drive-thru line, turn off the engine. Restarting the engine consumes less fuel than letting it idle for extended periods, particularly with modern vehicles.

Use cruise control on the highway. Engaging cruise control on long highway drives helps maintain a consistent speed, preventing unnecessary acceleration and deceleration that can negatively impact fuel efficiency. This feature is especially beneficial on relatively flat roads with minimal traffic fluctuations, allowing the car’s computer to manage the throttle and optimize fuel consumption.

Keep your vehicle well-maintained. Regular maintenance, including oil changes, air filter replacements, and spark plug inspections, ensures that the engine is running at peak efficiency. A poorly maintained engine works harder, consuming more fuel and potentially leading to more costly repairs down the road. Follow the recommended maintenance schedule in your owner’s manual to keep your MKX operating at its best.
