2017 Ford Explorer Sport Gas Mileage – Real-World Efficiency
The 2017 Ford Explorer Sport offers a blend of twin-turbocharged power and family-sized utility, but its fuel consumption reflects its performance-oriented design. While the EPA rates it at 18 MPG combined, real-world results vary significantly based on maintenance, driving style, and terrain. This guide provides actionable steps to maximize your efficiency while maintaining the 3.5L EcoBoost’s signature punch.
You bought a Ford Explorer Sport because you wanted the 3.5L EcoBoost V6 engine. This powerplant delivers 365 horsepower, making it a blast to drive on the highway or when passing on two-lane roads. However, that power often comes at a cost when you pull up to the pump.
When you look at the 2017 ford explorer sport gas mileage, you are essentially looking at the trade-off between a heavy, all-wheel-drive SUV and high-performance turbocharging. Many owners find that their actual numbers dip below the advertised ratings during winter months or heavy city driving. We understand the frustration of seeing your range drop faster than expected.
In this guide, we will break down the technical factors influencing your fuel economy. You will learn how to troubleshoot common efficiency killers and which maintenance tasks actually save you money. Let’s dive into the specifics of keeping your Explorer Sport running efficiently without sacrificing the “Sport” in its name.
Understanding the 2017 Ford Explorer Sport Gas Mileage Standards
The EPA ratings for this specific trim are 16 MPG in the city and 22 MPG on the highway. This results in a combined average of 18 MPG. Because the Sport trim comes standard with Intelligent 4WD, it naturally consumes more fuel than the front-wheel-drive base models.
Real-world data from thousands of drivers suggests that the 22 MPG highway rating is achievable only under ideal conditions. If you drive at 75 MPH or higher, the aerodynamic drag on this large SUV increases exponentially. You will likely see your highway numbers drop to 19 or 20 MPG at higher speeds.
City driving is where the Sport trim struggles the most. The stop-and-go nature of urban traffic requires the twin turbos to spool up frequently to move the 4,900-pound vehicle. Every time those turbos kick in, the engine demands more fuel enrichment to keep combustion temperatures safe.
The Impact of the 3.5L EcoBoost Engine
The “EcoBoost” name implies a mix of economy and boosting, but in the Explorer Sport, the emphasis is heavily on the “Boost” side. This engine uses direct injection and two small turbochargers to provide instant torque. While efficient for its size, it is very sensitive to how you use the throttle.
If you have a “lead foot,” the engine stays in a high-boost state. This bypasses the fuel-saving benefits of the smaller displacement engine. To get closer to the factory mileage ratings, you must learn to manage the boost gauge and keep the engine in its most efficient RPM range.
Maintenance Tips to Improve Your 2017 ford explorer sport gas mileage
Keeping your vehicle in top mechanical shape is the most effective way to protect your wallet. Small issues that don’t trigger a Check Engine Light can still cause a 10% to 15% drop in efficiency. Regular inspections of your ignition and air intake systems are crucial for this platform.
Start by checking your spark plugs every 30,000 to 45,000 miles. Turbocharged engines are notoriously hard on spark plugs. When the gap widens due to wear, the spark becomes less efficient, leading to incomplete combustion and wasted fuel. Use high-quality iridium plugs for the best results.
Your air filter is the lungs of your engine. A clogged filter forces the turbos to work harder to pull in air, which increases pumping losses. Replace your air filter every 15,000 miles, or more often if you drive on dusty trails or in heavy smog. A clean filter ensures the Mass Air Flow (MAF) sensor sends accurate data to the computer.
Tire Pressure and Alignment
Under-inflated tires are one of the biggest silent killers of fuel economy. For every 1 PSI your tires are under the recommended pressure, you lose about 0.2% in gas mileage. Check your door jamb sticker for the correct PSI and use a high-quality digital gauge every two weeks.
Wheel alignment also plays a major role. If your wheels are “toed out” or “toed in,” your tires are essentially scrubbing against the pavement. This creates rolling resistance that the engine has to overcome. If you notice your Explorer pulling to one side, get an alignment immediately to save your tires and your fuel.
The Role of Synthetic Oil
The 3.5L EcoBoost relies on oil not just for lubrication, but for cooling the turbocharger bearings. Using a high-quality full synthetic 5W-30 oil reduces internal friction better than conventional blends. Lower friction means the engine turns more easily, which can marginally improve your overall MPG over thousands of miles.
Driving Habits for Better Fuel Efficiency
How you drive is the single largest variable in the 2017 ford explorer sport gas mileage equation. Because this SUV uses a 6-speed SelectShift automatic transmission, it is designed to upshift early to save fuel. However, aggressive throttle input overrides this programming.
Practice “linear acceleration” rather than stomping on the gas. Imagine there is an egg between your foot and the pedal. By gently increasing speed, you allow the transmission to find the highest gear possible. This keeps the engine at lower RPMs where it is most efficient.
Use cruise control on flat highways to maintain a steady speed. The computer can manage the throttle much more precisely than a human foot. However, turn off cruise control in very hilly terrain. Sometimes it’s better to let the vehicle lose a little speed uphill rather than forcing a downshift to maintain a precise MPH.
Managing the Sport Mode
The 2017 Explorer Sport features a “Sport Mode” on the shifter. This mode holds gears longer and sharpens throttle response. While it makes the SUV feel much faster, it is the enemy of fuel economy. Save Sport Mode for mountain passes or merging into fast traffic, and use “Drive” for your daily commute.
Also, pay attention to your Intelligent 4WD display if you have it enabled in the productivity screen. While the system is mostly front-biased, heavy acceleration engages the rear wheels. This adds mechanical drag. Smooth starts keep the vehicle primarily in front-wheel drive, saving energy.
The Impact of Off-Road Gear and External Accessories
Many Explorer Sport owners enjoy light off-roading or camping trips. Adding accessories can drastically change the aerodynamics of your vehicle. A roof-mounted cargo box or a set of crossbars creates wind turbulence. Even when empty, these can drop your highway mileage by 1 to 2 MPG.
If you aren’t using your roof rack, remove it. Similarly, carrying extra weight inside the cabin hurts your city mileage. An extra 100 pounds of gear in the trunk can reduce your efficiency by 1%. Clean out your cargo area and only carry what you need for that specific trip.
Tire Choice and Tread Patterns
Switching from factory all-season tires to aggressive All-Terrain (A/T) tires will impact your fuel economy. A/T tires have larger tread blocks and more space between them, which increases rolling resistance. They are also typically heavier than highway tires.
If you want better off-road grip without destroying your MPG, look for “Hybrid” tires or A/T tires with a continuous center rib. This design provides a smoother rolling surface for the highway while keeping the outer lugs for mud and dirt. Always check the weight of the tire before purchasing; heavier tires require more torque to spin.
Troubleshooting Common Fuel Economy Killers
If your 2017 ford explorer sport gas mileage suddenly plummets, you likely have a mechanical issue. One common culprit on the Ford EcoBoost engines is a failing PCV (Positive Crankcase Ventilation) valve. If this valve sticks, it can cause oil blow-by and reduce engine efficiency.
Another issue is carbon buildup on the intake valves. Because the 2017 model uses direct injection, fuel does not wash over the back of the valves to clean them. Over time, carbon deposits can restrict airflow. Using a specialized intake valve cleaner or having a professional “walnut blasting” service can restore lost power and MPG.
Check for dragging brake calipers. This is a common problem in “rust belt” states where road salt can cause brake hardware to seize. If a caliper doesn’t fully retract, it acts like a permanent anchor. After a long drive, safely feel (do not touch!) near each wheel. If one wheel feels significantly hotter than the others, you likely have a sticking brake.
Oxygen Sensors and Catalytic Converters
Your vehicle uses oxygen sensors to tell the computer how much fuel to spray. If these sensors get “lazy” due to age or soot, they may signal the computer to run rich (too much fuel). This won’t always trigger a light, but it will kill your mileage. Replacing upstream oxygen sensors at 100,000 miles is a smart preventative measure.
Frequently Asked Questions About 2017 Ford Explorer Sport Gas Mileage
Does premium fuel improve the gas mileage of the 2017 Ford Explorer Sport?
Yes, but the improvement is often marginal. The 3.5L EcoBoost is designed to run on 87 octane, but the computer can advance the timing with 91 or 93 octane. This provides more power and can slightly improve MPG under load, such as when towing or climbing hills. For flat daily commuting, the cost of premium usually outweighs the small fuel savings.
How much does towing affect the gas mileage?
Towing a trailer will significantly impact your efficiency. When pulling a 3,000-pound boat or camper, expect your 2017 ford explorer sport gas mileage to drop into the 10 to 12 MPG range. The increased weight and aerodynamic drag of the trailer require the turbos to stay constantly engaged.
Does the 2017 Explorer Sport have an “Eco” mode?
Unlike some newer Ford models, the 2017 Explorer Sport does not have a dedicated “Eco” button. To drive “Eco,” you must manually manage your throttle input and keep the transmission in “D.” Monitoring the Instant Fuel Economy gauge on your dashboard is the best way to train yourself for better habits.
What is the most common reason for a sudden drop in MPG?
Apart from cold weather (which requires winter-blend fuel and longer warm-ups), the most common reason is a dirty air filter or a failing spark plug. If the engine detects a slight misfire, it will dump more fuel into the cylinders to protect the engine, which ruins your efficiency.
Maximizing Your Explorer’s Potential
Monitoring your 2017 ford explorer sport gas mileage during long trips is a great way to understand your vehicle’s health. While this SUV is built for performance, it is entirely possible to hit that 22 MPG highway mark with the right approach. It all comes down to the balance of maintenance and mindfulness.
Start with the basics: check your tire pressure, replace your air filter, and keep your cargo load light. When you’re behind the wheel, treat the gas pedal with respect and let the 6-speed transmission do its job. These small changes don’t just save you money at the pump; they also reduce wear and tear on your engine and turbos.
Optimizing your 2017 ford explorer sport gas mileage is a balance of science and habit. By following the tips in this guide, you can enjoy the thrilling performance of the EcoBoost V6 without feeling the sting of excessive fuel costs.
