Understanding the Base Stats: Gas Mileage for 2017 Ford Explorer Engines
The 2017 Ford Explorer came with three distinct engine options, each offering a different balance of power and efficiency. The 2.3L EcoBoost four-cylinder is generally the most fuel-efficient choice for those prioritizing daily savings.
If your vehicle has the standard 3.5L Ti-VCT V6, you can expect a middle-ground performance that balances reliability with decent highway numbers. This engine is a workhorse but lacks the sophisticated turbocharging found in the EcoBoost family.
For those driving the Sport or Platinum trims, the 3.5L EcoBoost V6 provides massive power but comes with a trade-off at the pump. This twin-turbocharged beast requires more fuel to maintain its high-performance output, especially under heavy acceleration.
EPA Ratings by Configuration
- 2.3L EcoBoost (FWD): 19 city / 27 highway / 22 combined MPGs.
- 2.3L EcoBoost (4WD): 18 city / 25 highway / 21 combined MPGs.
- 3.5L V6 (FWD): 17 city / 24 highway / 20 combined MPGs.
- 3.5L V6 (4WD): 16 city / 23 highway / 19 combined MPGs.
- 3.5L EcoBoost V6 (4WD): 16 city / 22 highway / 18 combined MPGs.
Engine Options and Their Impact on Fuel Economy
The powertrain configuration plays the most significant role in your overall fuel consumption. Front-wheel drive (FWD) models consistently outperform four-wheel drive (4WD) versions because they have less rotational mass to move.
The 2.3L EcoBoost uses gasoline direct injection and turbocharging to extract more energy from less fuel. This makes it the ideal choice for suburban families who rarely tow heavy trailers but want a responsive driving experience.
In contrast, the 3.5L EcoBoost V6 uses twin turbochargers to deliver V8-like torque. While fun to drive, the gas mileage for 2017 ford explorer models with this engine can drop significantly if you have a “heavy foot” or drive primarily in stop-and-go traffic.
The 6-Speed SelectShift Automatic
All 2017 Explorers use a 6-speed automatic transmission designed to optimize shift points for efficiency. If your transmission fluid is old or burnt, the torque converter may not lock up efficiently, leading to wasted energy and higher fuel consumption.
Always check your transmission fluid level and color during your routine oil changes. Clean, bright red fluid ensures the transmission shifts smoothly and keeps the engine in its most efficient RPM range.
Common Factors That Kill Your Ford Explorer’s MPGs
Even a perfectly tuned engine can suffer from poor efficiency if external factors are working against it. One of the most common culprits is tire pressure, which many owners overlook during seasonal temperature changes.
Under-inflated tires increase rolling resistance, forcing the engine to work harder to maintain speed. Check your driver-side door jamb for the recommended PSI and use a high-quality digital gauge to ensure accuracy.
Aerodynamics also play a massive role in how much fuel you burn at highway speeds. Carrying a roof-mounted cargo box or heavy off-road recovery gear creates drag, which can slash your highway efficiency by 10% or more.
Weight and Payload Considerations
The Explorer is a heavy vehicle, but adding extra weight inside the cabin further taxes the engine. Remove unnecessary tools, camping gear, or heavy equipment from the cargo area when you aren’t using them.
Every 100 pounds of extra weight can reduce your fuel economy by about 1%. For a vehicle that already weighs over 4,500 pounds, managing your payload is an easy way to see immediate gains at the pump.
DIY Maintenance Steps to Improve Gas Mileage for 2017 Ford Explorer
If you notice a sudden drop in your fuel economy, it is time to get under the hood. Start by inspecting your engine air filter, as a clogged filter restricts airflow and forces the engine to burn more fuel to compensate.
Replacing a dirty air filter is a five-minute job that requires no special tools on the 2017 Explorer. Simply unclip the airbox, swap the filter, and ensure the seal is tight to prevent “unmetered air” from entering the system.
Another critical component is the spark plugs, especially on EcoBoost engines which are known to be tough on plugs. Over time, the gap between the electrodes widens, leading to inefficient combustion and lost power.
Cleaning the Mass Airflow (MAF) Sensor
- Locate the MAF sensor on the intake tube near the air filter box.
- Disconnect the electrical connector and remove the sensor carefully.
- Spray the sensor wires with a dedicated MAF sensor cleaner (do not use brake cleaner).
- Allow it to air dry completely before reinstalling to avoid damaging the delicate electronics.
A clean MAF sensor provides the engine computer with accurate data about how much air is entering the engine. This allows the ECU to calculate the perfect air-fuel ratio, directly improving your gas mileage for 2017 ford explorer.
The Role of Driving Habits and Payload
How you drive is just as important as what you drive when it comes to fuel efficiency. Aggressive acceleration and hard braking are the fastest ways to ruin your average MPGs on any trip.
Try to use the cruise control feature on flat highways to maintain a steady speed. The 2017 Explorer’s computer is much better at managing throttle inputs than a human foot over long distances.
If you frequently drive in hilly terrain, avoid letting the transmission “hunt” for gears. Shifting into “S” or Sport mode can sometimes help on steep inclines by holding a gear longer, preventing constant downshifting that wastes fuel.
Idling and Fuel Waste
Modern engines do not need a long warm-up period, even in cold weather. Idling for more than 30 seconds wastes fuel and contributes to carbon buildup on the intake valves of EcoBoost engines.
Start the car, wait for the oil pressure to stabilize, and drive gently until the engine reaches operating temperature. This practice saves fuel and ensures that your catalytic converters reach their working temperature faster.
Advanced Troubleshooting: Sensors and Fuel Systems
If basic maintenance doesn’t fix your low MPGs, you may have a failing Oxygen (O2) sensor. These sensors monitor the exhaust gases and tell the computer if the engine is running “lean” or “rich.”
A “lazy” O2 sensor might not trigger a Check Engine Light immediately, but it can cause the engine to stay in a rich fuel loop. Using an OBD-II scanner to check live data can help you identify if a sensor is responding slowly.
Fuel injectors can also become clogged with deposits over time, especially if you use low-quality gasoline. Running a high-quality fuel system cleaner through a full tank of gas can help restore the spray pattern and improve combustion.
Checking for Brake Drag
Sometimes the problem isn’t the engine at all, but the chassis. A sticking brake caliper can create constant friction, significantly hurting the gas mileage for 2017 ford explorer owners.
After a drive, safely check for excessive heat coming from any of the wheels (do not touch the rotor directly). If one wheel feels significantly hotter than the others, you likely have a seized caliper or a failing wheel bearing.
Frequently Asked Questions About Gas Mileage for 2017 Ford Explorer
Does premium gas improve MPGs in the 2017 Explorer?
While the 2017 Explorer can run on 87 octane, using 91 or 93 octane is recommended for the EcoBoost engines. Higher octane prevents “knock” and allows the computer to optimize timing, which can lead to slightly better fuel efficiency and power.
How often should I change my spark plugs for better mileage?
Ford recommends changing plugs every 100,000 miles, but many enthusiasts suggest every 50,000 to 60,000 miles for EcoBoost engines. Fresh plugs ensure a strong spark, which is vital for maintaining peak fuel efficiency.
Will larger tires affect my gas mileage?
Yes, installing larger or heavier all-terrain tires will significantly decrease your MPGs. The increased weight and aggressive tread pattern create more rolling resistance and aerodynamic drag.
Is the “Instant MPG” gauge on the dashboard accurate?
The dashboard gauge provides a good estimate, but it is often slightly optimistic. For the most accurate reading, calculate your actual MPGs manually by dividing the miles driven by the gallons pumped at your next fill-up.
Summary of Key Efficiency Takeaways
Maximizing your fuel economy requires a combination of regular maintenance and mindful driving. Start with the basics: check your tire pressure and replace your air filter to ensure the engine isn’t fighting for air.
Don’t ignore the small things like cleaning your MAF sensor or managing the weight in your cargo area. These minor adjustments can add up to an extra 2-3 miles per gallon, saving you hundreds of dollars over a year of driving.
If you suspect a mechanical issue is dragging down your numbers, use an OBD-II tool to look for “pending” codes. Addressing a faulty sensor early can prevent more expensive repairs to your exhaust system or engine later on.
The 2017 Ford Explorer remains a capable and comfortable SUV for any adventure. By staying proactive with your maintenance, you can enjoy its power without constantly worrying about the next gas station. Stay safe and keep your Explorer running at its peak!
