2017 Ford Explorer Mileage – Realistic Mpg Expectations
The 2017 Ford Explorer offers fuel efficiency that varies significantly between its three available engine options, typically ranging from 16 to 27 MPG. This guide provides a detailed breakdown of real-world performance, maintenance factors that impact your fuel range, and DIY steps to optimize your SUV’s efficiency.
You likely chose the Explorer because you need a versatile vehicle that can handle the carpool lane just as easily as a weekend camping trip. However, many owners find that the actual fuel costs at the pump are higher than they initially anticipated during the purchase.
I am going to show you exactly what to expect from each powertrain and how to identify the hidden “mileage killers” that might be draining your tank. By understanding the technical nuances of your specific engine, you can make informed decisions about maintenance and driving habits.
We will dive into the differences between the EcoBoost and naturally aspirated engines, explore the impact of 4WD systems, and provide a step-by-step maintenance checklist. This guide is designed to help you maximize your 2017 ford explorer mileage while keeping your vehicle in peak mechanical condition.
Understanding the 2017 ford explorer mileage by Engine Type
The 2017 model year was a sweet spot for the Explorer, offering a variety of engines tailored to different needs. To accurately track your 2017 ford explorer mileage, you first need to identify which heart beats under the hood of your SUV.
The 3.5L Ti-VCT V6 (The Reliable Workhorse)
This naturally aspirated engine is found in many Base, XLT, and Limited trims. It is known for its simplicity and long-term reliability, but it is not the most fuel-efficient option in the lineup.
On average, you can expect about 17 MPG in the city and 24 MPG on the highway for FWD models. If you have the Intelligent 4WD system, those numbers usually drop by about 1 MPG across the board due to the added weight and mechanical drag.
The 2.3L EcoBoost I-4 (The Efficiency Leader)
If you prioritize fuel economy, this turbocharged four-cylinder is the top performer. It was designed to provide V6-like power while sipping fuel more conservatively during highway cruising.
Under ideal conditions, the 2.3L EcoBoost can reach up to 27 MPG on the highway. However, real-world drivers often report closer to 22-23 MPG in mixed driving, especially if the turbocharger is frequently engaged by a heavy foot.
The 3.5L EcoBoost V6 (The Performance Powerhouse)
Standard on the Sport and Platinum trims, this twin-turbocharged engine is built for speed and towing capacity. Unfortunately, performance comes at a cost to your wallet at the gas station.
Expect around 16 MPG in the city and 22 MPG on the highway. Because this engine encourages spirited driving, many owners find their combined average hovering around 18 MPG, particularly when navigating hilly terrain or carrying a full load of passengers.
Real-World Factors That Impact Your Fuel Economy
EPA ratings are calculated in a laboratory setting, but your daily commute involves variables that the lab cannot replicate. Understanding these factors helps you manage your expectations for 2017 ford explorer mileage in different scenarios.
Driving Habits and Idle Time
The Explorer is a heavy vehicle, weighing between 4,400 and 4,900 pounds. Frequent “jackrabbit” starts from a stop sign force the engine to burn excessive fuel just to overcome static inertia.
Additionally, excessive idling is a major culprit for poor efficiency. If you are waiting in a school pickup line or warming up the car for 15 minutes in the winter, your “miles per gallon” is effectively zero during that time.
Payload and External Aerodynamics
Adding a roof rack or a cargo box creates significant wind resistance, especially at speeds over 60 MPH. This can slash your highway efficiency by as much as 10% to 15%.
Similarly, carrying unnecessary gear in the back adds weight. For every 100 pounds of extra cargo, your fuel economy can dip by about 1%, which adds up over a long cross-country road trip.
The Role of the Power Transfer Unit (PTU)
In 4WD models, the Power Transfer Unit sends power to the rear wheels. If the fluid in this unit breaks down, it can create internal friction and drag, which subtly reduces your overall efficiency.
Many mechanics recommend changing the PTU fluid every 30,000 miles, even if Ford claims it is “lifetime” fluid. Keeping this component well-lubricated ensures that the drivetrain operates with minimal resistance.
Essential Maintenance to Improve 2017 Ford Explorer Efficiency
If you notice a sudden drop in your fuel range, it is usually a sign that a specific component is underperforming. Regular DIY maintenance is the most effective way to restore your engine’s original performance levels.
Cleaning the Mass Air Flow (MAF) Sensor
The MAF sensor tells the engine’s computer how much air is entering the intake. If it gets dusty or oily, the computer may overcompensate by injecting too much fuel, leading to a “rich” condition.
Use a dedicated MAF Sensor Cleaner spray to gently clean the delicate wires inside the sensor. Never use brake cleaner or carb cleaner, as these can melt the plastic or damage the sensitive electronics.
Replacing Old Spark Plugs and Ignition Coils
For the EcoBoost engines, spark plugs are under high pressure and heat. Over time, the gap between the electrodes widens, leading to incomplete combustion and wasted fuel.
I recommend replacing spark plugs every 40,000 to 50,000 miles on turbocharged models, even if the manual suggests a longer interval. Use a 5/8″ spark plug socket and a torque wrench to ensure they are seated perfectly to avoid misfires.
Monitoring Tire Pressure and Alignment
Under-inflated tires have a larger “footprint,” which increases rolling resistance. Check your door jamb sticker for the correct PSI (usually 35 PSI for the 2017 Explorer) and adjust them when the tires are cold.
Furthermore, if your SUV pulls to one side, your alignment is likely off. Misaligned wheels act like a “scrubbing” force against the pavement, forcing the engine to work harder to maintain forward momentum.
Troubleshooting Common Problems Affecting Mileage
Sometimes, maintenance isn’t enough, and you have to dig deeper into mechanical issues. These problems are common in high-mileage 2017 Explorers and can drastically affect your fuel consumption.
Dealing with Carbon Buildup on EcoBoost Engines
Because the 2.3L and 3.5L EcoBoost engines use Direct Injection, fuel does not wash over the intake valves. Over time, carbon deposits bake onto the valves, restricting airflow and reducing efficiency.
If you notice a rough idle or a loss of power, you may need a professional intake valve cleaning. Using high-quality Top Tier fuel can help slow this process, but it won’t prevent it entirely in high-mileage vehicles.
Checking for Sticking Brake Calipers
A brake caliper that doesn’t fully retract will cause the brake pad to stay in contact with the rotor. This creates constant friction that the engine must fight against while you drive.
After a drive, safely check for excessive heat coming from any one wheel (be careful not to touch the rim directly). If one wheel feels significantly hotter than the others, you likely have a seized caliper or a collapsed brake hose.
DIY Optimization Checklist for Owners
To keep your SUV running efficiently, follow this simple checklist every few months. These small steps ensure that you are getting the best possible 2017 ford explorer mileage for your specific driving conditions.
- Check the Air Filter: A clogged filter starves the engine of oxygen. Hold it up to a bright light; if you can’t see light through it, replace it immediately.
- Use the Right Oil: Always use the viscosity recommended on your oil cap (usually 5W-20 or 5W-30). Using thicker oil increases internal friction within the engine.
- Scan for Hidden Codes: Use a basic OBD-II scanner to check for “pending” codes. Sometimes a faulty oxygen sensor won’t trigger a check engine light but will still tank your MPG.
- Inspect the Fuel Cap: A worn-out seal on the capless fuel filler neck can allow fuel vapors to escape, which triggers the evaporative emissions system to run inefficiently.
Frequently Asked Questions About 2017 ford explorer mileage
Does premium gas improve my mileage?
For the naturally aspirated 3.5L V6, premium gas offers little to no benefit. However, for EcoBoost engines, higher octane fuel can prevent engine knock and allow the computer to optimize timing, which may slightly improve MPG under heavy loads.
How does towing affect my fuel range?
When towing a trailer near the Explorer’s 5,000-pound limit, expect your fuel economy to drop into the single digits (8-11 MPG). The engine must stay in “boost” longer to maintain speed, which consumes significant amounts of gasoline.
Will larger off-road tires hurt my MPG?
Yes, switching to heavy All-Terrain or Mud-Terrain tires increases both weight and rolling resistance. You can expect a loss of 1-3 MPG depending on the size and tread pattern of the new tires.
Is the 2.3L EcoBoost better than the V6 for city driving?
In stop-and-go traffic, the 2.3L EcoBoost generally performs better because it is a smaller displacement engine. However, the difference is less noticeable in the city than it is on the open highway.
Final Thoughts on Maximizing Your SUV’s Range
Achieving the best possible fuel economy in your Explorer is a combination of diligent maintenance and mindful driving. While the 2017 model is a large vehicle, it is capable of respectable efficiency when the mechanical systems are properly cared for.
Start by addressing the “low hanging fruit” like tire pressure and air filters. If your fuel consumption remains high, move on to cleaning sensors or inspecting the spark plugs to ensure clean combustion.
Remember that every small adjustment adds up over thousands of miles. By staying proactive with your repairs and keeping an eye on your dashboard’s fuel economy display, you can enjoy the power and comfort of your SUV without breaking the bank. Stay safe and stay comfortable!
