2018 Ford Explorer Miles Per Gallon – How To Maximize Your Real-World
The 2018 Ford Explorer typically delivers between 16 and 22 MPG combined, depending on the engine choice and drivetrain configuration. Achieving these numbers in real-world conditions requires a mix of proper engine maintenance, smart driving habits, and managing vehicle weight during trips.
You bought the Ford Explorer because you needed a versatile hauler that could handle the school run during the week and a mountain trailhead on the weekend. But like many owners, you have probably noticed that the 2018 ford explorer miles per gallon figures fluctuate wildly depending on how you use the vehicle.
It is frustrating to watch the fuel gauge drop faster than expected when you are planning a long road trip or just commuting through stop-and-go traffic. Understanding how to optimize your efficiency is not just about saving money; it is about keeping your SUV running at its peak performance level.
In this guide, we will break down exactly what you can expect from your engine, how to diagnose hidden efficiency killers, and the professional-grade tweaks that help you squeeze every last mile out of your tank.
Understanding the 2018 ford explorer miles per gallon Estimates
Ford offered three distinct engine options for the 2018 model year, each with a different footprint on your wallet. Knowing which powertrain you have under the hood is the first step toward managing your fuel consumption effectively.
The base 3.5L Ti-VCT V6 is the workhorse of the lineup. It is reliable and simple, but it is also the thirstiest, often averaging around 17 MPG combined. The 2.3L EcoBoost four-cylinder is the efficiency leader, designed to balance power with better thermal management, typically hitting the 20-22 MPG range.
Finally, the 3.5L EcoBoost V6—found in the Sport and Platinum trims—is all about torque. While it is incredibly capable for towing or highway passing, it will be the most sensitive to heavy-footed driving styles. If you push the twin turbos hard, your economy will plummet quickly.
The Impact of Drivetrain and Weight
The Intelligent 4WD system on the Explorer is a masterpiece of engineering, but it adds significant mechanical drag. If you spend 90% of your time on dry pavement, the added weight and friction of the transfer case and front differential will keep your numbers on the lower end of the spectrum.
Payload also plays a massive role. If you are an off-road enthusiast, that roof rack, heavy-duty spare tire, and extra recovery gear add up to hundreds of pounds. Every 100 pounds of extra weight can reduce your fuel economy by roughly 1-2%, so keep your cargo lean unless you are heading out on an expedition.
Common Maintenance Factors Affecting Your Fuel Consumption
A vehicle that is out of tune is a vehicle that wastes fuel. If you are noticing that your 2018 ford explorer miles per gallon have dropped over the last few months, it is time to look at the basics of your engine’s health.
Start with your air filter. If your engine cannot breathe, the computer compensates by dumping more fuel into the combustion chamber to maintain the desired power output. A clogged filter is a major thief of efficiency, so check it every 10,000 miles.
Next, consider your spark plugs. On the EcoBoost models, these plugs operate under high pressure and heat. If they are worn, you will experience incomplete combustion, which means you are literally burning fuel that isn’t providing any forward momentum.
Tire Pressure and Alignment
Your tires are the only thing connecting your Explorer to the road. If they are under-inflated, the increased rolling resistance forces your engine to work harder to maintain speed. Use a reliable digital tire gauge to ensure you are at the manufacturer’s recommended PSI found on the driver’s side door jamb.
Furthermore, an out-of-spec alignment will cause your tires to scrub sideways rather than roll straight. Even a slight misalignment can drag your efficiency down significantly. If you notice uneven tire wear or the vehicle pulling to one side, get it to a shop for a professional alignment.
Driving Habits for Better Efficiency
You can have the most perfectly tuned engine in the world, but your driving style will always be the biggest variable. Modern SUVs like the Explorer are tuned for fuel efficiency during steady-state cruising, but they struggle when subjected to aggressive acceleration.
The EcoBoost engines are designed to provide torque at low RPMs. You do not need to bury the pedal to get up to highway speed. Use a light touch on the throttle, and let the turbochargers spool up gradually. This prevents the engine from entering “power-rich” mode, where it dumps extra fuel to cool the cylinders.
- Anticipate Traffic: Coasting toward a red light instead of braking at the last second saves fuel and reduces wear on your brake pads.
- Use Cruise Control: On flat, open highways, the computer can maintain a more consistent speed than your foot, which is essential for highway fuel economy.
- Minimize Idle Time: If you are waiting for more than a minute, turn the engine off. Idling consumes fuel without moving you a single inch.
Off-Road and Heavy-Duty Considerations
If you take your Explorer off-road, you have to accept that your fuel economy will suffer. Driving on sand, mud, or steep inclines forces the transmission to stay in lower gears and keeps the engine in the high-RPM power band.
When you are out in the wild, prioritize safety over fuel efficiency. However, you can mitigate the impact by choosing the right terrain mode. The Terrain Management System optimizes the throttle and transmission response; using the “Sand” or “Mud/Ruts” mode on pavement will actually lower your efficiency, so ensure you switch back to “Normal” as soon as you hit the blacktop.
If you are towing a trailer, keep your speed moderate. The aerodynamic profile of the 2018 Explorer is great for a daily driver, but it creates a massive wake behind it when towing. Dropping your speed from 75 MPH to 65 MPH can improve your towing fuel economy by as much as 15%.
Advanced Diagnostics: When to See a Mechanic
Sometimes, a drop in 2018 ford explorer miles per gallon is caused by a failing component that hasn’t triggered a “Check Engine” light yet. Sensors like the Mass Air Flow (MAF) sensor or the Oxygen (O2) sensors can degrade over time.
A dirty MAF sensor can send incorrect data to the ECU, causing the engine to run “rich” (too much fuel) or “lean” (not enough air). You can clean the MAF with a specialized spray, but if the issue persists, a professional diagnostic tool can read the “fuel trim” values to see if the computer is struggling to balance the air-fuel mixture.
Another often overlooked culprit is a sticking brake caliper. If one of your wheels feels significantly hotter than the others after a drive, a caliper may be hanging up, creating constant drag. This is a safety issue that requires immediate attention from a qualified technician.
Frequently Asked Questions About 2018 ford explorer miles per gallon
Does using premium fuel improve my MPG?
For the EcoBoost engines, Ford recommends premium fuel for maximum performance. While you might see a slight increase in efficiency, the main benefit is the engine’s ability to run with more aggressive timing, which helps prevent engine knock under load.
How does the AC affect my fuel economy?
Running the air conditioning puts a load on the engine, which will decrease your fuel economy. In stop-and-go traffic, the impact is noticeable, but at highway speeds, it is often more efficient to run the AC than to drive with the windows down, which ruins the vehicle’s aerodynamics.
Why is my cold-weather MPG so much lower?
Cold air is denser, which changes the air-fuel ratio, and your engine takes longer to reach its optimal operating temperature. Additionally, winter-blend fuels often have slightly less energy content than summer-blend fuels, both of which contribute to lower numbers during the winter months.
Is there a “break-in” period for a used 2018 Explorer?
If you just bought a used model, it may take a few hundred miles of driving for the computer to “re-learn” your driving habits. Use this time to ensure your fluids are fresh, as clean synthetic oil reduces internal friction and helps the engine run more efficiently.
Managing your fuel economy is a rewarding part of owning a capable vehicle like the Ford Explorer. By staying on top of your maintenance schedule and keeping a light touch on the throttle, you ensure that your SUV stays reliable for years to come. Stay safe out there on the road, and enjoy every mile of your journey!
