Whether you are a DIY mechanic looking to optimize your rig or a daily driver trying to save at the pump, understanding the nuances of your powertrain is the first step. This guide will provide the technical insights and practical steps needed to improve your 2016 ford explorer sport gas mileage effectively.
We will explore the mechanical factors that influence fuel consumption, from spark plug gaps to aerodynamic drag. By the end of this article, you will have a clear roadmap for maintaining your Explorer’s efficiency without sacrificing the performance you love.
The Reality of 2016 ford explorer sport gas mileage and the EcoBoost Engine
The 2016 Ford Explorer Sport is a unique beast in the lineup because it exclusively features the 3.5L EcoBoost V6 and Intelligent 4WD. Unlike the naturally aspirated base models, the Sport relies on turbocharging and direct injection to move its 4,900-pound curb weight.
EPA estimates suggest a combined 18 MPG, but many owners report seeing closer to 14 or 15 MPG in heavy stop-and-go traffic. This discrepancy often stems from the engine’s tendency to stay “in boost” during acceleration, which requires a richer fuel mixture to maintain safe combustion temperatures.
To get the best 2016 ford explorer sport gas mileage, you must understand how to manage the relationship between the throttle and the turbochargers. Small changes in how you apply pressure to the gas pedal can result in a 2-3 MPG difference over a full tank of fuel.
The Impact of Intelligent 4WD on Efficiency
The Sport trim comes standard with an 4WD system that constantly monitors wheel slip and redistributes torque. While this is excellent for safety and off-road capability, the added mechanical drag of the transfer case and rear differential inherently lowers fuel economy.
Unlike older 4×4 systems, you cannot manually “turn off” the 4WD to save gas, as the system is always active. Ensuring the PTU (Power Transfer Unit) fluid is clean and the rear differential is serviced will minimize internal friction and help maintain efficiency.
Why Your Fuel Economy Might Be Dropping
If you have noticed a sudden dip in your miles per gallon, it is rarely a single “broken” part but rather a combination of small maintenance items. In a high-performance engine like the 3.5L EcoBoost, even a slight misfire or a clogged sensor can lead to significant fuel waste.
Common culprits include dirty air filters, aging spark plugs, or “winter blend” fuels that contain less energy per gallon. Additionally, the 2016 Explorer Sport is sensitive to aerodynamic changes, such as adding a roof-mounted cargo box or heavy off-road tires.
Identifying these issues early can save you hundreds of dollars in fuel costs over the year. Let’s look at the specific mechanical areas you should inspect to restore your vehicle’s factory-rated efficiency and performance.
Carbon Buildup on Intake Valves
Because the 2016 Explorer Sport uses Gasoline Direct Injection (GDI), fuel is sprayed directly into the combustion chamber rather than over the intake valves. Over time, oil vapors from the PCV system can bake onto the valves, restricting airflow and reducing efficiency.
This “carbon coking” can cause the engine to work harder, leading to a noticeable drop in MPG and occasional rough idling. Using a high-quality intake valve cleaner or installing a catch can are common DIY solutions used by enthusiasts to mitigate this problem.
Essential Maintenance Steps to Improve MPG
Maintaining a high-output engine requires more than just regular oil changes; it requires precision. To optimize your 2016 ford explorer sport gas mileage, you should start with the components that directly control the combustion process.
Begin by checking your engine air filter, as a restricted filter forces the turbos to work harder to pull in air. A clean, high-flow dry filter is often a better choice than an oiled filter, which can sometimes contaminate sensitive sensors downstream.
Next, inspect your tire pressure using a reliable digital gauge rather than the dashboard’s TPMS display, which may not be perfectly accurate. Running your tires at the recommended 35 PSI (or slightly higher for highway trips) reduces rolling resistance and improves fuel flow.
The Critical Role of Spark Plugs
The 3.5L EcoBoost is notoriously hard on spark plugs due to the high cylinder pressures generated by the twin turbochargers. For the best fuel economy, most experienced Ford technicians recommend replacing plugs every 30,000 to 40,000 miles, even if the manual says 100,000.
When installing new plugs, ensure they are gapped correctly to .030 inches; a gap that is too wide can cause “spark blow-out” under boost. Using the factory-recommended Motorcraft Iridium plugs ensures the ignition system operates exactly as the engineers intended for maximum efficiency.
Cleaning the MAP and MAF Sensors
Your Explorer uses multiple Manifold Absolute Pressure (MAP) sensors to calculate how much air is entering the engine. If these sensors become coated in oil or debris, the ECU may over-fuel the engine to compensate for inaccurate readings.
Using a dedicated electronic cleaner spray, you can carefully clean these sensors in about 20 minutes with basic hand tools. This simple DIY task can often restore lost MPG and improve throttle response without a trip to the dealership.
Advanced Troubleshooting for Performance and Savings
If basic maintenance doesn’t solve the problem, you may need to look deeper into the vehicle’s electronic and vacuum systems. A boost leak is a common issue where pressurized air escapes through a loose hose or a cracked plastic bypass valve.
When air escapes, the engine’s computer detects a lean condition and dumps extra fuel into the cylinders to prevent damage. This “rich” condition kills your fuel economy and can eventually lead to clogged catalytic converters, which are expensive to replace.
Using an OBD-II scan tool, you can monitor your “Long Term Fuel Trims” to see if the engine is adding more fuel than normal. If your trims are consistently above 10%, you likely have a vacuum leak or a failing upstream O2 sensor that needs attention.
Checking the Braking System for Drag
Sometimes the engine isn’t the problem; the wheels might be fighting against the brakes. A seized brake caliper or a sticking parking brake cable can create constant resistance that the engine must overcome.
After a long drive, safely use an infrared thermometer to check the temperature of your wheel hubs and brake rotors. If one wheel is significantly hotter than the others, you likely have a dragging brake that is actively sabotaging your fuel economy.
Driving Habits and Real-World Scenarios
Even the best-maintained 2016 Explorer Sport will get poor mileage if driven aggressively. The 3.5L EcoBoost engine is designed to provide instant torque, but that torque comes at a high fuel cost when you “floor it” from every stoplight.
To maximize efficiency, practice “driving with a vacuum gauge” in mind, even if you don’t have one installed. Smooth, gradual acceleration allows the 6-speed SelectShift transmission to upshift early, keeping the engine RPMs low and out of the heavy boost range.
When traveling on the highway, using Adaptive Cruise Control can help maintain a steady speed, which is much more efficient than constant manual adjustments. However, in very hilly terrain, it is often better to manage the throttle yourself to avoid unnecessary downshifts.
Off-Road and Towing Considerations
If you use your Explorer Sport for light off-roading or towing a trailer, your fuel economy will naturally plummet. When towing, the engine stays in a high-boost state to maintain speed, often dropping the MPG into the single digits.
For off-roaders, the added weight of skid plates, winches, and larger all-terrain tires increases both mass and wind resistance. If efficiency is a priority, choose “P-metric” tires over “LT-rated” tires, as the lighter weight significantly reduces the rotational mass the engine must spin.
Frequently Asked Questions About 2016 ford explorer sport gas mileage
Does using premium 91/93 octane fuel improve gas mileage?
Yes, the 2016 Explorer Sport’s ECU can advance ignition timing when it detects higher octane fuel, which improves efficiency under load. While the engine can run on 87 octane, you will likely see a 1-2 MPG increase and better performance when using premium fuel.
Can an aftermarket “tuner” or “chip” improve my MPG?
While some aftermarket tunes claim to improve fuel economy, they often do so by leaning out the fuel mixture, which can be risky for the engine. Most owners find that a performance tune actually decreases MPG because the increased power makes it more tempting to drive aggressively.
What is the most common reason for a sudden drop in Explorer Sport MPG?
The most common culprit is a faulty EVAP purge valve, which can cause the engine to pull in extra fuel vapors at the wrong time. This often presents as a “rough idle after refueling” and can significantly impact your overall fuel economy if not replaced.
Is 18 MPG a realistic average for this vehicle?
For a mix of 60% highway and 40% city driving, 18 MPG is very achievable if the vehicle is well-maintained and driven moderately. If you primarily drive in the city or have a heavy foot, you should expect an average closer to 15 or 16 MPG.
