Understanding Your 2018 Ford Explorer Fuel Capacity
Let’s get straight to the heart of the matter: what’s the actual tank size? The 2018 Ford Explorer, across all its trim levels and engine options, comes equipped with a consistent fuel tank.
Standard Fuel Tank Size
Every 2018 Ford Explorer model is fitted with an 18.6-gallon (approximately 70.4 liters) fuel tank. This standard capacity provides a respectable driving range, suitable for most daily driving needs and longer journeys.
It’s a generous size that allows for fewer stops at the pump, which is a real bonus on those extended highway cruises or when you’re far from urban centers.
Engine Variations and Their Impact on Range
While the fuel tank size remains constant, the type of engine under your Explorer’s hood significantly influences how far that 18.6 gallons will take you. Ford offered a few robust options for the 2018 model year:
- 2.3L EcoBoost I-4: This turbocharged four-cylinder engine is known for its balance of power and efficiency. It generally offers the best fuel economy among the Explorer’s engine choices.
- 3.5L Ti-VCT V6: The naturally aspirated V6 is a reliable workhorse, providing solid performance. Its fuel economy is typically a bit lower than the 2.3L EcoBoost.
- 3.5L EcoBoost V6: Found in the Sport and Platinum trims, this twin-turbo V6 delivers impressive power and acceleration. However, that performance comes at the cost of lower fuel efficiency.
Understanding your specific engine is crucial for accurately estimating your driving range. A 2.3L EcoBoost Explorer will stretch that 18.6-gallon capacity further than a 3.5L EcoBoost Sport model.
Fuel Type Recommendations
For all 2018 Ford Explorer engines, Ford recommends using regular unleaded gasoline with an octane rating of 87. This is the most common and cost-effective fuel type available.
While the 3.5L EcoBoost V6 can handle premium fuel (91 octane or higher) for slightly improved performance, it’s not strictly required. Sticking to the recommended 87 octane will not harm your engine and is usually the most economical choice.
Always double-check your owner’s manual for the precise fuel recommendations for your specific vehicle configuration. Using the correct fuel ensures optimal engine performance and longevity.
Calculating Your Real-World Driving Range
Knowing your tank size is just the beginning. The true magic lies in understanding your vehicle’s actual driving range. This isn’t just about the sticker MPG; it’s about how you drive and where you drive.
Beyond the Sticker: MPG Factors
The EPA estimates for your Explorer’s MPG are a great starting point, but real-world conditions often vary. Many factors influence how many miles you’ll get from a full tank:
- Driving Style: Aggressive acceleration, hard braking, and excessive speeding are major fuel guzzlers. Smooth, consistent driving is your best friend for efficiency.
- Terrain: Driving uphill or on rugged, unpaved roads requires more power and thus more fuel. Off-road trails will drastically reduce your MPG.
- Load and Towing: A fully loaded vehicle with passengers and cargo, or towing a trailer, puts extra strain on the engine, increasing fuel consumption.
- Weather Conditions: Strong headwinds, heavy rain, or snow can decrease fuel economy. Extreme cold weather also impacts engine efficiency during warm-up.
- Vehicle Maintenance: A poorly maintained engine, clogged air filter, or underinflated tires can all lead to worse MPG.
Keep these variables in mind when you’re planning your next adventure. A little foresight can save you from a roadside predicament.
The Fuel Gauge: Trust It, But Verify
Your Explorer’s fuel gauge is generally reliable, but it’s an estimate, not a precise measurement. Most vehicles have a “reserve” capacity once the low fuel light comes on, typically 1-2 gallons.
However, don’t push your luck. Running your tank consistently low can put extra strain on your fuel pump, potentially shortening its lifespan. The fuel pump relies on the gasoline around it for cooling, and running it dry can cause it to overheat.
A good practice is to refuel when your gauge reads around a quarter tank. This gives you a buffer and protects your fuel system components.
Planning for Off-Road and Remote Travel
For off-road enthusiasts or those heading into remote wilderness, fuel planning is paramount. Your Explorer’s 18.6-gallon tank might feel ample on the highway, but difficult terrain chews through fuel much faster.
When planning an off-road trip:
- Estimate Conservatively: Assume your MPG will be significantly lower than highway averages, perhaps by 30-50% or more, depending on the trail difficulty.
- Map Out Fuel Stops: Identify gas stations along your route, especially before entering remote areas. Don’t rely on finding one “just in case.”
- Consider Extra Fuel: For extended backcountry trips, carrying an approved jerry can (or two) of extra fuel is a smart move. Secure it properly outside the vehicle to prevent fumes inside the cabin.
- Communicate Your Plans: Always let someone know your route and expected return time, especially if you’re venturing into areas with no cell service.
Running out of fuel in the wilderness is more than an inconvenience; it can be a safety hazard. Always prioritize preparation and safety over convenience.
Maximizing Fuel Efficiency: Pro Tips for Your Explorer
Even with a fixed 2018 Ford Explorer fuel capacity, you have a lot of control over how efficiently you use that fuel. Here are some expert tips to stretch every gallon.
Driving Habits That Save Gas
Your driving style is the biggest factor you can control when it comes to fuel economy. Adopt these habits for better MPG:
- Smooth Acceleration and Braking: Avoid sudden starts and stops. Accelerate gently and anticipate traffic to brake smoothly. This reduces engine strain and wasted energy.
- Maintain a Consistent Speed: Use cruise control on highways to avoid speed fluctuations. Rapid changes in speed burn more fuel.
- Observe Speed Limits: Fuel efficiency generally drops significantly above 60-65 mph. Driving at or slightly below the speed limit can make a big difference.
- Avoid Excessive Idling: If you’re going to be stopped for more than 30 seconds, it’s often more fuel-efficient to turn off your engine and restart it when ready to go.
These small changes in habit can add up to significant fuel savings over time, giving you more miles for your money.
Maintenance Matters: Fuel System Health
A well-maintained vehicle is an efficient vehicle. Regular maintenance is crucial for optimal fuel economy:
- Check and Replace Air Filter: A clean air filter ensures your engine gets enough air for proper combustion. A clogged filter restricts airflow, forcing the engine to work harder and use more fuel. Check it during every oil change and replace as needed.
- Spark Plugs: Worn or dirty spark plugs can lead to misfires and inefficient combustion. Replace them according to your owner’s manual schedule, typically every 60,000 to 100,000 miles.
- Fuel Injector Cleaning: Over time, fuel injectors can become clogged with deposits, leading to poor fuel atomization and reduced efficiency. Consider using a quality fuel system cleaner every few oil changes or having them professionally cleaned if you notice a drop in performance or MPG.
- Oxygen Sensors: Faulty oxygen sensors can send incorrect data to your engine’s computer, leading to an overly rich fuel mixture and wasted gas. If your check engine light comes on, have it diagnosed promptly.
Staying on top of your Explorer’s maintenance schedule is one of the best investments you can make for its long-term health and your wallet.
Tire Pressure and Aerodynamics
Don’t underestimate the impact of your tires and vehicle’s external features on fuel efficiency:
- Proper Tire Inflation: Underinflated tires increase rolling resistance, forcing your engine to work harder. Check your tire pressure regularly (at least once a month, when tires are cold) and inflate to the recommended PSI found on the sticker inside your driver’s side door jamb.
- Remove Unnecessary Weight: Every extra pound your Explorer carries reduces fuel economy. Clear out any unneeded items from your trunk or cabin.
- Reduce Aerodynamic Drag: Roof racks, cargo carriers, or even open windows at highway speeds create drag. Remove roof accessories when not in use and keep windows closed on the highway to improve aerodynamics.
These often-overlooked details can collectively improve your fuel economy by several percentage points, making your 18.6-gallon tank go further.
Common Fuel-Related Issues and Troubleshooting
Even the most reliable vehicles can encounter fuel system issues. Knowing what to look for can help you diagnose problems early and prevent bigger headaches.
Inaccurate Fuel Gauge Readings
If your fuel gauge seems to be giving you inconsistent or incorrect readings, there are a few potential culprits:
- Fuel Level Sending Unit: This component, usually located inside the fuel tank, measures the fuel level. If it’s faulty, it can send inaccurate signals to your dashboard gauge.
- Dashboard Instrument Cluster: Less common, but sometimes the issue lies with the gauge itself or the wiring in the instrument cluster.
- Electrical Issues: Corrosion or loose connections in the wiring harness connected to the sending unit can also cause intermittent readings.
If you suspect an inaccurate gauge, it’s best to track your mileage after a fill-up and compare it to your usual driving range. If the problem persists, a professional diagnosis is recommended.
Fuel System Leaks: What to Look For
A fuel leak is a serious safety concern and should be addressed immediately. Here are signs to watch for:
- Smell of Gasoline: The most obvious sign. If you smell gas inside or around your Explorer, especially after filling up, investigate immediately.
- Puddles Under the Vehicle: Look for reddish-brown or yellowish liquid on the ground where your car was parked. Gasoline has a distinct smell and appearance.
- Reduced Fuel Economy: If your MPG suddenly drops without a change in driving habits, a leak could be contributing to the loss of fuel.
- Check Engine Light: A fuel system leak can trigger the check engine light, often with an EVAP system (Evaporative Emission Control System) related code.
If you discover a fuel leak, do not drive the vehicle. Fuel is highly flammable. Call a tow truck and have it taken to a qualified mechanic for immediate repair. This is not a DIY job.
When to Call a Professional Mechanic
While DIY maintenance is great for many tasks, some fuel system issues are best left to licensed professionals:
- Persistent Check Engine Light: Especially if accompanied by a fuel-related code. A professional can accurately diagnose the underlying issue.
- Fuel Leaks: As mentioned, these are dangerous and require expert attention.
- Fuel Pump Replacement: This is a complex job that often involves dropping the fuel tank, requiring specialized tools and safety precautions.
- Complex Diagnostic Issues: If you’ve performed basic checks and can’t pinpoint the problem, a mechanic with diagnostic equipment can identify the root cause.
Your safety and the proper functioning of your vehicle depend on getting these critical systems repaired correctly.
Safety First: Handling Fuel and Emergencies
Fuel is a powerful and volatile substance. Always treat it with respect and follow safety guidelines, especially when dealing with emergencies or carrying extra fuel.
Carrying Extra Fuel Safely
For those long hauls or off-road adventures where gas stations are scarce, carrying extra fuel can be a lifesaver. However, it must be done safely:
- Use Approved Containers: Always use red, DOT-approved plastic or metal jerry cans specifically designed for gasoline. These are built to be durable and minimize spills and fumes.
- Secure Outside the Vehicle: Never carry extra fuel inside the passenger cabin. Fumes can build up and are extremely dangerous. Secure cans tightly in a roof rack or a sturdy cargo carrier mounted on the hitch.
- Fill Correctly: Do not overfill containers. Leave a small air gap for expansion, especially in warm weather.
- Ventilate: If you must temporarily transport a can inside, ensure windows are open for maximum ventilation and keep the journey short.
- Avoid Heat/Sparks: Keep fuel cans away from direct sunlight, heat sources, and any potential ignition sources like open flames or sparks.
A little preparation goes a long way in preventing hazardous situations.
Emergency Fueling Procedures
If you find yourself stranded with an empty tank, here’s how to handle it safely:
- Pull Over Safely: Get your vehicle off the road as far as possible, preferably on level ground. Turn on your hazard lights.
- Wait for the Engine to Cool: Before adding fuel, allow the engine and exhaust system to cool down to reduce fire risk.
- Use a Funnel: Always use a proper funnel to prevent spills. Static electricity can be a risk, so ensure the funnel or fuel nozzle makes contact with the filler neck to ground it.
- Avoid Spills: Pour slowly and carefully. If any fuel spills on your vehicle’s paint, wipe it off immediately to prevent damage.
- Secure Cap: Once fueled, ensure your gas cap is securely tightened.
If you’re in a remote area and need help, contact roadside assistance or, if available, local park rangers or experienced guides who can assist safely.
Preventing Fuel Spills and Fires
Prevention is key when it comes to fuel safety:
- Tighten Gas Cap: Always ensure your gas cap is tightened until it clicks after refueling. This prevents fuel vapor from escaping and helps maintain proper pressure in the fuel system.
- No Smoking at the Pump: This is a fundamental rule for a reason. Keep all ignition sources away from fuel.
- Ground Yourself: If you’re wearing synthetic clothing, static electricity can build up. Touch a metal part of your vehicle before grabbing the fuel nozzle to discharge any static.
- Don’t Top Off: Stop fueling when the pump automatically clicks off. Overfilling can lead to spills, especially in warm weather, and can damage your vehicle’s EVAP system.
Following these simple guidelines can prevent accidents and ensure your fueling experiences are always safe.
