Performing a regular oil change on your Ford Explorer is the single most effective way to prevent premature wear on your EcoBoost or Ti-VCT engine. This guide walks you through the tools, steps, and expert tricks to ensure your SUV stays reliable whether you are commuting or hitting the trails.
Do you want your Ford Explorer to reach that 200,000-mile milestone without a major mechanical failure? Most owners agree that the secret to longevity is consistency in basic maintenance, specifically regarding the lubrication system. I promise that by following this professional-grade walkthrough, you will save money and gain the peace of mind that comes with knowing the job was done correctly.
In the following sections, we will preview the exact tools you need, the step-by-step drainage and filling process, and how to handle the specific quirks of the different Explorer generations. Whether you drive a 5th Gen with the 3.5L V6 or a newer 6th Gen with the 2.3L EcoBoost, this guide has you covered.
Taking care of a ford explorer oil change is a rite of passage for any DIY mechanic. It allows you to inspect the undercarriage for potential issues before they become expensive repairs on the side of the road.
Essential Tools and Supplies for the Job
Before you crawl under your vehicle, gather everything you need to avoid mid-job trips to the parts store. Having the right equipment makes the process faster and much cleaner. You do not need a professional lift, but a few specific items are non-negotiable for a safe experience.
First, you need a high-quality socket set. Most Ford Explorer models use a 13mm or 15mm socket for the oil pan drain plug. I recommend using a six-point socket to prevent rounding off the edges of the bolt, which is a common headache for high-mileage vehicles.
Next, invest in a sturdy oil filter wrench. Depending on your engine, the filter might be tucked away in a tight spot. A “cup-style” wrench that fits over the end of the filter or a “spider” grip wrench usually works best for the Motorcraft filters Ford specifies.
- Oil Drain Pan: Ensure it has at least a 7-quart capacity to handle the volume.
- Funnel: A long-neck funnel prevents spills on the hot exhaust manifold.
- Nitrile Gloves: Protect your skin from used motor oil, which contains carcinogens and heavy metals.
- Shop Rags: Keep plenty of these nearby for the inevitable drips.
- Jack and Jack Stands: Never work under a vehicle supported only by a hydraulic jack.
Choosing the Right Oil and Filter
Your Ford Explorer is sensitive to oil quality, especially if you have a turbocharger. For most modern Explorers, Ford recommends Motorcraft Full Synthetic or Synthetic Blend. Check your owner’s manual for the specific weight, usually 5W-20 or 5W-30.
Always use a high-quality filter like the Motorcraft FL-500S or FL-820S. These filters feature a silicone anti-drain back valve. This valve keeps oil in the upper engine during shutdown, preventing “dry starts” that cause clatter and wear on your timing chain.
Step-by-Step Ford Explorer Oil Change Process
Safety is your primary concern when starting a ford explorer oil change. Park the vehicle on a level surface and engage the parking brake. If you are using ramps, ensure they are rated for the weight of a mid-size SUV.
Run the engine for about five minutes before you start. Warm oil flows much faster and carries away more contaminants than cold, sluggish oil. However, be careful not to get the engine “operating temperature” hot, or you risk burning your hands on the drain plug.
1. Accessing the Underbody
Lift the front of the vehicle and secure it on jack stands. If you have a newer 6th Gen Explorer or an off-road trimmed model, you might need to remove a plastic or metal skid plate or “aerodynamic shield.” These are usually held on by several 7mm or 8mm bolts and a few plastic push-pins.
Removing this shield is the most tedious part of the job. Use an electric screwdriver or a small impact driver to speed this up. Once the shield is off, you will have a clear view of the oil pan and the filter housing.
2. Draining the Old Oil
Position your drain pan directly under the drain plug. Remember that the oil will shoot out at an angle initially, so offset the pan slightly toward the rear of the vehicle. Use your wrench to loosen the plug, then finish unscrewing it by hand. Pro Tip: Apply inward pressure on the plug as you unscrew the last few threads. This prevents oil from leaking out until you are ready to pull the plug away quickly. This technique keeps your hands clean and reduces splashing.
3. Replacing the Filter
While the oil is finishing its slow drip, move the pan under the oil filter. Loosen the filter with your wrench. Once it is loose, let the oil drain from the filter for a minute before removing it completely. Be prepared; Ford often places the filter near the front subframe, and oil can run down the frame and make a mess.
Before installing the new filter, take a clean rag and wipe the mounting surface on the engine block. Ensure the old rubber gasket did not stick to the block. If you “double-gasket” the filter, it will blow out under pressure and dump all your new oil in seconds.
Dip your finger in clean oil and lubricate the rubber seal on the new filter. This ensures a proper seal and makes it easier to remove next time. Hand-tighten the filter until it makes contact, then give it another three-quarters of a turn. Do not use a wrench to tighten it.
4. Refilling the System
Reinstall the drain plug. If the washer looks crushed or distorted, replace it with a new one to prevent slow leaks. Tighten the plug to approximately 20-25 lb-ft of torque. You want it snug, but do not over-torque it, as the aluminum threads in the pan can strip easily.
Locate the oil fill cap on top of the engine. Use your funnel to pour in the required amount of oil. For a 3.5L Ti-VCT engine, this is usually 6 quarts. For the 2.3L EcoBoost, it is typically around 5.7 to 6 quarts. Always verify with your dipstick after filling.
EcoBoost vs. Naturally Aspirated Engines
The Ford Explorer has utilized several different engine architectures over the years. Understanding which one you have is vital for choosing the right parts. The EcoBoost engines use turbochargers that rely on engine oil for cooling and lubrication of the turbine shaft.
Because turbochargers operate at incredibly high speeds and temperatures, they are prone to carbon buildup if the oil is not changed frequently. If you drive an EcoBoost model, I strongly recommend using a full synthetic oil. Synthetic oils resist “thermal breakdown” much better than conventional oils.
Naturally aspirated engines, like the older 4.0L V6 or the 3.5L Ti-VCT, are a bit more forgiving but still benefit from high-quality lubricants. If you have the 3.5L V6, pay close attention to the internal water pump. While not directly related to an oil change, checking your oil for a “milky” appearance can alert you to a failing water pump seal before it destroys the engine.
Off-Road and Heavy Towing Maintenance
If you use your Explorer for overlanding, beach driving, or towing a heavy camper, your maintenance schedule needs to be more aggressive. Ford defines this as “Severe Duty” service. Dust, mud, and high heat degrade oil much faster than highway cruising.
During a ford explorer oil change after an off-road trip, take an extra ten minutes to inspect the chassis. Check the CV boots for tears and look for debris trapped near the exhaust. Dust can also clog your air filter, which forces the engine to work harder and can lead to fuel dilution in the oil.
For those who frequently tow, consider an oil analysis service. Sending a small sample of your used oil to a lab can reveal the health of your engine bearings and tell you if your 5,000-mile interval is actually sufficient for your driving style.
- Dusty Trails: Change the engine air filter every time you change the oil.
- Water Crossings: If you submerged the axles, check your differential fluid for water contamination.
- High Heat: Use a premium synthetic oil with a high viscosity index to maintain protection.
Resetting the Intelligent Oil-Life Monitor
Modern Ford Explorers feature an Intelligent Oil-Life Monitor (IOLM). This system does not just count miles; it calculates oil depletion based on engine temperatures, idle time, and driving habits. Once you finish the mechanical work, you must tell the computer the oil is new.
The process varies slightly by year, but generally, you will use the steering wheel buttons to navigate the Information Display. Go to “Settings,” then “Vehicle,” and look for “Oil Life Reset.” Hold the “OK” button until the system shows 100%.
Do not reset this monitor unless you have actually changed the oil. Relying on the computer without doing the physical work is a recipe for engine sludge. If you prefer a fixed interval, many enthusiasts choose to change their oil every 5,000 miles regardless of what the monitor says, especially on turbocharged models.
Troubleshooting Common Issues
Even a simple job can go wrong. One of the most common issues is a stuck oil filter. If the previous person over-tightened it or didn’t lubricate the gasket, it might refuse to budge. If a standard wrench fails, a “claw” style extractor that bites into the filter metal usually does the trick.
Another common problem is a stripped drain plug. If you feel the bolt “let go” while tightening, the threads in the oil pan may be damaged. In an emergency, you can use an oversized self-tapping plug, but the permanent fix is usually replacing the entire oil pan.
Dealing with Oil Spills
If you spill oil on the driveway, act quickly. Use kitty litter or a specialized absorbent floor sweep to soak up the liquid. Grind it into the pavement with your shoes to lift the oil out of the pores of the concrete. This prevents staining and keeps your workspace safe.
Check for leaks immediately after starting the engine. Let it idle for two minutes and look under the vehicle. A small drip now can become a catastrophic leak at highway speeds. Ensure the oil pressure light on the dashboard turns off within a few seconds of startup.
Frequently Asked Questions About Ford Explorer Oil Changes
How much oil does a Ford Explorer take?
The capacity depends on the engine. The 2.3L EcoBoost and 3.5L V6 typically require 5.7 to 6.0 quarts. The newer 3.0L EcoBoost found in the ST models requires about 6.0 quarts. Always check your specific owner’s manual or the printed capacity on the under-hood sticker.
How often should I change the oil in my Ford Explorer?
While the IOLM may allow for up to 10,000 miles, most mechanics recommend a 5,000 to 7,500-mile interval. If you do a lot of short trips or off-roading, stick to the 5,000-mile mark to prevent sludge buildup and protect the turbochargers.
Can I use 5W-30 instead of 5W-20?
You should generally stick to what is on the oil fill cap. Ford engineers specify the weight based on the tolerances of the variable valve timing (VCT) solenoids. Using the wrong weight can occasionally trigger a Check Engine Light or reduce fuel economy.
What is the best oil filter for a Ford Explorer?
The Motorcraft FL-500S is widely considered the best choice. It is the OEM part designed specifically for the pressure relief requirements of Ford engines. Avoid cheap “no-name” filters that may have inferior filtration media or weak bypass springs.
