Understanding the 2017 Ford Explorer 3.5 oil capacity is essential for maintaining the longevity and performance of this popular three-row SUV. The 3.5-liter EcoBoost engine, a powerhouse in its class, requires the correct volume of lubricant to ensure optimal operation and to prevent potential damage. This specific capacity is not a one-size-fits-all figure and varies slightly depending on the model year and trim, generally falling within a precise range that owners should be aware of.
Factory Specifications for the 3.5L EcoBoost
For the vast majority of 2017 Ford Explorer models equipped with the 3.5-liter EcoBoost engine, the total oil capacity is approximately 7.5 quarts. This figure includes the oil filter and the oil pan. It is always recommended to consult the vehicle's specific owner manual for the most accurate data, as variations exist between trimes such as the base XL and the higher-level Platinum or ST-Line trims. Using the correct capacity ensures proper lubrication of the turbochargers and internal components, which is critical for the engine's performance.
Why Capacity Matters for Performance
The 3.5 EcoBoost engine operates at high pressures and temperatures, making the right amount of oil non-negotiable. Overfilling the crankcase can lead to increased pressure within the valve cover, potentially causing leaks or seal failure. Conversely, underfilling the engine can result in inadequate lubrication, leading to increased friction and premature wear. Maintaining the 7.5-quart standard ensures the oil pump can circulate enough fluid to protect the engine under various driving conditions.
Oil Filter Considerations
When calculating the total oil capacity, the type of oil filter used plays a significant role. A standard filter holds a minimal amount of oil, but some high-efficiency or larger filters can hold up to a full quart of fluid. Therefore, if you are changing the oil filter yourself, it is wise to start by adding about 6 quarts to the engine, then install the new filter and top off slowly until reaching the full mark on the dipstick. This method prevents the common mistake of adding too much oil after the filter is installed.
Checking and Adding Oil
Regularly checking the oil level is just as important as knowing the total capacity. Owners should park the vehicle on a level surface, turn off the engine, and wait a few minutes for the oil to settle. The dipstick, usually located near the front of the engine, will provide an accurate reading. If a top-off is necessary after an oil change, adding small increments—roughly half a quart at a time—and rechecking the dipstick ensures you approach the correct level without the risk of overfilling.
Synthetic vs. Conventional Oil
The 2017 Explorer 3.5 performs exceptionally well with synthetic oil, which is often recommended by Ford for its superior thermal stability and resistance to breakdown. Synthetic oils typically have a more consistent viscosity, which is beneficial for the turbocharged engine. While the capacity remains the same at 7.5 quarts regardless of the oil type, choosing a high-quality synthetic blend can provide better protection and contribute to the overall efficiency of the powertrain.
Maintenance Schedule and Best Practices
Adhering to the maintenance schedule outlined in the owner’s manual is vital for the health of the 3.5 engine. This generally means an oil change every 7,500 to 10,000 miles for normal driving conditions. When performing this maintenance, using the correct capacity of oil and a high-quality filter is the foundation of the service. Proper disposal of the old oil and filter at a certified facility is also a responsible practice that ensures environmental safety.
