Owners of a 2017 Ford Explorer understand that maintaining this capable three-row SUV requires attention to the specific fluids recommended by the manufacturer. The type of oil used in the 3.5L EcoBoost engine is not just a detail; it is a critical component that ensures optimal performance, efficiency, and longevity. Using the correct viscosity and meeting the necessary specifications is essential for the turbocharged engine to operate smoothly under various driving conditions.
Recommended Oil Specifications
For the 2017 Ford Explorer equipped with the 3.5L EcoBoost engine, Ford specifies the use of a 5W-20 viscosity oil. This specific grade is engineered to provide the right balance of protection and fuel efficiency. It is crucial to adhere to this recommendation, as using a thicker oil can lead to decreased fuel economy and reduced engine performance, while a thinner oil might not provide adequate lubrication under high stress.
API Service Standards
Beyond the viscosity rating, the oil must meet specific performance standards set by the American Petroleum Institute. The 2017 Explorer requires oil that is certified to the API SN PLUS specification. This standard ensures the oil provides enhanced protection against low-speed pre-ignition (LSPI), a condition particularly relevant to turbocharged direct-injection engines. Using an older API SN rated oil might not offer sufficient defense against this issue.
Synthetic vs. Conventional Oil
While the factory fill is typically a full synthetic blend, owners have the flexibility to choose between synthetic and conventional oils during maintenance. A full synthetic 5W-20 is generally the preferred choice because it offers superior performance in extreme temperatures, better resistance to breakdown, and improved protection for the turbocharger. However, a high-quality conventional oil that meets the SN PLUS standard is acceptable for normal driving conditions and less demanding usage patterns.
Benefits of Synthetic Oil
Enhanced protection in cold starts, reducing wear on critical engine components.
Superior performance at high temperatures, maintaining viscosity and oil pressure.
Longer change intervals, often extending up to 10,000 miles depending on driving habits.
Improved fuel economy due to reduced internal friction.
Oil Capacity and Filter
When performing an oil change, it is important to know the correct capacity for the 3.5L EcoBoost engine. The system typically holds around 6 quarts of oil, but it is always best to consult the vehicle’s manual for the exact specification. Additionally, installing a high-quality oil filter that meets or exceeds OEM standards is vital. The filter traps contaminants and debris, preventing them from circulating through the engine and causing premature wear.
Maintenance Schedule and Severe Conditions
Ford recommends changing the oil and oil filter at least once every 12 months or 7,500 miles for normal driving. However, if the vehicle is subjected to severe conditions, this interval should be shortened to 6,500 miles or 6 months. Severe conditions include frequent short trips, stop-and-go traffic, towing a trailer, or driving in dusty environments. Adhering to this schedule is critical for the long-term reliability of the engine.
Checking Oil Levels
Regularly monitoring the oil level between changes is a simple yet effective way to prevent engine damage. Owners should check the dipstick at least once a month, ensuring the vehicle is on a level surface with the engine off. If the level is low, add the recommended 5W-20 oil incrementally and recheck to avoid overfilling. Observing the color and consistency of the oil can also provide early signs that an oil change is due.
