Owners of the 2017 Ford Explorer rely on the 3.5-liter EcoBoost engine to deliver a blend of capability and comfort that defines the mid-size SUV segment. Understanding the specific oil requirements for this twin-turbocharged powerplant is essential for maintaining peak performance, ensuring longevity, and preserving the warranty coverage on this significant investment.
The 3.5L EcoBoost Engine Specification
The heart of the 2017 Ford Explorer is its 3.5L Ti-VCT V6, which produces 365 horsepower and 350 lb-ft of torque. This robust output places considerable demand on the lubrication system, making the choice of oil far more critical than for standard naturally aspirated engines. The system utilizes a turbocharger to force extra air into the combustion chamber, which in turn generates higher temperatures and stresses on the oil.
Ford's Official Motor Oil Recommendation
Ford Motor Company provides specific fill specifications to ensure optimal protection for the EcoBoost engine. For the 2017 Explorer with the 3.5L engine, the factory fill requires 0W-20 synthetic motor oil. This low-viscosity formula is designed to improve fuel economy while providing adequate lubrication during cold starts and high-temperature operation.
Why 0W-20 Viscosity Matters
The "0W" rating indicates the oil's flow characteristics at extremely low temperatures, typically down to -40°F, ensuring the engine is protected the moment you turn the key. The "20" refers to the oil's thickness at operating temperature. Ford engineered this specific viscosity to reduce friction, which directly translates to better fuel efficiency and reduced wear on the precision-machined internals of the EcoBoost engine.
Synthetic Blend vs. Full Synthetic
While the factory recommendation is for a full synthetic 0W-20, some drivers consider alternatives. It is strongly advised to adhere strictly to the full synthetic requirement. The turbocharged nature of the 3.5L engine generates significant heat, and only a full synthetic can maintain its viscosity and protective additives under these demanding conditions. Using a lesser grade can lead to premature oil breakdown and potential engine damage.
Critical Specifications and Additives
Beyond the viscosity grade, the oil must meet specific Ford performance standards to protect the advanced components of the 2017 Explorer. Look for the following certifications on the oil container:
Ford WSS-M2C947-B
API SN or the newer API SP rating
ILSAC GF-5 or GF-6 specification
These certifications confirm that the oil contains the necessary detergents and dispersants to handle the byproducts of the EcoBoost combustion cycle, preventing sludge buildup and keeping the turbocharger operating efficiently.
The Role of the Oil Filter
Selecting the correct oil is only half the battle; the filter must be equally capable of trapping contaminants generated by the high-output engine. The 2017 Explorer requires a filter with a high dirt-holding capacity and a robust anti-drain-back valve. Using the genuine Ford oil filter or a premium aftermarket brand ensures the full synthetic oil is not contaminated, allowing it to flow freely and do its job effectively.
Maintenance Schedule and Best Practices
Even with the superior resistance of synthetic oil, regular changes are non-negotiable. Ford recommends an oil change interval of 7,500 to 10,000 miles under normal driving conditions. However, owners who frequently tow, drive in stop-and-go traffic, or operate in extreme climates should adhere to the shorter end of that spectrum. Always reset the maintenance reminder system after each oil change to ensure the vehicle's computer accurately tracks the service intervals.
