The 2020 Explorer ST uses 5W-30 full-synthetic motor oil that meets Ford’s WSS-M2C946-A specification, with a total capacity of about 5.7 quarts including the filter. Always verify the exact requirement on the oil fill cap or in the owner’s manual.
Understanding the requirement
The Explorer ST is powered by a 3.0-liter EcoBoost V6, a high-performance engine that relies on synthetic oil designed to handle turbocharged operation. Ford specifies a viscosity of 5W-30 and requires the oil to meet their WSS-M2C946-A standard (or the current equivalent Ford specification). Using oil that does not meet this standard can affect engine performance and may impact warranty coverage.
Climate, driving style, and severe-service conditions can influence the best viscosity choice, so consult the owner’s manual or your dealer for the exact specification for your vehicle’s build and region.
Key oil facts for the Explorer ST:
- Viscosity: 5W-30
- Type: Full synthetic motor oil
- Ford specification: WSS-M2C946-A (or equivalent current Ford spec)
- Capacity: Approximately 5.7 quarts with filter
Following these guidelines helps ensure proper lubrication, performance, and warranty considerations for the SUV’s turbocharged powertrain.
Where to verify and how to service
To be certain you’re using the correct oil, check the engine oil fill cap for the exact specification, review the owner’s manual, or contact a Ford dealer. When changing the oil, replace the oil filter and use an oil that meets the Ford specification. If you’re unsure, choose a reputable 5W-30 full-synthetic oil that clearly carries the Ford WSS-M2C946-A specification or the current equivalent.
