Why 5W-20 matters for this engine
The 3.5 EcoBoost is a turbocharged V6, which benefits from a lighter, high-quality oil that lubricates quickly on cold starts and maintains stability under higher temperatures. A 5W-20 full synthetic offers better flow at startup, reduced engine wear, and improved overall protection during turbo operation compared with heavier grades.
Climate and driving considerations
In extreme heat, heavy towing, or severe driving conditions, always verify the correct specification in your owner's manual or on the vehicle’s information placard. Some operating environments may have additional recommendations or reminders to follow the standard 5W-20 requirement.
Oil change and maintenance tips
Keeping up with oil changes and using the right filter is crucial for turbocharged performance. The guidance below helps ensure you stay on track with a 2017 3.5 EcoBoost.
- Install a new oil filter rated for the engine and torque it to spec
- Use a fresh batch of 5W-20 full synthetic oil
- Fill to the full mark on the dipstick after a brief engine run to circulate oil, then recheck level
- Dispose of used oil and filter according to local regulations
Before listing the practical steps, here is a concise maintenance checklist for oil changes:
In practice, follow your owner's manual for the exact change interval and any climate-specific advisories. Synthetic 5W-20 generally allows longer intervals under normal driving than conventional oils, but conditions such as frequent short trips or towing can shorten the interval.
Where to buy and how to verify compatibility
For the best results, choose a reputable brand that clearly lists 5W-20 full synthetic and carries the appropriate API/ILSAC certification. Ford’s own Motorcraft line is the most straightforward option, but many third-party brands also meet the required standards when labeled as 5W-20 full synthetic.
Summary
The 2017 Ford 3.5 EcoBoost engine is designed to run on SAE 5W-20 full synthetic motor oil, with an approximate capacity of 6 quarts (6.0 quarts with filter). For reliability and turbocharged protection, use Ford Motorcraft 5W-20 Full Synthetic or an equivalent that meets current API/SN and ILSAC GF-5 standards, and always confirm specifics in your vehicle’s manual or placard. Regular oil changes using the correct oil help maintain performance and longevity of this turbocharged V6.
