What kind of oil does a 2016 Ford Flex take?

The 2016 Ford Flex generally uses 5W-20 full-synthetic motor oil that meets Ford specification WSS-M2C946-A (or newer).


Because the Flex offered two V6 options (the standard 3.5L Ti-VCT V6 and, in some trims, an EcoBoost variant), it’s important to verify the exact requirement for your engine and region in the owner’s manual or with a Ford dealer.


Oil type and specification


For most 2016 Flex models, the recommended oil is 5W-20 full synthetic motor oil. Using oil that meets Ford’s specification helps ensure proper lubrication, fuel economy, and warranty compliance.


About the engine and conditions


The information above primarily applies to the common 3.5L V6 engine found in many 2016 Flex models. If your Flex has a different engine option or you operate in extreme climates or have heavy towing needs, check the owner’s manual for any exceptions or approvals.


Key considerations when selecting oil:



  • Use 5W-20 full-synthetic motor oil that meets Ford WSS-M2C946-A (or newer) specification.

  • Choose the correct oil filter and replace it at every oil change; avoid mixing brands.

  • Adhere to the maintenance schedule and oil-change intervals as specified in the owner’s manual; synthetic oils typically allow longer intervals than conventional oils, depending on driving conditions.

  • Follow any climate- or usage-specific recommendations in your manual, especially if operating in extreme temperatures or under heavy load.


Always confirm the exact specification in your owner’s manual or with a Ford service advisor, particularly if your Flex has the EcoBoost engine or you’re in extreme conditions. Using the right oil helps maintain engine health and warranty coverage.


Summary


The 2016 Ford Flex typically takes 5W-20 full-synthetic motor oil that meets Ford specification WSS-M2C946-A or newer. Verify the exact requirement for your engine in the owner’s manual, and follow the recommended oil-change intervals and filter guidelines to keep your engine running smoothly.

Can I use 5W-30 instead of 5W20 in my Ford Escape?


Oil viscosity is only really relevant when you're under manufacturer's warranty. After warranty you can use whatever you want. I have a 2017 which calls for 5W20, but I use 5W30.



How many quarts of oil does a Ford Flex use?


The Ford Flex oil capacity is generally 6 quarts of oil for the 3.5L non-turbo engine, but it can vary slightly depending on the year and if it's a turbo model. For the turbo model, the capacity is 5.7 liters, which is about 6.0 quarts. It's best to always check your owner's manual for the most accurate information for your specific vehicle. 

  • 3.5L non-turbo engine: 6 quarts (with filter) 
  • 3.5L turbo engine: 5.7 liters (approximately 6 quarts) with filter 
  • For all models: Always confirm the exact capacity in your owner's manual. 



What kind of oil goes in a Ford Flex?


The Ford Flex oil type is generally 5W-20 or 5W-30, depending on the model year and specific engine. For colder climates, some models may require 0W-30 oil, and it's crucial to check your owner's manual for the exact recommendation and any specific certifications (like WSS-M2C961-A1). The oil capacity is typically 6 quarts, but this can vary by model, so always check your manual before changing the oil.

  • Capacity: The typical capacity is 6 quarts, but confirm with your owner's manual for your specific model. 

How to determine the correct oil
  1. Consult your owner's manual: This is the most reliable source for your vehicle's specific needs. 
  2. Check the oil cap: The correct viscosity is often printed on the oil filler cap. 
  3. Consider your climate: The viscosity recommended for your vehicle may change based on your local temperature range.
