How much oil does a 2017 Ford Flex 3.7 take?
There is no 3.7-liter option in the 2017 Ford Flex; that year’s Flex uses a 3.5-liter Ti-VCT V6. The engine oil capacity for that configuration is 6 quarts with a filter. If you’re looking at older Flex models that did use a 3.7L Duratec, their capacity is typically around 5 quarts with a filter. Always verify the exact figure for your VIN in the owner's manual or on the oil-fill cap, and use the recommended oil grade, usually 5W-20 synthetic.
Engine options and oil capacity for the 2017 Ford Flex
The 2017 Flex lineup did not officially offer a 3.7L engine. Most models were equipped with the 3.5L Ti-VCT V6, which determines the oil capacity. Below is a quick guide to the relevant capacities you might encounter with Flex engines across years.
Here is a quick overview of oil capacities by the engine variants you might encounter in a Flex, noting that the 3.7L is not standard for 2017.
- 3.5L Ti-VCT V6 (the typical 2017 Flex engine): 6 quarts of engine oil with a filter; recommended oil grade is 5W-20 synthetic.
- 3.7L Duratec V6 (older Flex or non-2017 configurations): about 5 quarts of engine oil with a filter; recommended oil grade commonly 5W-20, with climate-dependent adjustments.
Bottom line: For a 2017 Flex with the standard 3.5L engine, plan on about 6 quarts of oil when changing the oil and replacing the filter. Confirm with the owner’s manual or the oil-fill cap to be certain, and use the recommended 5W-20 synthetic oil.
How to confirm your exact oil capacity for your vehicle
Since engines and configurations can vary by VIN, the safest approach is to:
- Check the owner's manual for the specified oil capacity and grade for your exact trim and drivetrain.
- Inspect the oil-fill cap or the under-hood label, which often lists capacity and oil type.
- Consult the Ford owner portal or dealership service guidance if you’re unsure.
- After an oil change, recheck the dipstick to ensure the oil is within the proper range.
If you plan to perform an oil change yourself, ensure you have the correct filter, the right grade of oil, a drain pan, gloves, and a proper jack or ramps. Always dispose of used oil at an approved recycling facility.
