Frequently asked questions

Frequently Asked Questions

6 common questions answered

Is the oil filter replaced every time a 2018 Ford Flex has its oil changed?The manufacturer’s schedule calls for the 2018 Ford Flex oil filter to be replaced every 7,500 miles.

Replacing the filter with the oil keeps the new lubricant moving through a filter that can capture debris. A loaded filter can open its bypass valve, allowing oil to circulate unfiltered. The vehicle's service history and the manufacturer's schedule determine when the next replacement is due.

  • Filter replacement is paired with the oil service.
  • The filter holds debris carried by engine oil.
  • Book service at the published 7,500-mile interval.
What is included in an oil filter replacement on a 2018 Ford Flex?The service includes a filter matched to the engine, a new drain plug gasket or washer where applicable, and a leak check after the engine runs.

The filter is replaced alongside the oil rather than treated as a separate, unrelated task. The sealing surfaces are renewed as needed, and the finished installation is checked for leaks. David McDavid Ford can also help review the vehicle's maintenance history when you schedule service.

  • Engine-matched oil filter installation.
  • New drain plug gasket or washer when used.
  • Filter-seal inspection after the engine runs.
What happens if the oil filter on a 2018 Ford Flex is not replaced?A loaded filter can open its bypass valve, allowing oil to reach the engine without being filtered.

The engine still receives oil, but it stops receiving filtered oil, and that is a quieter problem than a complete loss of oil flow. Debris held by the filter can no longer be managed in the same way once the bypass valve opens. An inspection, the manufacturer's schedule, and the vehicle's service history help determine the appropriate next service.

  • Oil may circulate unfiltered through the engine.
  • An engine may sound noisier than usual.
  • Oil may darken quickly after a change.
Does a 2018 Ford Flex need a specific oil filter?Yes, the filter must be matched to the 2018 Ford Flex's 3.5-liter, 3,496 cc six-cylinder engine, and filters are not interchangeable across engines.

A correctly matched filter is selected for the engine actually fitted to the vehicle. That avoids treating every filter as a universal component and supports the filter's role in capturing debris from circulating oil. David McDavid Ford can identify the appropriate engine-matched filter during an oil service without relying on a part number in the booking conversation.

  • The engine is a 3.5-liter V6.
  • Displacement is 3,496 cc.
  • Filter selection follows the fitted engine.
Can the oil be changed on a 2018 Ford Flex without changing the filter?Oil can be changed as a separate action, but the manufacturer’s schedule calls for replacing the filter every 7,500 miles.

The filter collects debris from the oil, and stretching one filter across multiple oil changes can leave it carrying the previous service's contaminants. Once loaded, its bypass valve opens and unfiltered oil circulates. The appropriate service decision depends on the manufacturer's schedule and the vehicle's service history.

  • The filter captures debris carried by the oil.
  • A loaded filter may allow unfiltered oil flow.
  • Filter replacement is performed alongside the oil.
