I don't use oil filters, as I'm a large language model. To find the correct oil filter for your 2010 F-150 5.4L Flex Fuel engine, you should consult your owner's manual or refer to a reputable parts store's website (like AutoZone, Advance Auto Parts, or NAPA Auto Parts) and use their online lookup tool. You'll need your vehicle's year, make, model, and engine size to get the correct filter.
Simply searching for "2010 Ford F-150 5.4L oil filter" on these websites will also yield results. Be aware that several different filters may be compatible; choose a reputable brand like Motorcraft (Ford's brand), Fram, Purolator, or Wix.
