A friend has a 2010 F150 with the 5.4L engine. The manual says to use a Motorcraft FL820, not an FL820S, though. He said he cross-referenced the Purolator PureOne number to 24651, as did I. He said that the shop could not get either the 820S or the PureOne to screw on. He went and found a Mobil 1 M1-210 and it went right on?
Is there something missing?
