Yeah I was disappointed that they didn't show the Purolator PureOne as well. I like the Mobil 1 / K&N filters too. They tend to have the highest multi-pass efficiency rating for a 30 micron particle. Of course I don't know that there is any way to compare them without sending off a sample for actual oil analysis. It does give you a good idea of build quality though.
It is probably because Purolator is the one who makes the Motorcraft filter, well according to the internet (and we all know how reliable that is). The only difference from everything I have read is the filter media in the PureOne has a better micron rating.
