I don't know what was in my 011 EL when I bought it a few years back (with 67K on it), but 5 days later, I took it to my local trusted shop & told them to use the Castrol GTX Premium Full Synthetic & Motocraft filter (which is what the owners manual states too) that I get from da Zon, and I have been getting it changed every 5-7K miles since then with zero issues
I also change my own Air & cabin filters, so no worries there, but if I was physically able to, I would do the oil changes myself, but unfortunately, that ship has sailed a while ago...
And just an FYI, my mechanic mentioned the 1st time that once you go FS, you can't switch back to blend or regular, due to the differences in the compounds that make up the different types which aren't compatible with each other... so I called 2 different Ford dealerships & they said the same thing....
