In the ROW, yes. Even the same product sold under different names, LOL! For a while the European market had Mobil 1 New Life 0w-40 (same as our Euro 0w-40), Mobil 1 Turbo Diesel 0w-40 (same oil) and Mobil 1 ESP 0w-40.
Over here, we only had the one product, as the ESP 0w-40 wasn't sold in North America (and has never been on either the US or Canadian website).
Back in January IIRC, the PDS for ESP 0w-40 showed up on the US PDS search engine (though it still doesn't show up on the website) and the FS bottles began showing up in stores around the end of last year? In January the PDS for M1 0w-40 was pulled. More recently the website was updated to show the FS 0w-40 but there is still not a PDS for the FS 0w-40 shown on the US side.
However!
There is a Canadian PDS for the FS 0w-40:

Dated February, 2016.
And yes, there's been no clarification from Mobil on what the FS stands for though it is likely Full SAPS.
