FE must be something like "Fuel Efficiency".

I would have thought the same thing. But the BITOG guys (who research and debate oil all day long apparently) swear that the N20 was added to both the LL01 and the LL14 test spec; something about the N20's direct injection engine needing an additive to keep soot/carbon off the exhaust valves/stems. I'll do some additional research and see what I can dig up.
