I stumbled upon the Eneos web site the other day. On it, is a bar graph, touting the coefficient advantages of Eneos 0W20 relative to other synthetic 0W20 oils (including Mobil 1). With Eneos being the "oil of choice" (when cost is no object), of many Toyota and Honda owners (especially hybirds) - what do you think of this? If this link does not work, someone else please make the attachment for me.

Questions:
1) Is a low coefficient of friction in a motor oil, a bigger factor to mpg gains than A) a low cst@40C and 100C numbers or )B a low HT/HS?
2) Is low engine wear a a result with a low coefficient of friction?
3) Is this all just an exercise in marketing and academic nonsense?
Currently using Amsoil 0W20 in a 2010 Ford Focus, while getting up to 35 mpg on the highway. On a side note, I find it mildly amusing that many Honda and Toyota owners first reach for Motorcraft 5W20 (a Ford spec oil), when given a choice. I have a stockpile of the recently clearanced Motorcraft 5W20 FULL Synthetic ready to "report for duty" when this Amsoil runs out. Paid $2.00/qt this past summer at Advanced Auto Parts.
