How you think oil will 'absorb' air through an air tight bottle is beyond me.

The fully synthetic option Honda brought out is/was for their performance based engines. Think FN2R/FD2R/DC5R/S2000 - The Accord Euro is not a 'performance' engine but feel free to make reference to guys putting them in EG/EK's.

You also like to take things out perspective, I didn't say FEO oil was great/good - I said its OEM spec oil thats designed to last and it's proven that. Would I run my OEM Toyota oil in my car? No, I track/circuit work alot so obviously I'd use a better oil.

1wkw 'gain' can be from anything; temperature/day/air density. Obviously you knew that.
