Does oil have a "sell by" date

[Steve]

Just wondering does oil that has been stored in the garage for a year have a sell by date?

[JPM]

Doubt it, it's been under the ground for a couple of million/billion years in it's raw state

[Steve]

couldn't exactly put that straight in the bike

Does it not absorb moisture the same way as hydrobolic fluid.

Re:under ground for millions of years:
bottled spring water - millions of years old rain soaked through volcanic rock, kept flowing in deep subterranean streams and lakes for eons....best before September 2005. What's all that about then?

I'd hope that fully synthetic oil HASN'T been under the ground at all!

Actually, the question made me go and try to find out exactly what synthetic oil is. Difficult to get answers of course, because the recipe will be a trade secret (of many different companies). Basically, it seems it is highly refined and "constructed" so that anything in it benefits the engine and the lubricating/protecting process. Mineral oil apparently has many components that are actually HARMFUL to your engine (doesn't mean you shouldn't USE it of course)
