Actually Minhea, small amounts of oil, even in vapor form, are enough to
make 
a difference.  In vapor form, it's now part of your 'Air' in the A/F ratio.

Given what I see in perfectly good CIS cars with wet oil PCV, I'm not with 
your conclusion.  Oil also tends to help exacerbate hotspots in the
combustion 
chamber.

Put another way, when you see perfectly good I5's at the track emptying a 
quart of oil from a catch can per day, where would that oil go without one?
Ever 
wonder why at track events, oil consumption reaches extremely high levels in

a perfectly normal S car?  I don't.  I might add that reducing the aeration
of 
the oil is key as well (read:  Big oil coolers = good).  For more on this

Scott-  

For the ignorant (me mostly) what then are the options, both DIY (read:
cheap) and aftermarket to go with a catch can, filter, etc. system?  Mine
gets a 'good running' pretty much every day, 20+k/yr., and I eat about a
quart every 1-2k, doesn't seem to be rings / valve guides.  Would like to
alleviate this, your thinking sounds sensible.  

Curious, thanks.
