<VV> Opinions on Old Gas

[ChiefTAM at aol.com]

What is the prevailing thought on old gas, using it or getting rid of  it?
 
I have some gas that was in my ATV for over a year, that caused the needle  
and seat to gum up.  I drained that out and replaced it with fresh for my  
hunting trip this year, but now have the old gas.  As this is only a year  or so 
old, I thought about dumping it a couple gallons at a time in the wife's  2005 
RAV4 four banger.  Thoughts?
 
I am just about ready to fire up the 69 Monza Convertible after rebuilding  
the engine.  The last thing to do is to drain the tank and put in some  fresh 
gas there as well.  The engine starting missing in April of 2004 when  my 
brother was driving it from Minnesota to Texas.  I fixed the ring  problem in July 
or August of 2004, and ran the car about 60 miles before a bad  bearing took 
out the engine.  So, the gas in the tank is probably about 2  years and 7 
months old, maybe a few months less.  Any thoughts about this  (93 octane then) 
gas?  Would this be safe to mix in a few gallons at a time  in the wife's Toyota? 
 If not, any recommendations on how to dispose of old  gas?  Thanks.
