While that may be true, I add Sta-Bil + isopropyl  alcohol to a full tank of 
FRESH gas every fall and run the engine a bit to  get it into the pump, fuel 
line and carb before shutting down for the long,  cold, salted-roads winter.  
Then in the Spring, after at least 3 clean  rains have washed away all the 
salt, I restart the engine after building up oil  pressure enough to put out the 
oil pressure light.  If I don't use up all  the gas during the warm weather, I 
siphon out what's left and put it into my  winter cars.  Then I refill the 
Corvair tank with FRESH gas adding Sta-Bil  and isopropyl alcohol for another 
winter.  Some of this treated gas ends up  in my lawnmower as well to protect it 
for the winter..
    The Sta-Bil extends the life of the  gasoline delaying normal degradation 
and gumming.  The isopropyl  alcohol co-dissolves the water condensate and 
gasoline to a homogeneous  mixture.  Unlike more recent cars, the Corvair tank 
is open to the  atmosphere through the vented gas cap so it "breathes" 
surrounding air (and  moisture) in and out due to the change in temperature from day 
to  night.  Moisture in this air will often condense and end up as insoluble  
drops of water under the fuel (water is heavier than gasoline) in direct  
contact with the floor of the gas tank.  Over time, it can rust holes  through the 
tank resulting in leakage.  (Just ask me how I know  this.<GGG>)  The 
isopropyl alcohol ("Iso-Dri Gas") keeps the  condensate in suspension out of direct 
contact with the metal gas tank.
