FW: <VV> Gas Tank

[FrankCB at aol.com]

Guy,
    You're right, I should have done that so this is  going to V V as well as 
to you.
    Besides adding the iso propyl alcohol don't forget  to add some "Stabil" 
to help keep the gasoline itself from deteriorating.   I just drained out last 
year's gas (went into my MiniVan) and will add fresh gas  plus Stabil plus 
isopropyl alcohol.  Then I'll run the engine and drive the  car a bit to get all 
the fresh gas (with additives) into the fuel pump,  carb and gas lines.
    I consider it insurance to prevent having to  replace the gas tank and 
clear out clogged lines and carb.

Hi  Frank, 
I will heed your  advise,  I had stopped using “dry gas”  when ethanol came 
out assuming that it had the same water absorbing  properties.  I get in 
trouble with  that word “assume”.  You may very  well have saved me a gas tank as 
in the  Chicago area my car sits for  long periods at a time due to the VERY 
heavy salt use.  I think you should put your response  to all on VV.  Thanks.

Guy,
 
While it  is quite true that many locations (including northern NJ) now have 
10%  ethanol in the gas, I don't believe that fact eliminates the necessity of 
 adding isopropanol (isopropyl alcohol) periodically to the gas tank to keep  
water from coming out of solution and falling to the bottom of the tank to  
start forming rust.  First, it's very expensive in producing ethanol to  remove 
the water much below the 10% level.  Anhydrous ethanol, while  possible, is 
unlikely to be the quality of the ethanol actually mixed  with the gasoline.  
Second, pure alcohol is quite hygroscopic which  means it will readily absorb 
water from the air or from the storage tank or  piping through which it moves.  
So I consider the periodic addition of  isopropanol to be like insurance.  If 
it keeps from having to replace  another fuel tank and contents, it's well 
worth the  expense.
 
I  would also recommend that an infrequently used Corvair should have its gas 
 tank kept as full as possible.  That minimizes the amount of moist air  
above the gas level in the tank so there is less moisture to condense out and  
fall into the gas.

Hi  all,

In many states the fuel already has ethanol added and if so  you
shouldn't have to add dry gas.  If I'm mistaken on this please  let me
know.
