I was just reading through the owners manual
for my 2002 BUICK.
It says "DO NOT USE ALCOHOL in the gas, will invalidate warranty"
( I don't have the book in front of me for "type of alcohol" )
Does this mean no can of "Dry-Gas" in wintertime ?
I know they use an ethanol mix in the gas
in some midwestern states....
How does this affect the warranty ?
Anyone had any experience with this ?
They have been putting that in Owner's Manuals for decades. Presumably it was
more common to find junk additives in gasoline years back. Now you would
probably only find it in third world countries.
So, where would I ever encounter METHANOL ?
( intentional, or accidentallly ? )
Methanol is sold as "gas line antifreeze". You dump a 12 ounce bottle of it
into a tank of gas. The alcohol combines with any water it finds, and then it
is burned in the engine. If the water is not trapped out that way, and if the
weather is very cold, it can freeze into ice and block the gas line completely.
So, if you don't need to use gas line antifreeze, then don't use it. The
methanol can have a softening effect on certain rubber and synthetic parts of
the fuel system, especially if used in higher concentrations than a bottle in a
Racetrack. There, methanol (wood alcohol) is used as a
high-performance fuel. Unfortunately, it can also dry out the rubber
parts of fuel systems, leading to leaks and ka-blooey. It also burns
with an ultraviolet flame, causing nearly invisible fires, which is
quite risky to emergency personell.
Ethanol will do the same thing, but usually on a smaller scale. Both
the US and Canadian governments allow ethanol (grain alcohol, or
booze) in concentrations up to 10%. This is called gasahol <sp>, and
most (for some reason Nissan seems to think that even this amount
voids warranties) auto manufacturers allow it.
OFF TOPIC DISCUSSION FOLLOWING
Why is ethanol used? For each energy unit, nearly two units are used
in production. I don't care how environmentally friendly it is, but
for me, that seems wasteful.
Quid quid latine dictum sit altum videtur.
(That which is said in Latin sounds profound.)
Because the American midwest produces
more corn than it can market.
Ag groups lobby the government to "do something with it".
They've developed home heaters that burn ( dried ) corn kernels.
Dump a bushel of corn in the hopper, and heat your home.
( my Gramma would say; "Burning FOOD ?? Blasphemy ! )
In the 1970's the British company that manufactures MG's discovered that
methanol (when combined with water) corroded the solder in their fuel
tanks causing them to leak. In the 1970's Atlantic Richfield added
methanol to its gas as an environmental move. Methanol's MSDS lists it
as a corrosive and it was not allowed inside of our plant for that
I would rather be exposed to the inconveniences attending too much
liberty than to those attending too small a degree of it.
