just use some 2 stroke oil like stated. If you plan on leaving your engine sit for a while use appropiate fogging oil.

it isnt really rocket science.... or is it?

you want something that will either protect (if you are storing) or to create a seal (if it is washed down or sat for along time) so theny uo want something that will burn off somewhat easily, will not harm o-rings/rubber pieces and will coat all moving pieces.

Water is a very good solvent, dissolving many types of substances. The substances that will mix well and dissolve in water (e.g. salts) are known as "hydrophilic" (water-loving) substances, and those that do not mix well with water (e.g. fats and oils), are known as "hydrophobic" (water-fearing) substances. The ability of a substance to dissolve in water is determined by whether or not the substance can match or better the strong attractive forces that water molecules generate between themselves. If the ability of a substance to dissolve in water cannot, the molecules are "pushed out" from amongst the water and do not dissolve.

-----------------------------------------------------------------------------------------------

Water is called the "universal solvent" because it dissolves more substances than any other liquid.

------------------------------------------------------------------------------------------------

so water isn't corrosive ehh?

furthermore:

--------------------------------------------------------------------------------------------------------------------
Water (H2O) can dissolve more substances than any other solvent
(including acids), so it is called the universal solvent. It is so good at
dissolving many different substances for two reasons:

1. Water is a non-ionic, polar molecule. ("Non-ionic" means that it does
not have an overall charge, and "polar" means that there is a charge
difference throughout the molecule.) In a water molecule, the oxygen atom
has a slight negative charge, whereas the hydrogen atoms each have a slight
positive charge.
H
/
(-) O (+)
\
H

Since "like dissolves like", water will dissolve other polar, non-ionic
substances, such as sugar. In this case, water does not change the
chemical structure of the molecule at all.

Furthermore, the slight charges enable water molecules to attract to (and
therefore dissolve) both positively and negatively charged substances, such
as the sodium and chloride ions that make up table salt. Here, the salt
molecule actually dissociates into the two ions that make it up. (Water
will not dissolve olive oil, because olive oil is a non-polar, non-ionic
substance.)

2. Water can hydrogen bond. Hydrogen bonds are weak bonds that form between
a hydrogen atom and an oxygen, nitrogen, or fluorine atom. The hydrogen
must already be covalently bound to O, N, or F, so that the hydrogen ends
up being sandwiched between two of the other atoms. Here is a very rough
illustration of hydrogen bonding among water molecules:

H-O-H H
: |
H-O-H..O-H..O-H
|
H

The dashes (-) represent covalent bonds between atoms, whereas the dots
(..) represent hydrogen bonds between atoms. Covalent bonds are strong
bonds that hold atoms together within molecules, whereas hydrogen bonds are
much weaker bonds that hold atoms together between molecules. (By the way,
the angle in a water molecule is actually about 104.5 degrees, not 180
degrees or 90 degrees as I've shown in this illustration.)


Some acids might dissolve many substances, but there aren't any acids that
dissolve as many substances as water. Plus, acids will react chemically
with substances, thereby changing them into different species rather than
simply dissolving them.


Complicated, eh? You might want to check out a general chemistry textbook
in order to learn more about this (you might get some more helpful
pictures!). I hope that this explanation helps you out, though.

^there is a nice 7th grade level explanation i found.

oh and btw, here is seal compatability guide for ATF

drago86

Oh, and here are the MSDS's you asked for,..

http://www.texacoxpresslube.com/imag...trans_atf3.pdf

note that they show a ~4% solvent content.

I was under the impression that water could act as both acid and base, when Hydrogen is seperated from water the remaining OH- group is basic, remember that H20 and OH- are indeed a conjugate acid-base pair, each resulting from the addition or removal of a proton(H+). Acids and bases, both have the capacity to degrade substances.

thats interesting, maybe i should invest in some teflon seals


what i get from this argument is that i will not use ATF on the grounds that there is a possibility that it will harm the engine and since two stroke oil is just as effective, ill use that instead

Thanks... I think... I am assuming that you are agreeing with me; that water is a corrosive chemical.... And whatever 7th grader wrote that should be moved up a few years... LOL... j/k...

Thanks... I really needed one of these charts... It will definatley come in handy...

That is what I get out of it too... Only keep in mind it is bad for the cats to add anything extra to the combustion chamber if you do not have to...

Next week I am going to ask if I should let half of the air out of my tires and see what happens to that thread...
