water in fuel
i've been on several forums researching bio-d and wvo, as well as diesels in general. and while there's a universal concensus that water in the fuel is BAD. no one so far has said how much water is bad.

now i'm not talking about what i call "gross water" ie visible droplets of water but the miniscule kind you can't see.

so i took advantage of some resources that are available to me. i work at a chemical plant.

i gave some samples to one of the analytical chemist here. testing for water is a routine part of our qa program.

all tests were done by a PhD Anylitical Chemist here at work.

the results are as follows:

D#2 from hess truck stop on rt13 0.7068%

k-1 from sothern on rt10 0.7883%

bd100 unwashed and settled 0.29%

settled and filtered WVO 0.28%

wvo un filterd fresh from fryer 0.32%

i was actually surprised by the results, and i'm going to resample in a week from the same sources and see if there's a difference.

but this leads to my question; so how much water is too much?? is there a spec from MB on % water allowable in fuel?

thanks.
