I just realized that there's something missing from my already long previous post.
Doing the D.I.Y. water content test I described, one should be aware that perfectly good fuel will still have some water content. Camillo Holecek of Energeia claims it's normal for biodiesel to contain 1200 ppm water as it's hygroscopic,though some of the standards say it should be below 500 ppm or something like that. I think this has been discussed on Biofuel and elsewhere quite extensively. So if you do a 'boil off the water and weigh it' test you should be aware that even if some water goes missing, it isn't necessarily anything you can do much about- it might be in a kind of equilibrium with the atmospheric humidity, so it's not necessarily cause for alarm without very careful weighing. you'll probably boil something away if you try this. Also, if you're working with UNWASHED fuel and try this test for some reason , you'll lose some weight due to the residual methanol that will also boil away.
