Default Changed my mind about fuel polishing

"The diesel and water don't mix"
NOT so.

Water to a small amount dissolves in diesel
Diesel to a small amount dissolves in water
Emulsions are formed between the two phases of oil and water ... and
disperse throughout the oil

Only FREE water doesnt mix with water as it has gravimetrically
settled out of the oil due to gravity.


THREE phases of water in oil: Free water, dissolved water, emulsified
water.



Some amount of my skin molecules become part of my computer keyboard and vis
versa. This is meaningless in the scheme of things for both me, my keyboard,
and for diesel/water in a tank. If it wasn't meaningless, the engine would
quit or wouldn't run to begin with. This doesn't happen unless the fuel is
contaminated (and the amount of water you describe clearly isn't enough in
most situations), the engine can't get enough air, or the fuel filter/line
is clogged. If you want to further limit the emulsification, then limit the
sloshing, which is exactly what a full or near full tank will do.

I stand by my original statement for real-world, sailboat applications.
