I have horrible visions of all those nearly invisible metal filings, carbon
particles and other microscopic contaminants grinding away between the fuel
pump pistons and those finely precision holes to .0001" tolerances they
pump so carefully into. Combine the solid contaminants too small to filter
with all the acidic blowby chemistry, the reason we change the oil so often
in a diesel engine, and I'd think it wouldn't take long to simply eat away
at the inside of the amazingly-expensive injection pump, primary pump, and
the tiny nozzles' guts in the cylinders.

Yecch.....all for a few bucks saved on a tank? I suppose if we're going to
do this, we could also slowly dump the electrolyte from those old batteries
in the fuel tank, too, to eat away at it all quicker!


That is the central problem, I expect. One's lurid imagination about
graphic consequences. How did you feel when you first heard about
the new-fangled military technique for decoking gas turbines used in
helicopters - namely, throwing a basket full of chopped walnut shells
into the air intake?

Brian Whatcott Altus OK

Was used on lots of jet engines before helos.
