I don't have the numbers handy for diesels, but I'm reasonably confidant
that the percentage isn't a lot different even if the sources are different
(over rich areas in the fuel spray generate soot due to inadequate air and
some of the mixture around the fringe of the spray is too lean to burn).

The fact of the matter is that the moon landings are fake, the alien
autopsies are real, and the thousands of engineers that work for all the
auto companies all around the world (that look at fuel sprays and
combustions with lasers, high speed cameras, optically transparent engines
of all types, computer modeling, etc.) are completely unaware of potential
fuel consumption improvements like this one.


That's right! ;-)
And advanced concepts like vapor pressure (volatility) are just way out of
their league!

Of course, the vapor pressure of the fuel varies considerably with ambient
temperature, and the designers must optimize all of the fuel delivery and
mixing parameters for an average. Then the fuel product delivered is varied
throughout the year in places where wide seasonal variations could otherwise
make conditions far from the design datum. Perhaps it could happen that someone
in one such place has been able to achieve a slight improvement with a home
brew additive - he'll have to weigh the savings against the increased
maintenance costs in early replacement of all polymerized parts of his fuel
delivery system.
