Left: Fig 2 - Filter similar to that shown in Fig 1, left in jar filled with ULSD addition of an occasional
few drops of water for an additional year. This shows that sludge is a living, growing mass, and not
caused by fuel instability (The ULSD used was extremely stable.)
Above: Fig 3 - Fouled fuel filters removed from an auxiliary diesel generator on board a naval vessel. Fouling of paper
filters requires much less physical buildup of sludge than on felt filters as shown in Fig 1.

Over the past twenty years we have
refined this chemistry, tested, tweaked the
formula, and re-tested—and have earned
the trust of major users. This dual filming
amine chemistry is now used by homeown-

operators, tug boat companies, standby
generators, navies and coast guards around
the world—in short, all those who use No.

Bob Tatnall spent thirty years as a materials engineer with
DuPont, specializing in corrosion, linings and coatings. In 1968
he first observed a little-known phenomenon called microbiologically influenced corrosion, or MIC. Fascinated by this destruction
of metals and alloys by bacteria, Tatnall spent the rest of his
DuPont career learning about how bacteria and other microorganisms interact in different environments. In 1991, he retired from
DuPont and became a biocorrosion consultant and developed the
sludge-control additives that led to his forming the fuel treatment
company Fuel Right.
