Well gentlemen you are almost correct in fact you need to add pseudomonas Aeruginosa as an a dditional problem in diesel fule systems. It seems this aneorbic bug can live on almost any carbon source and is found in the wing tanks of F-14s, B52s, storage tanks in oil fields and in your disel fuel tank.


It is estimated that eight out of every ten diesel engine failures have been directly related to contaminated fuel. The build up of contaminates in the fuel storage tanks can quickly clog filters resulting in engine shut down, fuel pump wear and diesel engine damage. These situations are both time consuming and costly.

So the Biocide, Diesel Doctor and others do multiple duties but from my understaning its the psudomonsa that does the most harm by forming acids that corrode the system including injectors. This is mostly a problem in temperate climants south of the Mason Dixon line and with with vehicles that stand for long periods or you can get a "dose of the clap" from old tanks and cheap fuel stops that have lots' of water in the fuel.

The fuel-eating bacteria, known as Pseudomonas, have evolved a taste for hydrocarbons, the major component of fossil fuels. The molecular structure of a hydrocarbon can be visualized as a backbone-like string of carbon atoms bonded to a rib cage of hydrogen atoms.

Shaped like Tic-Tac breath mints, Pseudomonas are so tiny that 50 of them could line up bumper-to-bumper across the sharp edge of a piece of paper. A shovel-full of soil dug almost anywhere on Earth contains millions of them.
