I'm am pleased you have had good luck with your engines over the past decades. Regarding the addition of fluids to your diesel fuel, you can certainly add anything you want into it,as it truly is your choice. I have no problem with your practice, as it will not affect me in any way. We are both allowed to have our own opinions, (according to the rules of the forums), and at the end of the day, we can agree to disagree and go our own ways, still members of the greatest place to get information and discuss our love for Cummins Turbo Diesels, the TDR.
In the previous post, I was stating my opinion based on my experience and my knowledge. After reading your reply, and seeing that you made light of it, I should clear up any misconceptions you may have about my opinon stated in that post.
When it comes to adding something in my diesel fuel, I have and will continue to contact the folks who manufacture fuel systems, who do research day in and day out, and scientifically document their findings. Having been a certified diesel fuel injection technician by the ADS, (Association of Diesel Specialists) and worked in the diesel fuel injection industry since 1971, from out in the field, to managing a shop, to managing parts, and even training folks to remanufacture diesel fuel injection components, I am somewhat aware of the problems that have occurred over the years from the use of non-approved fluids in diesel fuel. I have seen the coked injection nozzles, split injector nozzles, stuck nozzles, worn out plungers and barrels, advance mechanism failures, locked head & rotors, etc. Some of these failures resulted from the addition of many different fluids that were either high in ash content or were high on the solvent scale causing lack of lubrication. Most of these failures did not immediately occur after adding these fluids, but became problems that slowly built up over time to eventually become failures. Working for a company that has been factory authorized for service and warranty repairs, has technicians trained and authorized by the major manufacturers of diesel fuel injection equipment and further certified by the ADS, we have direct contact with the factories: Bosch, Stanadyne, Delphi, Zexel, Alliant, Siemens, Nippondenso, etc. I have never seen a bulletin from even one factory that recommends the addition of automatic transmission fluid, power steering fluid, or 2-stroke engine oil to diesel fuel. I do remember General Motors at one time recommending putting 5 gallons of unleaded gasoline into a 25 gallon tank of diesel fuel, and that was rescinded after disastrous results were experienced.
In science, theories are never hunches, feelings, or guesses. Science is not about belief—it is about making inferences based on evidence. A theory is an explanation of the general principles of certain phenomena with considerable facts to support it. A fact is an indisputable truth. Manufacturers know the fact that ash will coke an injection nozzle and cause failure, and the fact that ATF was not intended to be burned. The theory is then that these fluids should not be added to diesel fuel because of known facts. Scientific testing then could continue to prove the theory by experimenting with differing percentages of these fluids added to fuel and running engines with the mixtures over time at differing loads in controlled conditions and documenting the results.
Based upon these known facts and my experience in seeing the results of other's experiments with different additions to their diesel fuel, I base my honest opinion. It is offered only upon that basis. If you find it humorous, then so be it. If you find it enlightening and can benefit from someone else's experience, then so be it also.
I wish you the best of luck...
