Both Primrose and FPPF emulsify.
I run the FPPF, always have, and will continue to do so. I've seen the sample vials (have the kit) with emulsified water in fuel at several years old along with untreated fuel turning brown in the same type of vial. I've also seen the demo where the competitive product makes jelly fish, fisheggs, or chickenbroth depending on the makeup...
John,
I have been too the fppf website and seen the demonstration,
http://www.fppf.com/pDemoWtrDsprtnHB.html
It's easy to look at this demo and say to yourself "It's clear now, that's great because the water has "disappeared" and now it will no longer be a problem" But the water is still there and the problem is that water in emulsion will wear and damage the injectors just as well as free water in a 24,000 psi fuel injection system.
From a discussion I had with a Shell engineer concerning their rotella DFA additive (which disperses minute amounts of water, but demulsifies larger amounts)...
"Free water, or water/fuel emulsion delivered to an injector, can be a disaster. Water is instantly turned to steam with sufficient force to destroy injector tips. Not only is the injector ruined, but metal debris enters the combustion chamber where it can damage pistons and liners, as well as turbocharger fins."
On the issue of corrosion and not wanting to have free water settling, etc...
"ROTELLA DFA contains corrosion inhibitors that reduce corrosion on steel surfaces, thus protecting tank, lines, and other steel surfaces when water is present."
Stanadyne also incorporates a corrosion inhibitor.
Both you and George at avlube have encouraged the use of an emulsifying additive (both here and on that "other diesel site" too). Both of you market, sell and profit from the sale of these products. Both of you sell them and recommend them without warning user's of the risk they are taking on.
Both you and George are highly respected on this board and now those who respect your opinion now recommend it to everyone else without qualification.
GM states that one shouldn't use an emulsifying additive. Maybe if they would have went into more detail as to why with graphic photos of mangled injectors, then maybe things would be different here. Instead, it seems to always turn into a "bud versus coors argument".
So fppf has always worked great for you - that's great. Unfortunately, you are "statistically insignificant" and so am I. Out of the tens of thousands of trucks out there, will using an emulsifying additive contribute to the premature wear and failure of one injector? Five? a hundred? How much water are you going to get in your fuel one day?
Neither you nor I have the qualifications or statistical data to definitively answer, but the one thing I hope we can both agree on is that it is greater than zero. You know that someone is going to pull up to a station and get the bottom of the tank somewhere in the u.s. this year; So maybe that poor soul bought fppf from you and is now out of warranty; Maybe if he wouldn't have been using an emulsifier his "water in fuel" light would have come on before that water reached his injectors and blew them apart. Maybe.
