Reading this Bosh Report go to the conclusions page...No Free Water! Looks like we need to go to demulsification additives just like GM said.

Been using Stanadyne PF since day one :ro) 75,000 miles and runs better than new!

i hope our fuel north of the border is better than that,many analist say it is
quaity is not of the best, another good reason to have a aux tank and fill from a high quailty volume dealer, so far to date 3 duramaxes and close to 150k no fuel treatment and all ok, but i might have to start, good info smokey

emulsifying dissolves free water
demulsifying creates it

Oh Boy:eek: ! You did it now!

... This should turn out to be an interesting thread ):h .

I use Primrose 405..... never had a fuel system problem.

Significantly improves cetane, cleans fuel injectors, provides excellent lubricity enhancement, and provides excellent rust/corrosion protection. Most importantly, PowerMaster emulsifies water very effectively, eliminating costly pump and injector damage caused by free water! You will "feel" the difference in your diesel engine! One 12 ounce bottle treats 187 gallons of diesel fuel! Six 12 ounce bottle case. For Summer and warmer climate use!

....................Been using Stanadyne PF since day one :ro) 75,000 miles and runs better than new!Not so sure I read it the same as you ~ ~ ~ ~ ~ My take is that if it is either, it isn't free water ? ? ? Perhaps I don't know what free water is ? ? Assuming demulsificaion effectively drops water out of the fuel ~ its the closest thing to free water if it moves into the pump/injectors? If its emulsified it isn't in the free water state anymore and in keeping w/their finding/recommendation? Guess I see no great revelation here to change my sinful ways :D

I do note the statement re 'lubricity is the most valuable and crucial property' statement on page 3.

We know there is water in all fuel. Demulsifying additives are designed to drop it out of suspension and collect it.

So my question to those using or endorsing demulsiying additives: Where is the water you are actively collecting?

Well, I'm guessing that if they aren't bleeding it off ~ its going out the exhaust.

This debate has been had before--but in my mind--I will say this--free water is what will cause rust in the fuel filter...instant warranty claim denial..with most dealers.

Do any of you daily/weekly drain the filters.....I try...but I forget.

For stationary tanks---with a drain at the bottom---demulsify and routinely drain.

Our trucks--well emulsify and pass through the system--that is the key unknown in that is ok to that--but there are people here who have been doing it that way without problems.

Either way...a bad load of fuel..you are screwed and better drain the tank.

When using Stanadyne, I can see small droplets of water in the clear water trap of my Racor filter on occasion.

I just had some frozen water about the size of a quarter in my Nicktane CAT filter, when I changed it.

Where's George? If I recall correctly, he indicated the emulsifiers bind or encapsulate the water within a lubricating agent that allows it safely to pass through the injectors and into the combustion chambers. If that is the case, then though it may be cheap, it ain't "free" anymore.

"A: Diesel fuel has a background "humidity" of water that cannot be removed. Water that exists freely as an emulsion or as droplets, is a concern for fuel system components. Free water flowing at high velocity between highly polished valve seats and through fine nozzle orifices causes a wearing action that approaches that of abrasion. The presence of free water, especially with entrained air and various fuel components, causes corrosion of the finely mated surfaces. Fuel/water separator filters use chemically treated filter media to repel water which then settles by gravity to the bottom of the filter. Accumulated water can be drained from the filter during recommended service intervals if equipped with a drain valve or plug. Note that alcohol based diesel fuel additives may severely degrade fuel/water separator performance.

I found this while trying to understand what "free water" is in all these discussions. I don't use any additives, but if I did, I'd use demulsifier like Gm recommends.

Just my two cents.

The OE filter media is NOT treated to help remove water. The Mga filter media is treated to help strip water, but I still use an emulsiying additive...
