Fuel Additives - Diesel Forum

I know they use methyl hydrate in gasoline to remove water.... I am using fuel conditioners, but what can you use to specifically remove water from diesel?

Seafoam ought to take care of it.

In reality I don't believe that an additive can remove water from diesel. In a gasoline engine the additive mixes with the water and then mixes with the gas in order to burn it. It never changes the chemical structure of water.

That is why in a diesel you will always find a water separator on the fuel system

I could be wrong but the above is what I have been told.

Agreed. I would think if a problem were severe enough one would have to drop the tanks anyway.

Here is some interesting reading.

Yes, you want to separate the water from the diesel (instead of mixing it). The water will mess up our injectors. You can use fuel additives to keep the fuel from gelling, add lubricity, etc, but don't get one that will mix the water and fuel (i.e., contains alcohol)! Cheers!

FPPF makes an additive that actually separates the oxygen & hydrogen atoms. Unfortunately it only disperses the same volume. ie 1 oz FPPF disperses 1 oz H2O. Ok for condensation maybe. Best to use a water separator.

Thanks. I change my fuel filter on a regular basis and drain my fuel bowl, there is no issue with water per say.... but i am approaching 300000km on my injectors, and want to keep them running efficiently as long as possible. I just performed a BG fuel injection service on my truck, and I don't normally believe in the flushes and etc.... I am a firm believer in regular maintenance, and not messing with the hot oil flushes etc. However, I can say the truck idles and runs smoother with this service. I also have a customer who used the BG engine oil treatment and they were extremely impressed in the fuel economy and the power difference. They had 260 000km on it. Apparently it was noticable and cleaned the sludge out of the high pressure oil orphises in the fuel injectors. I have a free trial kit to try in mine. WAS very skeptical, but after seeing his, going to give it a try.... any one else have opinions on this?

I would be interested in how your customer gained fuel mileage and power, any real numbers?

HELLRAISER · 11-06-2009, 08:12 PM

No solid numbers yet.... however he is recording fuel milage differences and taking an average based on several tanks to take as a comparison. I can't say the increase in power would be that noticable, however I can say the truck idles WAY smoother now. I will keep you posted with numbers. I don't suspect it will be significant, maybe 5% increase, but for the price of the service, I see value in it.
