Here ya go bud. These are posts that I found on the issue.


From: DBLR
Have you not read where it is not advised to use any fuel additive that has alcohol in it unless you are using it to de-gel your fuel? Yes it may clean up your injectors and clean some carbon but it is not good for your fuel system and can even hurt it. To sum it up I’ll copy what DD had to say in another post about it “Fact is that alcohol kills lubricity, and that is the last fuel additive that should be used on a diesel.”

Next 2 quotes are from: DULUTH DIESEL
Alcohol kills lubricity. Every major additive manufacturer, including the stuff that Cummins puts their endorsement on, know that alcohol is a bad deal for diesels. You are not doing your engine any favors using SeaFoam. There are better diesel fuel additives that do not use alcohol.


To be fair, SeaFoam itself isn't a bad product. While it is widely known that alcohol has no place in a diesel fuel due to lubricity issues, I have used SeaFoam in gasoline engines, especially small engines, and have had good results. The only issue with SeaFoam in a diesel application is the fact that there is alcohol in it.

 

Hmmmm..... this isn't just a fuel additive, in fact its not really and "additive" at all persay. Its a one shot cleaner for both the fuel and crank case oil. You don't put it in your tank, you add it to the fuel system at the nearest point you can to the injectors and you use half a pint, one time, let it burn off and your done. No lubrication issues at all. Then you add 1.5 pints to a 15 quart crank case, run it 10 minutes and change the oil.
What you posted sound more like a different product is being described. Am i wrong?
I havn't read the ingrediants so i did not know if it was alcohol or what, i'll have to look.

 

i beleive your right CHenry, its not so much an additive as a cleaner, you put it in the filter run it for a minute and its gone, just a quick cleaner, after thats gone your back to diesel, i cannot see where that could hurt anything, the truck runs fine off of it, it may contain alcohol just by the way that it smells but i dont think that it would hurt the truck at all

 

Heres another dumb question, it says to add it to the fuel while its running... i don't think removing the filter top while its running would work out to well. So how do i go about that?

 

I bet the running thing is when adding to the egr. I used in in my gasser and Chevron makes a much better injector cleaner. IMO I wouldn't use it in my truck.

 

I have run it in Diesel Tractors, my truck, cars, chainsaws, weedeater and about everything else I have with motors on it and have always had positive results. In all the gas stuff I feed it in through a vaccuum line while it's runnin and in the diesels i fill the fuel cannister when I'm changin the fuel filter. If you were runnin it through full tanks of fuel I could see it being a problem with lube, but I think PS and most other things sold as lube are to. Filling the filter with it means that within a minute or two it is gone and burnt up. and lube is back to the pump before it has a chance to get hot or create problems.

I have run it through the oil, but never really noticed any differences being made in that area. But it deffinately does help if you fuel system is gunked up.

 

While no experice with it in diesels, like others I have good results in small engines.

I have one friend that swears by it for the summerizing of his sleds instead of stabil. His carbs are spotless after sitting all spring/summer/fall.

 

Well i used it and the truck seems to run a little smoother...seems fuel milage is reading higher by 1 or 1.5 mpg...thats from the computer readout which according to past calculations is within 1 mpg of being accurate.

 

Alcohol is real tough on the lubricity of diesel fuel. I advise against using it, especially with newer sensitive (non oil lubricated) injector pumps. Sea Foam is great in gasoline engines, and I've used it extensively in the past. But I won't dump it in a diesel, and certainly not with my VP44. Power Service, AMSOIL, Howes, Schaffers, and the majority of true diesel fuel manufacturers do not use alcohol and strongly advise against it in diesel fuel systems. There are ways to treat, stabilize, anti-gel, and add detergency to your fuel without Alcohol. I don't care what the SeaFoam bottle says about being fine for diesel use.

I have a Ford, i dont' have an IP. I still think the short time its in there it can't hurt anything because of the non lubricating properties it has, it burns through from a concentrated amount in the filter canister and is gone in minutes.
