Rather than wasting time putting it into the filter, just throw it straight in the tank.

well- heres the MSDS pdf-

40-60% pale oil- highly refined diesel fuel?
25-35% naphtha-I see this in diesel additives.
10-20% IPA- I did not know they put beer in it

Neither. Disconnect the supply and return lines, and run them to a small container. Don't dump any in the intake!

Oh, bad for the pump that stuff is!

so your talking about using it like the diesel purge product? Are you using the reg seafoam or the diesel version to do this? Do you get alot of smoke from it? My car has 180k on in 300 sdl '87 and its never been purged like this before...

If you want to do it that way, get the real Diesel Purge stuff.

It is NEVER a good idea to add anything to your oil or transmission fluid!

Sea Foam works well as a purge but i have not found it to work nearly as well as 'Diesel Purge'. It is stupid to believe that a single product can satisfy the needs of such a wide variaty of engines that have completely different needs. Use a product designed for a diesel that is made by a well known company.

Why? A fuel detergent is a fuel detergent. Though some are better than others. Again not brain surgery.. though many like to make this stuff magic.

Please explain to me how the "needs" are different? Sea Foam is used to clean carburetters and injectors. Diesel and gas are aromatic hydro carbons.

And as mentioned in another post about marine engines, they are better engineered (for the most part) including marine diesels.

But thats just my opinion.

Sheeesh this is just like the audiophile people that are willing to pay $1000 a foot for cables when plain ole copper wire works great. To each their own I guess.

Stanadyne was what everyone was more or less 'forced' to use. It was like...use it OR ELSE . I honestly don't know if it helped or not, cos the bloody pump leaked soon after I bought it and the car just caused me a world of hurt soon after. It was extremely good on gas though, and with my frugal method of driving, I've taken it to 50 mpg before.

I was actually pleasantly surprised when I was advised on this forum that it was not a requirement with mercs

I would agree with that. Recently I tried to do a purge with Sea Foam and the engine started nailing and didn't like it at all. I diluted the Sea Foam with diesel fuel and the engine started sounding better, but still not as good as when running on diesel. I think the problem with this product is low cetane and too much alcohol. I don't know if LM Diesel Purge cleans any better, but I know engines run really quiet on it so it's definitely a better choice if you want to do the purge.

I am referring to the diesel treatment that seafoam makes....also is that ingredient breakdown for the diesel treatment or the regular seafoam?

Silly question i've asked before but ok seafoam and diesel purge what's the main juice behind both?

it says 60% pale oil (which i've read is basically like lubricating oil just straw in color maybe like a straight lubricating oil one the iso grades idk??)
20-30% napatha spelling?
and rest is IPA which is Isopropanol (IPA) is one of the most widely used solvents in the world; also used as a chemical intermediate. See Product Uses.

so after reading that i know for sure it's not good in diesel engines correct? there always saying never to add any alcohol's i'm assuming for dryness of pump lube or some reason?? i forget but just going from the list i'd say it's bout the same maybe little less kick than diesel purge with a nasty additive maybe only used in like water removal applications i'd bet but i'm just curious since i finally found a list of the parts to sea foam

The MSDS for Sea Foam was posted. How about Diesel Purge?

The contents of Diesel Purge read:

Naptha, hydrodesulfurized heavy (what ever that is ), CAS# 27247-96-7 2-ethylhexyl nitrate, CAS# 68784-56-5 Benzene, Mono-C4-9-alkylerivatives.
