I have used that stuff maybe a total of 5 times in my diesel,but only when it would idle rough. This stuff would make it idle smother and quieter. I would dump a small can in with about 1/2 tank of fuel and run it. It makes sense after reading all of the post on this tread as to why it worked so well as a cleaner. The stuff definately cleans. As to the lubricty of it, I'm kinda glad I haven't used it anymore than I have.

I know it works great as a gasoline stabilizer and system cleaner. I have had gas engines that wouldn't run for crap, add a decent amount of Seafoam, run great. I have also had Seafoam return no results on engines. I add it to all my gas cans so all my small engines get a little in every fill, it stabilizes better than Sta-Bil, IMO, and keeps the system clean. I have had engines literaly not run after a winter with Sta-Bil, but never with Seafoam. Now Seafoam in a diesel, I would never, though it appears that running Power Service isn't that great either, according to test results. JMHO.

i use seafoam alot, IF YOU USE IT AS A FUEL ADDITIVE YOU ARE AN 
, THAT IS NOT WHAT IT IS SUPPOSED TO DO, it is supposed to be used as a cleaner, i have dumped it in the oil and in the fuel of lots of vehicles, it has never messed anything up ive owned, if you dump it into your truck every time you fill up, well then you deserve a dead injection pump.....you put it in the oil and run it for a few minutes and it cleans your crankcase, you put it in your gas tank and let it idle til it runs out of fuel and refill with fresh fuel, anytime i use it i change the filter, no matter how old it is......the explorer i just sold ran 10X's better than it ever did..

I had to register to comment on this misinformation. You should at least figure out what is in seafoam before you talk about what it does. Seafoam is 100% petroleum. There is no alcohol whatsoever in seafoam. Seafoam increases lubrication. This is not up for debate, it is scienitific fact.
The quotes from below are from other misinformed people.
Seafoam is 100% petroleum. Not rumor, FACT. It doesnt have single drop of alcohol in it.

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.

This will be my last public post in concerns to 2 cycle oil. Once again someone ruined it for everyone else. They started contacting Gov't agencies and big companies. I don't need to be threaten and/or sued by either one.
so As of tonight I've delete my entire web site including my 2 cycle oil information. I will no longer PUBLICLY discuss the use of 2 cycle oil usage in diesels.

You are on the right way. A lot of diesel drivers in europe( nearly every second car is a diesel in germany) uses 2 stroke oil on a daily basis.
I wasn't sure about this hype and I found confirmation here as in many other europian sites.
Even the german military uses 2 stroke oil in their trucks - have you ever heard about a goverment sueing another one?
So no worry to get sued- they have to sue a lot more people all over the world!
