I was thinking of adding Sea Foam fuel additive in my fuel. What do you guys think of this??

Also, I read on the Sea Foam home page that they recommend removing the fuel filter and filling the fuel bowl with Sea Foam and replacing the filter and starting your engine for 5 minutes or so.

I don't know how to add a link to their web page or I would.

Smells like alcohol to me. I don't mind it in gas burners, but I keep that stuff away from my diesel injectors.

 

I've used in it gas, but I don't know about diesel.

 

My brother in law has three water trucks 466 inline IH motors he runs sea foam every once in awhile, been doing it for years.

 

Like everyone else, I've used it in gassers, but reading on the container and their web site, it is recommended for diesels also.

I just wanted to get some other views before I tried it on my truck...I'd say the jury is still out on this decision.

 

I dont sell that to my customers for a fuel additive. I could of sold a crap ton of it and help the company out with numbers. But Im not into selling parts and fuel additives to harm someone elses vehicals so I can get a few dollars rollin in the door. Don't use it in the diesels. Your injectors are expensive. Use only the white or gray bottles of Power Service in your truck. You'll be alright with those.

 

how about do a google search on seafoam and see what you come up with then decide on your own if its worth it.

 

Still dont trust it. Just change your oil every 3 to 5k. Use Rotella.. There is enough additives in there to do the job. Use a premium filter too. The better micron filtration the better. Moble 1 has a 99.8% micron filtration. Others use the Motorcraft FL-1995 filter, and other various brands.

 

I dont know why you want to run a fuel conditioner in your truck, if its having problems or you want to prevent problems. Im not trying to sell this stuff to you, just trying to help out from my experience. I have seen this stuff work wonders in diesel engines that had poor cylinder balance. Probably has saved me from replacing at least 3 sets of injectors this year. Its kind of expensive, I think a gallon is like $55 but if you are just running it in the maintenance dilution it treats over 1200 gallons, so not so bad if you look at it that way. Hope this link works.

Seems like I saw a report on the top fuel additavies for Diesels and I was somewhat suprised that Seafoam wasn't even on the test. I have run it in my gas engines and I run AMSOIL fuel treatement and cetain boost in my diesels. It does say on the side of the can and on their web site that it's safe for diesel engines.

Some folks suggest putting Seafoam into your crankcase and then running the engine for a few minutes and then doing an oil change. I'm a little leary about doing that though.

As I recall AMSOIL ranked in the top 5 in the particular test that I saw but good ol' B5 petrolium diesed/biodiesel blend was the best fuel addative on the test. I'm fairly sure that they used commercially manufactured biodiesel and not homemade stuff from your other brother Darrel.

I know people who are big fans of Seafoam, but it is more gadget per my experience.
Just like WD40 can be used on everything -good on nothing.
I used it to clean intake deposits on my diesel Mercedes and it did absolutely nothing.
Than years ago I had good results cleaning diesel system on 20 years old Mercedes by using Moly diesel purge. That stuff can be bought on ebay or at local automotive story. For some reason the big chains are not selling it.

 

I'm not particularly a fan of it either...

It is an alcohol based solvent that destroys the lubricating qualities of oil. In other words, not good for the high-pressure oil system on our trucks. It's fine and works well in a gas engine, but not in a Diesel designed the way ours is.

 

To the OP - I found 1.5 MGP increase in the last three tanks after adding Seafoam to my FUEL system. I went from 15.5 mpg to 17, which oddly enough is what I used to get 30k mi ago... At 160k miles on my injectors, the thought that maybe there were some deposits on the fuel side seemed more than reasonable.

I would not hestitate to add it again. I added a can at about 1/4 tank and put 100 miles on it.

I would be leery of adding anyting to the oil side....

 

After a quick search I located the comparison of addatives that I mentioned in my first post.

Seafoam is not a lubricity addative, it is a fuel system cleaner. Think nozzel cleaning in the injectors...
