I just bought a can of Sea from on recommendation from a neighbor. I am hoping that it will help with a rough running Expedition that had sat for 10 months.

Anyone have any experience with this stuff? Is it the miracle cure I have been told it is?

I used it in my 05 prior to plug change. I also just used it in my Taurus last weekend. Follow the instructions and don't fear the smoke that will be coming out of your exhaust :)

OP didn't mention, but if the gas in the tank is 10 months vintage, then I'd start there.

If fresh fuel and still running rough, I too have had good experience with Sea Foam. You have two options, dump a bottle in the tank or have the engine ingest it via a vacuum line. Quickest and best in my opinion results will be via vacuum line and the smoke will let you know its working.

EB=Eddie Bauer normally here. They are referring to the ecoboost motor though and to avoid using it on one.

I've never used the spray, only the original... maybe the spray is a different concentration?

The spray is the same stuff it’s just a spray to make it easier to put directly into the intake instead of trying to pour it into a vacuum hose or something.

Ok I'm not a mechanic & seldom have a clue about vehicles. Seafoam? What's the purpose?

It's an additive that helps remove carbon. It can be used in the fuel tank, in the crank case oil, or you can add it slowly via a primary vacuum hose directly to the intake manifold.

Sea Foam is like paint thinner for your engine. It works the same way. It is made of naptha, kerosene, and isopropanol alcohol. These liquids dissolve engine deposits (mostly carbon). It also can dissolve the varnish left behind by gasoline, and when placed in the fuel tank, acts as a gas dryer (absorbs water and carries it to the engine for disposal).

It works when used properly. It can also be used as an additive to stored gasoline as a stabilizer. Its been around for decades.

Again wouldn’t use it as Ford advises not to use any type of additive on EB engines, not sure about the tritons though. Might be ok for then

Sea foam sounds like a newer version of marvel mystery oil. We had a member a few months back that had a 3 valve 5.4, 2006 I think. Well not knowing how sensitive the cam phasers were on those motors, I'd suggested he put in about a half a small can to unstick what was possibly causing his top end ticking. Well all hell broke loose, he overdid my recommendations, and on top of the marvel, he dumped in 1/2 quart of atf. I had told him one or the other. Luckily he swapped out the cam solenoids at front of motor, along with an lof, and brought his racket back to normal. I don't usually recommend carbon burn off as it can dislodge chunks that can get stuck, or cause damage. If you do decide to sea foam or use any strong carbon burners, be sure to drop oil/ filter immediately after, as your dropping those chemicals into your oil. But you all knew that already.

Do you happen to know what the official, Ford approved method is for cleaning the valves and such on these EcoBoost motors? Is manual cleaning allowed/recommended (i.e. wire brush or media blasting)?
