sea foam?

Thanks Guys...That was my main concern considering I run E85 a ton...I will probably just toss it in there before I have to do my next oil change.

Just so we're clear Jesse... you can run Seafoam in the oil for a short time before draining to clean out sludge in the crankcase. I would not recommend this in a new Raptor.

But a can in the gas tank to possibly clean the injectors, etc? That couldn't hurt but from J's post it doesn't appear necessary. (still makes me wonder why Ford requires you to run a tank of gasoline every once in a while. My guess was gasoline has more detergents.)

I bought an older motorcycle cheap recently... wouldn't idle. Previous owner had estimates for hundreds of $ to remove and rebuild the carbs. I figured I'd tinker with it in my spare time and the price was right. Before I tore into it, I filled the carbs up with straight Seafoam and let it sit overnight. Started it up the next day and ran some more straight Seafoam through it. Smoked like hell for a bit (it's supposed to on straight Seafoam) and now it runs like new! never touched it with a wrench. Seafoam does work.

well thats what i was wondering...some say to toss it in the intake, some say the gas tank...and some say the oil

I was wondering the same when i read the manual and it says to run 87 after running 3K of E85...i dont know why...i was wondering if it was the computer programming? i have no clue. which is why i looked into some sea foam...but i didnt want to trust it till i knew for certain it can be used on our trucks. i might toss a bottle in a full tank of gas and see what goes down. I will call my local dealership first to get a straight answer, just in case..lol i doubt it would do any harm in the fuel...but im not even sure if its even needed.

I was planning on dumping a can in the fuel tank and possibly the engine oil fill. Any one else used this before?

Also has any one added into vacuum lines. If so where are they? Says it has to feed all cylinder heads.

Sea Foam is a great product.

I would consider it in my Raptor for one reason. I run a lot of E85. Every 3000 miles on E85 you are supposed to run a tank of gasoline. I run Chevron gasoline with Techron about twice as often as required and a can of Sea Foam in the tank at 10,000 miles (or even more often) couldn't hurt. SeaFoam is recommended and compatible with E85... (Sea Foam recommends a can in EVERY tank of E85!) I'm not sure I would pour Techron into E85.

I would not perform the Sea Foam "engine clean" where you run on straight Sea Foam, but I think a can in the tank every 10k is not a bad idea.

If you run e-85 why use sea-foam? I agree sea-foam is a great product but the ethanol should clean up deposits left by low detergent gasoline.

If I were to guess why us 5.4L guys need to run a tank of gas for every two tanks of e-85 it would be for the lubrication properties of gasoline.

Has anybody tried this before? They said to do this every 10K miles...? I'm at 15K, debating.

Sea-foam works great when it is needed. Pull your spark plugs, if they are fouled, run sea-foam. If they are not, push harder on the skinny pedal!!

I use it in the winter as a fuel stabilizer.

One of the biggest advantages of Sea Foam is that it removes water from the fuel and YOU WILL get water in your tank. It happens when the tank isn't full...water from humidity condensates on the tank walls. Its one of the reasons aircraft are fueled to a "ramp load" after flying...to minimize air space.

Another factor...do you trust that your fuel station didn't have the tank lids open in a torrential downpour? I've had diesel trucks for years and always got some water out of the filter bowls. I run that stuff once a year whether I need to or not.

Sea Foam is a great product if you need to get an older vehicle to pass smog or if you have had an engine sitting for a long time that may have tarnished fuel in the carbs/TB/injection sys, or whatever, but for a low milage vehicle a bottle of techron and premium fuel would be your best bet, I dought Sea Foam would harm or even benefit you at this point.

You guys ever hear of Marvel Mystery Oil?. Been around for literally decades. Great for freeing up seized engines. Sea Foam is no where near as effective as this stuff. Google it. Have seen it used all my life in massive diesels, aircraft motors, farm power plants etc. We used it a lot in the Arctic and it really does work well. I've been using it for decades now. In the fuel tank, crankcase and even as a light lubricant. Pretty effective fluid.
