Hey guys I was reading up on a product called seafoam and it claims to clean your engine of carbon deposits and give you better performance and mpg. I am just scared about putting something in my engine. Any reviews? And if it matter I have a 5.4 triton ,thanks

Everyone uses seafoam and nobody has been disappointed by it

I have a can of sea foam but don't know exactly where to put it. I've read the other post but I'm no mechanic and unsure where to put it other than the gas tank. I am scared to just yank off a hose and let it suck it up - my history of luck would have me putting it in the wrong hose. I have a 06 XLT, can anybody tell me where it goes that a mechanically retarded person can understand? Thanx.

I put it in the vac line and I'm incredibly impressed with the results.

Everyone does not use it. If you think you need to use a fuel additive I would use one that actual has something in it that will help. I would suggest either Techron fuel system cleaner or Gumout with regane.

If you are nervous about it just put it in the gas tank once a month instead of into the brake booster vacuum hose. You can gradually grow confidence in the product. B12 or Techron are also good products used in the gasoline for carbon and gum deposits. One dose in the gas tank won't clear all the carbon only help with running quality over time. The seafoam product has a lubricant in it to safeguard top end lubricant protection along with naptha and Isopropyl alcohol to cut some the carbon and gum loose. Usually the truck barring mechanical damage/wear/poor condition runs better. GM shops use Techron in their products. Think it is a business decision. None of the products are going to do the job completely, just help. Carbon and Gunk are some of the biggest problems in modern engines. They just idle too much, building up the foul crud. Even hard running will not remove it all. An exhaust manifold is a nasty place to visit but a high quality synthetic motor oil and regular treatment helps.

I used it in the Mustang I had and didnt notice anything different after using it. To me it was a big waste of money.

I really dont believe in putting any kind of chemicals and crap in my motor anymore. I dont bother with fuel injector cleaner or anything like that anymore.

Here is an analysis of what is in seafoam, and why its chemistry really isn't the best out there:

And here's a paper a PEA and why it is (and has been) the best thing for fuel system cleaning for 20 years:

And here's an article on MPGs:

The chemistry doesn't back the product well. If you want to clean carbon (which there shouldn't be many using quality fuel), steam or PEA is the best in the industry. If you want to clean the throttle body and intake, take it off an do it right instead of having an additive try to flush it into the combustion chamber.
