I have an 04 supercrew with the 5.4 v8 and im looking for the best fuel injector cleaner. Iv heard that seafoam worked for some, then again some say that they let the dealership deal with that, others use the pour in the tank brands..but which is the best to do?

Seafoam man here. I've seen that stuff do some amazing things over the years. Ran a bottle through my 04 Screw (also 5.4) just last week. I usually run a bottle mixed with a full tank about every month or two. BTW I use it in everything that I own that has an engine.

Chevron Techtron in a tank of name brand gas, then lucas upper cylinder lube and injector cleaner as a maintenance additive, every 3 tanks. Calibrate your throttle too.

Where do you buy seafoam?

If you can't find it at your local autoparts store, just order it from amazon like I did. The stuff is amazing, I run half in my gas tank and the other half I put in through my brake boster. Love seeing the white smoke! Idles and runs so smooth afterwards.

Yeah, when you suck the sea foam through your vacuum line to the motor it loosen all that carbon buildup. Look up sea foam on YouTube and you'll know what I mean.

Wynns. I work at a dealership so it's free. Works great.

I just did the seafoam treatment to my truck and only go a small puff of white smoke so I guess my engine is pretty clean. I am getting ready to do a plug change at 129k miles and not knowing if the plugs have ever been changed (bought truck used with 116k), I am trying everything I can think of to help get them broke free. As I stated earlier, seafoam goes in everything and has for years. Love that stuff.
