Unless you have an engine with other mechanical issues, then I find this to be highly unlikely to say the very least. Please enlighten us, what is it that you think Seafoam is doing for your engine that the standard fuel additives aren't?

 

Seafoam does clean carbon deposits when used correctly. It will not make your engine sparkling clean and I would not recommend any one use it as directed on a car with over 150k on the clock as it can disolve buildup that is preventing blowby or leaks.

Seafoam does work, but its not like you will be "wowed" by the results.

The reason manufactures don't recommend using injector cleaner is because it can degrade your fuel system o-rings. It will not harm your engine to run a can through after 150k, and it can actually remove some deposits that accumulate on the tip of the injector. Which can result in a better spray pattern. However this is not absolute and is not a replacement for full blown injector cleaning.

Lucas fuel treatment is marketed as a fuel injector cleaner but it really isn't. It is an upper cylinder lubricant

 

Explain to me how carbon deposits get on, or more importantly in a fuel injector.

 

Shipo I never said anything about carbon deposits "in or on" the injector, I talked about just "deposits" there are many things other than carbon that build up in our engines. Either way sure in our case where the injector resides outside the combustion chamber carbon build up is not as much as an issue as with direct injection engines. HOWEVER carbon is not the only contaminate removed, there are many gums and resins that build up over time. And from what I know only big name gas retailers (shell, exxon ect) put "extra" cleaning additives in their gas.

A few comments:

• The topic of discussion here is port style fuel injected engines; yes, no?
• The original premis of this thread was to keep those same fuel injectors clean; yes, no?
• Over the years I've torn down many engines and I have yet to see one with "gums, resins" and what-not which might build up over time in the spray zone of the fuel injectors; not one.
• "extra cleaning additives" is a relative matter; from my perspective, all pump gasoline sold in the U.S.A. has plenty of "extra cleaning additives". Said another way, there is no need for Shell, Exxon, or any other major brand gasoline to keep the intake clean.

 

Again, this is a debate. Lets all agree to that and LEAVE it at that...or move this to the off topic section.....PLEASE.

I personlly "feel" better using seafoam every now and then....no proof, just I can give away a few bucks every now and then and sleep better for a few days ....plus the "smoke" is cool, well my neighbors might not think so

My theory, gas has gotten better over the years, so what many of us "think we know" from 10 plus years ago does not/may not apply.

I'm going to close this thread for now.....thanks to everyone for their ideas and thoughts.
