Im thinking about using seafoam before every oil change...is there any other maxima owners out there that use it often? its so cheap and it certainly helps compared to a regular change without. Everytime I use it there is tons of smoke..figured if I used it more often = less carbon buildup...

 

I use it every other oil change.....

Wouldnt go more than that though!

 

how often = never. The stuff doesnt work and the smoke is the seafoam itself. Carbon burns black, oil burns blue and seafoam burns white. Much better off using some gumout reane or Redline SI-1. This is from first hand experience.

 

Do you have scientific proof that when seafoam is added to break the carbon that it's suppose to burn black? If not please do not put up false information. There have been many member here that have used seafoam and it has help. For example me and maybe vet members on this forum.

 

Scientific proof that Carbon is supposed to burn black? If you can show me carbon burning anything other than black i'll pay you. the only false information is people saying it "helped". I dare anyone to take before and after photos. I just repaired a car that had severe carbon buildup. 2 seafoam treatments had been done on it with.....................0 results. a Chemtool piston soak and 1 bottle of Regane................cleaned it and returned compression.

 

I never said that "scientific proff that carbon is suppse to burn black. I said "scientific proof that when seafoam is added to break the carbon that it's suppose to burn black?"

 

Well, Seafoam is supposed to dissolve carbon allowing it to be burned off. Otherwise you end up with carbon bits bouncing around your chambers or stuck in a cat. Now, if the seafoam is "breaking" the carbon up and it is being burned off guess what color smoke you should be getting.........
Like i said, take before and after pics of piston tops. I guarantee you will see no change. you may see a change if you pour a bit in each cylinder with the plugs out.

 

mizzax is right on here. really the only way to clean up a carbon coated CC is to do a piston soak (and that is really more for the piston tops and rings).

problem with regular use of any strong solvent based treatment (techron, regane, BG44k, seafoam, etc) is that it will get into your oil and eat away at your bearings. occasional use 1 tank before an oil change is ok, but don't go crazy with the stuff.

and it's always a good idea to collect as much data as possible before & after any treatments to verify if it's even helping at all. this could include photos of the piston tops (point your digicam down the plug tubes and focus carefully) or compression readings (low comp means sticky rings, high comp means excessive carbon deposits).

there is a product called FP60 that is suitable for continuous use (you add it to every tank of fuel), and claims to aid in complete combustion (e.g. fewer carbon deposits). I cannot endorse or discredit the product, but it's relatively cheap and has many followers.
