Sea foam Eninge Cleaner
 

Anybody tried seafoam on their teg? Does it do more harm than good on high milage cars? http://www.seafoamsales.com/motorTuneUp.htm

Do a search on www.honda-tech.com, I recall reading few posts regarding the use of Sea-Foam..... I think they where all good. If you are going to consider Sea-Foam, also keep in mind MOTUL. They have a engine cleaner, if its as good as the oil they produce, you should have no problems.
