i got a 96 civic, and someone told me to put it in my car, but my question is, What is Seafoam and what exactly does it do? I dont know if im in the right forum so dont flame.

 

Go to NAPA and buy it. Pretty much it just cleans carbon build up out of your engine making it run a little bit better.

You can use it three ways:

-Sucking it into your intake manny via brake booster hose
-Adding it to your gas
-Adding it to your crank case oil.


Now I'm going to ask them to lock this thread because had you clicked the "Search" button, you could have found many many many threads talking about it.

In 10 seconds I found this:

oh ****, i forgot about the search button, my bad

 

Honestly, I thought Seafoam was a color. That probably meant paint your car that color.
