Just like the title states.
Does Chemtool work the same as Seafoam?

 

All seafoam is, is just basically mineral oil.

 

b12 works the same as seafoam. follow label instructions.
that being said here is my 2 cents....
B12 chemtool is the f'ing bomb. i used to work on diesels. diesel sludge and deposits are 10X harder to deal with than gas engines. B12 worked way better than seafoam in our experience.
