Seafoam in engine oil - you've got to be joking.
Noticed that some members are putting Seafoam in their engine oil and running that way.
Seafoam is a mixture of ordinary oil at 40-60%, Naptha at 25-35%, and IPA at 10-20%
Naptha is gasoline purified to have a low vapor pressure (also known as "white gas")
IPA is Isopropyl Alcohol or Isopropanol - a form of alcohol.

cleansed, not coated
On the other side of the engine block are those additives which will cleanse your engine, not coat it. Stuff like Bardahl, Rislone and Marvel Mystery Oil claim they can make your engine run quieter and smoother, and reduce oil burning. These are products which contain solvents or detergents such as kerosene, naphthalene, xylene, acetone or isopropanol.

But unless you have a really old and abused car, you probably have no need of stripping away sludge and deposits from your engine. Thus, you probably have no need for these wonder cleaners. If you overuse such products you can damage your engine by promoting metal to metal contact.
If you use a synthetic oil, such as Mobil 1, you are advised not to use any engine treatments or additives. Mobil claims that
The use of an engine oil additive is not recommended, either by Mobil or by virtually any vehicle manufacturer. In fact, it may void your new-car warranty.
