What is in Seafoam Products?

Excerpt from the Seafoam website: Sea Foam was actually developed for the outboard motor and marine market back in the 1930’s. The inventor, Fred Fandrei, owned an outboard motor and it seemed as though every time he went fishing he would have engine trouble. The problems always stemmed from the gas and oil mixture, which became gummy and formed varnish between uses.

The thought of spending more time fishing than working on the motor prompted Fred, who was a District Manager for the Sinclair Refining Company at that time and had a good knowledge of fuel, to invent a product that would stop the gas/oil mixture from becoming stale. He worked with quite a few formulas before he finally found one that gave him the right results. His first test market was at Lake Freeman, in Indiana, near where he lived. When he went fishing, he would take along his formula in beer bottles and quart jars to sell to other fishermen.

Inspired by the products popularity, Fred decided to give it a name and put it on the market. His search for a name ended when a fellow fisherman who had moved to Florida called him and asked him to send some of that “Sea Foam” stuff. Fred liked the sound of it, so he christened his formula Sea Foam.

Summary: Seafoam is upper cylinder lube, some solvent, and fuel stabilizer created by a fisherman in 1930 to solve gas and oil problems he was having with his outboard motor boat. The rest of the story goes on to how Fred, then his son, and then an auto parts salesman marketed Seafoam as an engine treatment for for your car.

Seafoam

• Pale Oil 40.00 - 60.00 %
• Naphtha  25.00 - 35.00 %
• IPA      10.00 - 20.00 %

Summary: Seafoam is mostly a lubricant known as Pale Oil which is used for upper cylinder lubrication. The white smoke from "seafoaming" through a brake booster is huge quantities of pale oil wrongly referred to as "carbon" on YouTube. The solvent is Naphtha which is an an old school solvent, marginally effective for carbon deposits. IPA (Isopropyl Alcohol) was used as a fuel stabilizer and water absorber years ago. IPA boosts your octane levels, giving you more power and a better running engine while in use. Gone with the next tankful.

Seafoam Deep Creep

• Pale Oil 40 - 70 %
• Low Odor Base Solvent 30 - 60 % CAS# 64742-96-7 and 64742-47-8 
• IPA 10 - 30 %
• Carbon dioxide 3 - 7 %

Summary: Deep Creep is not Seafoam in a can, its Seafoam's equivalent of WD40 and PB Blaster. The Low Odor Base Solvent 30 - 60 % CAS# 64742-96-7 and 64742-47-8 = Kerosene.

Seafoam Spray

• Pale Oil 40.00 - 60.00 %
• Naphtha  25.00 - 35.00 %
• IPA      10.00 - 20.00 %
