Homemade Seafoam Knockoff




Introduction: Homemade Seafoam Knockoff

Somewhere near the front counter of nearly every automotive store. You will see a small red and white container of seafoam for $12 a bottle. As it turns out it is not a very complicated product and only consists of few ingredients. you can actually find the MSDS of seafoam online http://www.sueschauls.com/Seafoam_motor_treatment....

The ingredient are as follows:

40-60% Pail Oil: Deisel Fuel, Automatic transmission fluid, or a light motor oil.

25-35% Napatha

10-20% IPA AKA: Isopropyl Alcohol

Step 1:

So now that you have you ingredients to make your own engine additive. You just have to mix them together and store them. Its easier to remember as the 4-2-1 method. 4 parts pail oil, 2 parts Napatha, 1 part Isopropyl Alcohol.

I just use a measuring cup and store in a 1 gal container. The measurements are as follows.

4 cups of diesel fuel

2 cups of the Napatha

1 cup of Isopropyl Alcohol.

When treating the fuel I use the seafoam dosage recommendations of 1oz per gallon. Just to be on the safe side. Now I do not claim this dosage or ingredients to be an exact replica of the seafoam brand itself. Im sure they have other additives, or blends added. I am going off of the MSDS sheets and from what I have learned through my research online. It is always better to be safe than sorry. I am not liable for any damages that may occur.

    Very interesting idea. Did some research myself and found more info on this site:


    If you have an idea as to what you're doing you can make some substitutions for a better product. You have the most to gain by playing whit what's used as "pail oil". I would love to try biodiesel as a pail oil, as it has stronger cleaning ability while still enabling lubrication. That or biodiesel/gasoline mixed at around 2:1
