Sea Foam vs. AMSOIL Gasoline Stabilizer
Let’s see how Sea Foam Motor Treatment stacks up against AMSOIL Gasoline Stabilizer for preserving fuel and preventing rust and corrosion.
Sea Foam Motor Treatment is a very popular fuel and oil treatment. In fact, Sea Foam could be considered a household name for those inclined to have a bit of grease under their fingernails. This article examines lab testing of Sea Foam against AMSOIL Gasoline Stabilizer in the categories fuel stabilization and rust protection.
About Sea Foam Motor Treatment
One of the main reasons that Sea Foam Motor Treatment is so popular is that it covers a lot of bases.
The company suggests that their multi-faceted Motor Treatment product offers the following benefits:
- Cleans fuel injectors, carburetors, intake valves, combustion chambers
- Lubricates upper cylinders
- Can be added to motor oil to clean up deposits
- Stabilizes gasoline or diesel fuel for up to 2 years
Regarding the fuel stabilization claims, AMSOIL Inc. commissioned independent, third-party testing of Sea Foam Motor Treatment versus their AMSOIL Gasoline Stabilizer.

Let’s look at the results.
AMSOIL vs. Sea Foam In Gasoline Stabilization Testing
The ASTM “D525” test method for oxidation stability of gasoline is an industry standard. As the test title suggests, this protocol determines the stability of gasoline under enhanced oxidative conditions.
The triple-length version of this test was used to compare the gasoline stabilizing capabilities of AMSOIL Gasoline Stabilizer to Sea Foam Motor Treatment. As the chart below shows, the AMSOIL product delivered 800% longer fuel life versus Sea Foam. The Sea Foam product didn’t even pass the standard-length test.
Rust Prevention- AMSOIL Gasoline Stabilizer vs. Sea Foam
The ASTM “D665B” test measures rust inhibitor capabilities when exposed to synthetic sea water. This accelerated test simulates exposure to sea water and therefore showcases the ability to fight rust and corrosion.
The visual results from this test couldn’t be more obvious.
Cost Effectiveness- AMSOIL Gasoline Stabilizer vs. Sea Foam
Sea Foam Motor Treatment’s official treat rate for gas stabilization is 1 US-ounce per gallon of US-gasoline (10 ml per litre).
AMSOIL Gasoline Stabilizer’s treat rate is a mere 0.4 US-ounces per US-gallon of gasoline (3.12 ml per litre of gasoline).
These products are priced similarly per bottle.
Conclusion
When it comes to fuel stabilizing and rust prevention, AMSOIL Gasoline Stabilizer vastly out-performs Sea Foam Motor Treatment.
To be fair, the Sea Foam performs a few more tasks than AMSOIL Gasoline Stabilizer. The Sea Foam Motor Treatment is known more for its fuel system and deposit cleaning capabilities. Sea Foam is very popular for these uses and for very good reason.
However, Sea Foam’s claims of offering fuel stability for up to two years, do not stack up well when compared to AMSOIL Gasoline Stabilizer.
