Seafoam is a great cleaner. I use it once every 5,000 miles. And i use it in everything I own to clean the fuel system periodically.

I also use lucas and St-a-Bil.
I use red stabil for my quads and jetskis.
And I use the marine Stabil in my Porsche's.

I use stabil to prevent the ethanol damage. And lucas to actually improve beyond the gas.


The marine stabil has stronger additives than the red. Primarily for water. This is a big issue with the new fuels that have water in the ethanol.
The fuel at the pump have 10% ethanol and will soon change to more.... which is bad for any automobile. Especially for 99% of automobiles before 2006 because they were never meant to be ran on ethanol...


For me seafoam has proven that it works for me to clean the fuel and oil systems.
Both red and blue(marine) St-a-bil has also proven that it works.
Lucas, I dont have proven fact for that it improves the fuel....
