Addictive to Fuel for the winter storage

[Fin Addict]

I was wondering if I should add any type of addictive to the fuel for the winter lay up period. I have topped off my fuel tank but I did not add any type of fuel addictive to the fuel. Is this ok or do you suggest that I add some type of addictive?

Thank You

Gas or diesel? Gas engine you will want to use something like Stabil.

I've heard that its better to empty your tanks for storage when using gas w/ ethanol because the ethanol absorbes water out of the air.
