Those products containing mostly petroleum distillates are not water absorbing, so they don't contribute to the problem.

Stoddard solvents are listed as the ingredients of several products ... and it's one of the main ingredients in WD-40 (which is primarily a water dispersing solvent).

For those that use & replace the gas in their tanks, or keep the tanks full on a constant basis ... additives may not be necessary. If the gas is allowed to, or by necessity has to sit for more than a couple of months, then a stabilizer may help. Filling your gas tanks to the max, prior to them sitting for extended periods, can also help ... as it lessens the evaporation/condensation exchange. A water seperation filter system, added to your boat, may be the cheapest way to go in the long run. IMHO (& I will probably be putting one on, in the very near future)

well i cant find where i read that (or heard maybe....senior moments).....but here is something from the Stabil site

Q: What is the difference between STA-BIl Fuel Stabilizer, Marine Formula STA-BIL, and the new STA-BIL Ethanol Treatment products?
A: STA-BILŪ Fuel Stabilizer is designed for use during STORAGE of any gasoline equipment or vehicle stored for 30 days or more, or used infrequently. It will keep gas fresh for 12 months, and help prevent corrosion, and gum and varnish formation. It is effective in all gasolines, including Ethanol blends, including E-85.
Marine Formula STA-BILŪ Ethanol Treatment was designed for use at every fill up for marine engines (boats, jetskis) to protect against the damaging effects experienced when using Ethanol blended fuels -- including corrosion caused by water attraction, and fuel system plugging caused by deposit loosening.
New STA-BIL Ethanol Treatment is designed for use at every fill up for all gasoline automotive and small engines for protection against these same problems.


Q: I've heard that 1) The Old STA-BIL Fuel Stabilizer is no good with the new fuels. 2) Red STA-BIL Fuel stabilizer gums up carburetors/engines 3) Old STA-BIl no longer works. 4) A mechanic told me to stop using STA-BIL, and that I should use a different STA-BIL product now.
A: STA-BIL Fuel Stabilizer is designed to be used during storage or infrequent use in any gasoline engine, and will keep any gasoline (even Ethanol blends, up to E-85) fresh for up to 12 months. The STA-BILŪ formula was improved over a year ago to include additional corrosion protection to protect against the damaging effects experienced when using Ethanol blended fuels. STA-BIL is compatible with ALL 2 and 4 cycle engines, and will absolutely NOT harm any components in an engine. The best way to protect your fuel system from Ethanol blended fuels related issues year-round (not just during storage), we recommend using new STA-BIl Ethanol Treatment. For Marine engines, such as a boat or jet-ski, we recommend Marine Formula STA-BIL Ethanol Treatment which has been specifically formulated for the extra severe conditions faced by these engines.
