A: Ethanol blended fuels can naturally hold up to 4 tbsp of water per gallon (about 0.5%) before phase separation occurs. Marine Formula STA-BIL® Ethanol Treatment contains a chemical that will absorb an additional fraction of a percent of water above this amount (around 0.2%), by bonding with the water molecules, allowing this additional amount to pass safely through the engine and out through the tailpipe. Any amount above this will drop to the bottom and phase separate. Removing large amounts of water (more than 0.75%) through bonding will cause poor power/acceleration and sometimes cause the engine to quit. Additionally, it can cause catastrophic engine damage. No engine manufacturer recommends removal of these large amounts of water through bonding.

When I read this the first thing that comes to mind is 4 tablespoons x10 gallons of gas = A LOT of water for this to happen. The next thing that comes to mind is they claim the Sta-Bil increases this by a FRACTION of a percent which makes me think its pointless.

Opinions?
