Fuel Testers provides information and gas alcohol test kits to manage E10 ethanol blend renewable fuels.
Marine fuel system and gasoline rules have changed since switching to alcohol oxygenated fuels.

Most fuel treatment additives that remove water are actually also made from ethanol alcohol!

-----------------------

Phase separation occurs in E10 gas, when only 0.5% water or 3.8 teaspoons water per gallon of fuel is absorbed.

When phase separation occurs, 2 layers (sometimes 3) of liquid are visible. An upper ethanol-deficient gasoline layer and a lower ethanol-rich (up to 75% ethanol) water layer.  Most marine engines draw fuel from the lower portion of tank.

Ethanol alcohol is a great solvent and cleaner, that can dissolve engine parts (rubber, plastic, aluminum, and certain fiberglass tanks), dry out hoses, remove lubrication, and more.

Engine seals and hoses shrink, swell, or lose strength when exposed to ethanol reformulated gasoline.

The amount of ethanol blended in at the pumps, is not closely monitored. Checking gasoline meets safe and legal alcohol guidelines (10% or lower), seems necessary now, until more stringent and protective laws are passed.

Be extra cautious when using E10 (ethanol/alcohol blend fuels)
in marine and boat engines...

Ethanol alcohol  is a solvent, degreaser, cleanser, antifreeze and most problematic is ethanol's "hygroscopic" properties.
Hygroscopic means ethanol attracts and absorbs water.

- Fuel-Testers believes alcohol fuels are not suitable for marine engine use.

Always check your owners manual for recommended fuel type.

Precautions are necessary when using fuels containing alcohol in boat engines.
Check your STATE ETHANOL LABELING LAWS
