Based on Federal and State renewable fuel standards, laws and mandates/quotas over past decade, E10 ethanol blends of fuel distribution has dramatically increased over past 2-3 years.
In 2008, Florida state decisions/laws changed to REQUIRE oxygenation of ALL public gas supply at maximum federal legal limit of 10% (E10).
Unfortunately, pumps which test no ethanol today, will likely switch-over to E10 in the near future.
Not a good decision for a state with high temperatures and humidity (increased risk of gas water contamination), and many marine engines and older cars that are not designed for alcohol blends of fuel.
-Conventional, non-alcohol gasoline did NOT "attract" and "absorb" water -

Title: "Bronson Unveils New Fuel Quality Standards For Gasoline/Ethanol Blends".
In Florida, the higher humidity and ambient temperatures alone, places much greater risk of gas tanks, pumps and engines to expereince water contamination and phase seperation with E10 gasoline.
Florida has very limited availability of E85 pumps (85% ethanol gasoline used only in Flex Fuel Vehicles)- which may help to explain why Florida's Governor foolishly chose to add ethanol to all conventional gas to meet state's quota for renewable fuels this year.
It's unfortunate that engine owners in Florida have lost the right to chose and purchase the most appropriate gasoline for their particular engines.
(Check your owner's manual fuel recommendations - most older engines, pre-late 1990's, will recommend/advise or forbid against use of any alcohol in fuel).
Also note that E10 is contraindicated for most marine engines, lawn equipment and motorcycles because these engines have a "vented" fuel system, allowing easy access to mositure in air.
Automobile risk is lower since fuel system closed/sealed gas cap, plus fuel usually replaced more frequently.
Fuel-Testers company has recently received a dramatic increase in reports from consumers and businesses in Florida expereincing major problems with E10...
Problems include:
- June/July 2008: Numerous stations dispensing over 10% legal limit of ethanol at E10 gas pumps.
Highest incidence of reports to us have been from following locations: Ft. Lauderdale, Miami, Tampa and St. Petersburg area.
- Purchase of E10 gasoline contaminated with dirt, rust and sediment.
(gas pumps not properly cleanded and prepared prior to switchover to E10.
- Reports of pumps containing ethanol alcohol that do not have E10 sticker label.
(Miami and Tampa areas).
We strongly advise all people concerned about using gas containing alcohol,
visualize fuel (contaminated fuel usually appears, cloudy, dark, or has visible sediment) and
In Florida if you suspect gasoline is of poor quality or contains over 10% legal limit of ethanol...
