Important: All engine warranties do not cover fuel system damage when excess alcohol (above 10%) is found in the gas tank. E15 is not intended to replace E10 and is considered a specialty fuel. (Only Flex-fuel vehicles designed to run on E85 are approved to use new E15).
The relentless ethanol industry recently stepped-up their advertising campaigns to defend the rising quotas set forth in the RFS (Renewable Fuel Standards) that has pushed more ethanol into our fuel since 2004. See e-NEWS below "FuelsAmerica.org" campaign launch.
The EPA approved E15 waiver in 2010 "for use in 2001 and newer autos". Immediately following E15 approval, several class action lawsuits were filed against the EPA. Even the most impresssive legal actions to stop sale of E15 taken by several engine manufacturers and groups were dismissed in federal courts. Plaintiffs (against E15) include,
American Petroleum Institute, Alliance of Automobile Manufacturers, National Marine Manufacturers Association,
Outdoor Power Equipment Institute, National Petrochemical & Refiners Association and others.
Only testing gas for alcohol percent before purchase
can assure ethanol content is below the legal 10% limit.

- Protect your engines by testing gas for alcohol % + water contamination -
#1 Reason for gas-caused engine damage = Phase-separated E10 gasoline.
It's simple science...
- Alcohols attract and absorb water,(that's what alcohol is supposed to do);
- Oil and water do not mix;
- -> Result: After water absorbed, (oil-based) gasoline separates into 2 or 3 layers.
After phase separation, most water + alcohol drops to the bottom of the tank;
Now the lower layer of tank contains gas with an alcohol concentration of 60 to 95%!
Running gas with a high alcohol concentration will compromise and damage all engine types. *
Always test ethanol percent/concentration of fuel, at time of purchase
and especially after prolonged storage. View Spring E10 Gas Tips.
Notes: Typically E10 gas type phase-separates when only 2-3 tbsp. of water/gallon enters fuel tank. Most newer engines can tolerate 10% ethanol concentration, but a higher alcohol concentration will cause damage & performance problems. Running gas with EXCESS ethanol usually occurs due to (1) Illegal over-blending (2) Phase-separation
* Comments do not apply to use of E85 fuel type used only in FFV (Flex-Fuel Vehicles).

FAQ - Frequently Asked Questions
Can I safely use E10 type gas in all my engines?
Answer=It depends on several factors...
Most modern engines are designed to run on ethanol blends up to 10% alcohol. The primary reason most experience problems with E10 is solely due to gas sold that is contaminated with excess ethanol and/or water.
IMPORTANT: Phase separated E10 fuel is the primary cause for all "E10 gas-caused engine damage".
Common symptoms of excess alcohol or water in gas:
Vapor lock and fuel starvation (stalling, hesitation, inability to start engine), corrosion/rusting, premature disintegration of fuel pump, oxygen sensor damage, clogging/plugging of filters, fuel injectors and carburetor, reduced gas MPG... More E10 gas problems/damage...
For prolonged gas storage, it is always safest to leave gas tank empty, when E10 is only gas type available in your area.
E10 gas will only remain stable (water-free) for a maximum of 3 months, when stored under ideal low humidity conditions. Gas without alcohol stayed stable for years.
Important: No gas additive can prevent ethanol's natural ability to attract/absorb or remove water in a sedentary engine. Products such as Stabil, only "perk-up" stale fuel by increasing energy content; They do NOT prevent or remove water from gas tank.
No miracle gas additive exists that will prevent or treat the most common causes of (E10) gas contamination...
Gas additives that are most useful (preventive) will contain ingredients that raise the BTU energy, raise octane (which drops 2-3 points when gas phase-separates) and most importantly will lubricate to protect engine parts from the drying,solvent and deterioration effects alcohol causes.
---> Always check product ingredients before use with E10 fuel type. Most gas additives that have been in the marketplace for years, contain strong solvents, cleansers and/or alcohol, which is contraindicated for use with E10 gas type. Example: All gas antifreeze products contain 95% or more alcohol, which is not only unnecessary since the 10% concentration of E10 is plenty, but excess ethanol will increase risk for water absorption and parts damage.
- E15 is now being sold - EPA issues plan to mitigate engine damage from mis-fueling...More information.
- Mercury Marine releases study- A blend of 15 percent ethanol and gasoline caused so much damage to boat engines during a government-funded study that the testing of two of three motor types ended early. Study released October 2011.
- FUELSAMERICA.org: After eight state governors, (North Carolina, Texas, Arkansas, Georgia, Maryland, Delaware, New Mexico and Virginia), petitioned the EPA to waive the RFS, a large coalition of ethanol promoters joined forces to defend RFS, launching a high cost advertising campaign on Sept. 27th, 2012. The stakeholders include: Advanced Ethanol Council, American Coalition for Ethanol, National Corn Growers Association, Growth Energy, Renewable Fuels Association (RFA) and others who have relentlessly manipulated the EPA to replace our primary type of conventional gasoline to ethanol-blends. Ethanol-free gasoline is now a specialty fuel almost impossible to locate.
- Florida legislation to repeal the state's mandate for 9 to 10 percent ethanol was postponed... See HB 4013 and SB 238.
New Hampshire's attempt to ban ethanol in gas failed (20011-12). See HB 374. Details (boston.com):
Many changes are taking place in all states and worldwide, both pro and anti-ethanol.
