E85 issues as well as a link to find pure gas stations. 

 
Ethanol blended gas is widely used, however there are issues with it, increased fuel system corrosion, lower performance and lower mileage.
 
The energy content of 1.0 gallon of ethanol is 76,100 BTU, compared to 114,100 BTU for gasoline. That roughly equates to 1.5 gallons of ethanol having the same energy content as 1.0 gallon of gasoline.  The reduced energy content of ethanol results in lower horsepower and reduced fuel mileage. With the reduced energy content, ethanol cost more per mile.
 
Ethanol is hygroscopic, meaning it will absorb water vapor directly from the atmosphere. The absorbed water dilutes the fuel value of the ethanol and may cause phase separation of ethanol-gasoline blends, containers of ethanol fuels must be kept tightly sealed. Another part of the problem is problem is the alcohol can damage rubber, plastic and fiberglass parts, essentially eating away at them, sending tiny pieces into the engine
 

Ethanol contains soluble and insoluble contaminants.  These soluble contaminants, halide ions such as chloride ions, increase corrosiveness of alcohol fuels.  Halide ions increase corrosion in two ways; they chemically attack passivating oxide films on several metals causing pitting corrosion, and they increase the conductivity of the fuel. Increased electrical conductivity promotes electric, galvanic, and ordinary corrosion in the fuel system. Soluble contaminants, such as aluminum hydroxide, itself a product of corrosion by halide ions, clog the fuel system over time. Replace fuel filters regularly. The following items help:

Sta-Bil fuel stabilizer 8oz

Heet 12oz Water remover and gas line anti-freeze
