Ethanol and Flex Fuels

[timcos]

Hi Gang.

What are your experiences using Flex Fuels?

Such as

E10 - 10% ethanol and 90% unleaded gasoline

E10 is approved for use in any make or model of vehicle sold in the U.S. Many automakers recommend its use because of its high-performance, clean-burning characteristics. In 2004, about one-third of America's gasoline was blended with ethanol, most in this 10% variety.

E85 - 85% ethanol and 15% unleaded gasoline

E85 is an alternative fuel for use in Flexible Fuel Vehicles (FFVs). A current estimate puts the FFV population in the US at 4 million, and the figure is expected to increase steadily.

This is of course off the e85.com website.

What would we do to our engines to use the E85?
