I just saw an article that Wal-Mart may be ramping up to sell ethanol based fuel at their gas stations. Does GM make a conversion kit for the CTS to run on flex fuel? Here's the link if interested Plugged in: Your car, corn and Wal-Mart - Aug. 9, 2006 (http://money.cnn.com/2006/08/08/news/companies/pluggedin_gunther.fortune/index.htm?cnn=yes)

All cars built after 1990 (I think, please correct me) can run E10 (10% Ethanol, 90% Gasoline; CKA Gasahol). In chicago and the surrounding collar counties, all gas has a minimum amount of ethanol, usually 10%. The CTS should not be run on E85, and you will be able to find non-E85 at other gas stations.

That article also just talks about the option of getting E85 at Wal-Mart stations, not all pumps will pour 85% ethanol.

If you have other vehicles, use this simple equation to see if E85 is cheaper than regular gasoline.
Take the Regular Unleaded price and divide by 1.33. Example, Regular Gas $2.999/gal. Divide by 1.33 to get $2.254. If E85 is less than $2.254/gal buy it. If it is more, use regular gas.
E85 has about 33% less energy production capabilities and thus 33% less gas mileage.

GOOD POST AND MOST INFORMATIVE. Except gas is no longer $2.99. Try $3.29 which divided by 1.33 equates to a break even point of about $2.47.

I know how to MAKE Ethanol. :)

I believe he was using $2.99 as an example...not a standard for all states to follow:bigroll:

Is it possible to convert a vehicle that was designed for gasoline to operate on E85? Yes. However, there are no conversion or aftermarket parts that have been certified by the EPA as meeting the standards to maintain clean exhaust emissions. Technically speaking, converting a vehicle that was designed to operate on unleaded gasoline only to operate on another form of fuel is a violation of the federal law and the offender may be subject to significant penalties. No aftermarket conversion company has taken the initiative to certify an E85 kit that would allow a gasoline vehicle to operate on 85% ethanol.

The differences in engine size, fuel injector size, air-fuel ratio, PCM calibrations, OBD, material composition of fuel lines, fuel pumps, and fuel tanks, and other part issues among the millions of vehicles on the nation’s highways, all contribute to making an E85 conversion extremely complex. Additionally, the production of vehicles from the original equipment manufactures that are capable of operating on unleaded gasoline or E85, (ie. Flexible fuel vehicle) at no additional cost over the gasoline only model, provide little incentive for a conversion company to undertake the very expensive and time consuming task of aftermarket certification.

There is also another point to consider with E85. I don't run it but I've heard after a few tank fulls, it does better with mileage.

Also, E85 helps support our farmers and not the ... well, you know.

It might do better over time, but chemically, it is inferior. It doesn't contain the same amount of stored energy as pure gasoline.

I'd like it to be as good as gas, but it's not. Eventually, it will do better and it will be better, but right now, it's got a ways to go.

I'm a farm boy, so I want my neighbors to do well. Don't get me wrong!
