I dont understand the question.

Some results from Consumer Reports. These are catted though. The numbers are so low, that its difficult to say what it would be uncatted in this test.

E85 is often heralded as a way to reduce air pollution. Since increasing concern about global warming has focused attention on greenhouse gases, we decided to track our carbon emissions during this test.


By relating our observed fuel economy to CO[sub]2[/sub] emission figures found in the EPA's Green Vehicle Guide we determined that our gasoline round trip produced 706.5 pounds of carbon dioxide. On E85, the CO[sub]2[/sub] emissions came to 703.1 pounds. The difference came out in E85's favor, but only by a scant 0.5 percent. Call it a tie. This is certainly not the reduction in greenhouse gas emissions we had been led to expect.
