I am doing a research paper on E-85 for my class. While checking references I stumbled a website trying to find the total number of flex fuel vehicles produced in the US and noticed that there isn't a single Cadillac on the list. I did some more digging and found that the 07 Esky has a larger engine and yet still gets the same mileage as a Tahoe. And since Cadillac first started experimenting with MDS I am willing to bet it has that option. Why doesn't the Esky have the E-85 capability?
