Hey guys and gals I have a stupid question that no one I have talked to seems to be able to answer. Can our Cruze's use E85 Flex? On the Onstar diags page it says this "FlexFuel E85 Compatible" I asked Chevy and they don't have an answer. They said it it was meant for E85 the cap would be yellow but I have seen in a few places that some people tried it in the 1.4's and it worked fine. (I have an LS 1.8). Any thoughts..insights into this? Flexfuel while has a worse MPG is drastically lower in price right now.
