My girlfriend owns a 2011 Grand Cherokee with the HEMI. Just was wondering if the 5.7 was considered a FLEX fuel ready motor? I'm sure it most likely is, just didn't see any FLEX fuel badges on the vehicle. Thanks
Sure you can, you will just lose 25% mpg's due to the motor not having the necessary compression for ethanol.
Here ethanol is only 15% cheaper so you pay more to run the E-85. But if you want to save the environment and reduce your dependance on oil while increasing costs of pretty much every other good then it would be good to run.
edit: missed the part where OP said no badges present. so no you cant. But the above info still stands.

The Hemi isn't a FLEXFUEL motor as others have said.
However the absense of badges shouldn't be an indicator. My V6 has no FLEXFUEL badges, but it certainly is FLEXFUEL capable and indicates that on the fuel cap.
like COLO said, I don't see the point. Here E85 (where you can find it) is $.10 a gallon less. So, in a 22 gal fillup it saves you $2.20. However, you get about 5MPG less on average, which is huge. So overall Ethanol will cost you more.
