Ran 1/2 a tank of E85 and then engine light came on and I have reduced engine power. This is a flex-fuel vehicle but if you run E85 and get a bad batch it's very likely you will be replacing the high pressure fuel pump, just like I had to do. This is a known issue by many dealers as well as GM.
Learned my lesson, will stick to regular gasoline.
