E85 in stock E550
I've heard that e85 is okay to run in a stock C207 E550 and was wondering if anybody knows if its fine to put it in my tank and if so how much of e85 and how much 91 octane (I live in cali). or should I not put e85 in it at all

Manual says no to E85. Stick with the recommended fuel.
