I was going to start a thread about this very subject... Perhaps I should being this is about E85.. But if I was going to start a thread It would have been along the same lines what or who has the best fuel? I was using only Sunoco in my BMW. But I also have access to BP and Shell oh and Mobile. We also have a lot of the lesser brands like speedy Q and speedway that I will not use in my BMW! Wouldn't this also be true of E85? What stations or brands have the best E85? Does it vary between them?
