So here is a question that I have seen many answers to, but not fit the bill. I have been wondering about E-15 fuel that the owners manual talks about, which is 88 Octane. According to the owners manual: "Non-Flex Fuel Vehicles (FFV) are compatible with gasoline containing up to 15% ethanol (E-15). Use of gasoline with higher ethanol content may void the New Vehicle Limited Warranty." According to FCA filling up with E-15 is ok, as long as you do not go over that 15% ethanol to gas mixture.
I am also old enough to know about gasoline that didn't have ethanol in it and the advantages and disadvantages of it, and what ethanol is doing to the engine on newer vehicles. I have heard that ethanol doesn't allow the same cooling as traditional gas, nor the lubricating properties. I am curious to see what everyone thinks, or is using. I want to maximize my fuel economy in my 5.7L Hemi, and am torn between Ethanol Free ($3.15 a gallon here in NC, where you can find it), and just sticking with the 87.
