87 will work but 89 is recommended?
So I was checking out my "Drive Dodge" app for the D3 while I was on layover in Seattle yesterday and found that they "recommend" 89 for the 5.7. 87 is sufficient but they do recommend 89. Thought it was interesting. Personally I'm going with 92 because I have the 91 tune and Costco only sells 87 and 92 up here. 92 CMR will be coming soon.

In case some of you guys don't exactly know what hydrocarbon.. Er I.e. " octane" does or is. This article is one of the best out there. Came across it some years ago and was just updated with more e85 info.

Use at least the recommended octane if you want all of your advertised HP in all driving conditions unless you have been re- tuned for max power with 87.
