I thought about carying it on a trip just in case you can't get good gas out in the sticks some place.
Since you have a 2010, your Delphi ECM firmware has Ion-knock retard built right in. As long as you have the feature set to "active",,the system will just kick the timing back to what is required to prevent engine knock until you get out of the sticks.
(assuming you are not running a PC or non Delphi ECM)
