    Best to get back to Honda programming. Check if the Cat-Converter was removed from the exhaust.
    Most likely if he had his cat removed you would most definitely hear it & without a Tuner an active Engine light would be on. It's less doubtful someone would run a for example Honda-Data & not remove it from the car before it's traded in or repo'd.

    The problem for you is that you find that there is little average consumption?? for a CIVIC SI, 2.4 liter engine?

    The SI here in Chile gives 7,7/100 km in higway and 9/100 km in city(as an average). I don't know what difference you will have there or what average consumption expects there in the USA / Canada, but should not vary, it is the same car, same engine

    I personally use 97 octane gasoline
