Nothing would happen to a Jeep Renegade. You could put 83-95 octane fuel into it without issue. Compression levels are low enough. Let’s say you buy a Porsche, and you put 85 Octane in. The fuel would start combusting “detonating” before the spark plugs fire. The car would sense this via knock sensor and start to retard the timing. Thus giving you less available power.
Sort of an interesting extreme example of higher octane was would war two. Engine made later in the war required 147 octane in order to run correctly.

Interesting. So would this eventually foul out the spark plugs and or cause a lot of dirt/grim in the fuel system?

Nope. The fuel burn will not be richer or leaner. Just the timing would be changed.
