Well, hey. Since my truck is lightly pinging under any sort of load, and it seems to be much better with mid-grade, it should be a good test bed for this octane theory. It doesn't have a knock sensor so it should give a good, audible indicator if it boosts octane or not.

I don't drive it much so please don't expect my results anytime soon.

Someone with a scangauge could also record the RPM, LOD and IGN values at several points and log ABA values for each. With higher octane, newer engines should advance the ignition a degree or two for a given LOD and RPM.
