You can cause some problems with the O2 sensors when using extremely higher than normal octane levels.
Say for instance, shell octane 93, then adding some of that octane booster from NOS brand, which can raise octane levels from 1 to 4 points. Some of the cheaper O2 sensors have issues (universal ones) at least.
