There is a sense: In Germany you have several unleaded fuel sorts:
91 octane - Normalbenzin
95 octane - Superbenzin
98 octane - Super Plus
100 octance - e.g. Shell V-Power

For every used fuel you can adjust the ignition in seven steps, from 7 to 1! --- 7 for worst fuel quality, below 91 octane.

6 is for 91 octance fuel (N for Normalbenzin)
4 is for 95 octance fuel (S for Superbenzin)

maybe it's possible to drive with 100 octance V-power and adjust it to 2 or 1? And yes, if you drive with 91 octance fuel (Setup N) your car is slower, with 98 octane (Setup S) it's faster! But it is noted in the owners manual: "While driving with unleaded normal fuel (91 octane) the adjustment has to be N (Danger of motor damages)"

So if you remove your R16 plug, do only use high quality fuel! Because it is set to setting 1 then!!!

I've attached the owners manual page about the adjustment of the ignition timing.
