So what you are saying is, that even IF the O2 sensor could detect the extra oxygen in the exhaust as a result of usinging E10 fuel, and could trim AFR's to suit the new fuel, this would be irrelevent as soon as WOT was achieved?
I'll stick to my 98RON thanks. My shitbox spends ALOT of time at WOT

only one fuel to use hey. WOT or in the shed lol.
