last week i retuned my car with another tuner, we did on-road tuning, with A/F sensors. overall we set A/F ratio to 13:1 which is richer burn. initially we did 13:1 to churn out more hp using ron97. surprising after this setting, i tried ron95 and there were no more knocking. engine is quieter.i keep using ron95 for another 200km (I travels alot) and engine is normal.i checked the plugs color and they are healthy. i know there are engines with advance knock sensors dont experience knocking with ron95, but there are too engine experience terrible knocking with ron95 regardless they are newer/older/high performance/normal engine.

imho, in a long term, investing to get a piggyback and richen your A/F enables you to run ron95 safely without headache, is a good idea.

Ron 95 flashes faster than Ron97. So you run rich, you may be getting the correct combustion timing with Ron95 rather than Ron97. Again, you are not that SR18DE guy are you?

If 95 burns faster, why does it knocks on high compression engines ? plz explain, im stupid.
