The advice is always the same... change stations, change gasoline type. It's especially questionable if the fuel has a lot of ethanol additive whether the advertised octane is correct.

My recommendation, if you don't want to muck around with reflashes:

1. Drain your tank. Fill up with V-Power at a trustworthy station. The 96 and 97 RON gasolines of other makers really aren't the same as this gas. Blaze is even better, but some performance car owners actually don't like Blaze because quality differs from station to station. Observe. If no knocking, your car is normal. If it knocks, then there's a problem and your particular unit needs a reflash.

2. Start going down, go from there to Shell Premium... then down to Unleaded. Pick the cheapest gasoline that doesn't cause knocking. It will likely bet 93-95... and even then, the 93s might not work in hotter weather if the alcohol content evaporates or goes stale... so it may be worth mixing it with V-Power or Blaze (the benefit of blaze is it doesn't rely on ethanol for RON numbers).

Simple. Easy to do. And it will tell you if the problem is really with your car or with your local stations.

I can only speak for myself for this one.
Though I didn't bother to try all fuels, what I did from the start since getting the unit was to use only the recommended fuels.

Since upto now ala pa knocking issue yung aking unit, its either that I am doing the right thing or just plain lucky with my unit...
