That's pretty normal. Try a mixture of 50/50 or 60/40 or whatever that gets rid of knocking for you.
Check the fuel rating at fuel knob. If it requires RON94 (E10) then don't get regular petrol.
Mixing RON92 and RON95 might resolve knocking but not good for future maintenance and performance.
Salaam bros,@jeojunoon,My 2007 Prius (has the same engine as your aqua) started to knock a while back.Putting v-power from shell did reduce the sound but was still making a knocking sound.I went to my mechanic last week and told him about the issue.He just removed the spark plugs (were really rusty) and replaced them with iridium ones.Now the engine is just smooth as it can be even on normal petrol.Hope this helps
How much have you paid for plugs and which makers?
Had them sitting around for a while now at home...They were labelled denso and came in Toyota genuine parts packaging.
