How does a "knock" feels like? Is it like a forward jerk?

[Typhoonz]

Then it's Synergy F1 for me from now on liao...

Shell has 1 up... Super 97 and V Power... Price also different...

I've not experienced it, but I believe it's a loss of power when the petrol self-ignite during the compression stroke before the spark is applied.

 

It should sound like metallic pinging. A knock sensor can compensate the timing and reduced knocking up to a certain limit.

Quickly buy toluene and mix 50-50 That'll get your Octane upto 100.

[Typhoonz]

Where to buy?

PM you liao..... but if you're not sure how much to mix, go easy on it hor...... try maybe 30% first and then go higher if your car can still benefit from higher octane. Else, higher mix will only waste it.... and its not cheap.
