put your gear at high, WOT at very low rpm... or effectively, floor the fuel pedal when the rpm couldn't make any increase (at low rpm) especially climbing hill... u will hear the knock sound (trrr... sumthing like that)[H] [K] [S];1063674920 said:

Maybe you're right. Sounds like there's a prob with the valves or lifters.i watched the video and in my opinion, this kind of knocking not because of fuel RON value. this kind of knocking might be due to some mechanical parts failure or some valve-train mechanism not tuned/adjusted correctly. in idling (no load), the compression pressure in combustion chamber is very low.
my 2 cents only.. lets hear what taiko will say...
You hear a knocking sound, especially when accelerating. Just don't confused yourself between a knocking sound & ticking/tepet sound...put your gear at high, WOT at very low rpm... or effectively, floor the fuel pedal when the rpm couldn't make any increase (at low rpm) especially climbing hill... u will hear the knock sound (trrr... sumthing like that)
dohc vtec got no tepet sir HKS... since u are 600hp person, expect u are wellknow how ignition timing works with vacuum but not with piston speed...[H] [K] [S];1063690354 said:You hear a knocking sound, especially when accelerating.

My bad then. People tend to make mistakes sir. I will try to get you a proper answer.dohc vtec got no tepet sir HKS... since u are 600hp person, expect u are wellknow how ignition timing works with vacuum but not with piston speed...
now i agree with u sir...[H] [K] [S];1063690429 said:My bad then. People tend to make mistakes sir. I will try to get you a proper answer.
However certain causes of engine knocks besides carbon deposits or poor fuel. Maybe the ai filter clogged? Perhaps there's a tune-up issue, such as timing set improperly. During idling got em clicking sound, maybe there's issues with the valves or lifters, perhaps the engine's oil pressure is low, or there is a lot of sludge in your engine that is stopping oil from circulating properly.. Iono. Tons of possibilities...
Mesra point at Petronas also can change to petrol,but forget how much to how much..First i give the characteristics of the brands...
Esso - Its neither powerful nor inferior, i use it quite often because for every 3,000 SMILES POINT (RM1-1POINT) i get RM45 worth of petrol.
Shell - I find it very gassy, thus not that powerful as compared to BHP and Petronas.
BHP - Its quite powerful as claimed by the BHP, my cars meter shows around 9.5L/100km as compared to others brands 10.5L/100km
Petronas - Average in FC but the engine really runs silent! and quite responsively powerful too..
Caltex - Not very up to my expectation, it runs noisy, less power and gives poor FC, sometimes runs like a diesel engine la...
In terms of economy the ranking is...
(1) BHP
(2) Esso
(3) Petronas
(4) Shell
(5) Caltex
But my preference in priority are
(1) Esso
(2) Petronas
(3) BHP
(4) Shell
(5) Caltex
BTW Who want to give you RM45 worth of petrol?:vroam: (for every RM3,000 petrol filled)
