    Default Vitz Kncok in Noon

    Hi,
    Vitz knocking is not a unique topic and every vitz owner have to bear it at some extent.

    I have vitz 2007 , I have observed that it knocks only at noon. Neither in night nor in early morning hours. It is strange but it lead me to think that Vitz knocking may be directly related to operating temperature .

    Is this the case ?

    Its There Because Now Your Engine Is All WARM After Morning Startup..& Due To High Compression Of These Engines...Fuel Detonates More Easily In Combustion Chamber When HOT ...REASON Is Simply Fuel Is Detonating Before TDC....Its FUEL....Low RON's...

    Mix HOBC & Adjust Ratio...Start with 60/40 And See Where It Disappears.....Its A Common Issue In Almost Every New Car Running On Premium Fuel Here.....

    The quoted answer reminded me of a joke ...


    khan sb ripped apart one leg of a cockroach and told it to move .. it moved .. then he removed another leg and asked it to move the cockroach obliged .. this continued till cockroach had no legs ... now the cockroach didn't move when commanded .. khan sb concluded; if u remove all legs of a cockroach it seizes to listen, probably goes deaf ... :-)

    guys since i am experiencing extensive knocking issue on my 2SZ FE vitz. and the issue has been identified by pakwheels experts related with the use of ZIC A+ (5W-20) a less viscous oil. i am going to change the engine oil.

    short listed oils are mentioned below

    Caltex Havoline 5W-40
    Micking Max Super 10W-40
    Shell Helix Ultra 5W-40
    Micking Max premium 5W-50

    all of these will cost between 2500-3500 Rs. I have compared the viscosity of these oils and all of them have considerably higher numbers at 40 and 100 Degrees.

    I have had a personal good experience with Micking so inclined towards using it. probably will go for 10W-40 Max Super Fully synthetic.

    Please give your suggestions for the guidance.

    Agreed it didnt. changed to 10-40 fully synthetic yesterday. No improvement in knocking . Tough marked improvement in pickup of the car. going vroom vroom now. earlier with 5-20 fully synthetic it was like someone was dragging it behind.
