    The oil is doing its work i.e. cleaning the engine. There's nothing wrong with engine oil getting black. It just that ustaads have brain washed majority to believe that black oil = zaya, fazool etc.
    Almost everyone in Pakistan is doing corruption to the extent they can. Our leaders are doing at the level they can do. So why should we complain?

    Darkening oil means deposits are being cleaned by the oil. However, in some cases the oil tends to get black faster due to slightly worn out rings.

    Nothing seems Wrong.
    Synethetic oils do the cleaning job well.
    Did you use first time 5w-50? If yes then which oil you were using before?

    I have Crown with 2JZ Engine. Am using ZIC A+ 5w-20. And after running 500 Km, the oil color is like 50% black.
    BTW, what fuel average its giving?
