dear skzic.
I have santro 2003. I have bought zic hiflo api sm from Makro store. After buying, I was shocked when i studied on internet at fol link and many other links about api SM, that its not for old cam shaft engines like santro, mehran, swift etc which have push pull rod system as it has less contents of ZDDP which can save camshaft, cam sensor wear etc as above mentioned old engines have very high stress on cam. Does Zic have any SG - SJ grade oil? Also on ZIC HIFLO SM, its mentioned "DOHC/Turbo Charged" and i am sure that suzuki mehran, alto, swift, santro, margalla, old corollas, and many other models are not DOHC / Turbo Charged so why you are recommending people for ZIC? Please convince us for ZIC.
Your worthy comments please.
