Today i happened to visit official SK lubricants website, the makers of ZIC oils(http://sklubricants.com/eng/product/product_01_04.html). What i found there was that the oils like ZIC A and Zic A+ have API-SM rating whereas ZIC Hiflo has API-SL rating instead of API-SM which the Pakistani version of ZIC Hiflo has. Isn't Pakistani ZIC more advance than Korean one?(A) KIA YEH KHULA TAZAD NAHI??
On your link click "go to zic brand site"
it will be in korean language, click english beside global Zic tab on top.
SK ZIC
Click "Products"
ZIC OW, A+ & A are API SNZIC HIFLO API SM
Its just the SK lubricant site is outdated, Visit skzic.com
You are right, thanks!!
