auto: all these companies get fuel from two main refineries in Pk..
the ron grade here supplied is 89 and 90 ron. If you need better 100 ron octane you need contact in air force,, or air aviation in Pak because 100 ron is only supplied there.
As I drive a JDM, i take special note of keep fueling system clean. As its rated for 100 ron where as local assembled cars can handle lower fuel rating better, because Honda Toyota etc designed those engines accordingly. One good example is 2e engine simple easy to fix been used in Pk for more than last 15 years.
