Thanks all of you
But I am confused
What I underatnd is that now only two type of gasoline are available, High Octane & Premium. Is Premium RON 87 or 91 & High Octane 91 or 97??.
PSO's website mention HOBC RON 97 whereas Shell website mention RON 98. I also checked with a petrol pump & they confirmed HOBC is Ron 97.
As for Premium Gasoline, Shell & Attock oil website mention RON 90. whereas some people are saying that it is RON 87. Now all the refineries are producing lead free petrol, so I guess it is RON 90 as RON 87 contain lead content of 0.35 g/l.
Pls guide me.
