Sir,
Plz treat the examples as examples only.
Well if someone is happy by consuming local oils, then we can only suggest him that far better oils are available but as far as he is willing to change.
But I firmly believe that performance of the imported oils are far better than local oils.
All these local companies buying their base oils from Saudia or UAE. Just add the additive/chemicals which they buy from Chevron, shell, etc. and add it here. And I strongly believe they are not using the same amount of additives/chemicals for Pak. cars, as the same companies using in Europe & USA.
On the other side, Imported oils like LM, PTT, and few others are being imported in the same packing as its available in their mother countries. So quality is 100% same.
I can go on to write another 10 pages, but ofcoarse it will not matter or bring in any change to millions of our Pak. brothers who are happy with local oils.
So lets be happy whatever we are using or advising ofcoarse.
