The difference is
Petromin vs shell in Pakistan,
Khaipyaa vs actual principal. There is quite a difference.
I myself buy oils blended by these folks

And also this spare parts shop oil which is actually valvoline product.

This same shop also stocks “liquid molvi” which almost never sells,
People like me buy local as its proven and has support. No time for “vilayatee shenanigans”
Of course you guys would have never heard of them, now when I was in Pakistan I opted for caltex and pso/castrol lubes as they were local principal rather than “importer” which is a beat up term now in Pakistan as people buying auction lot surplus are also called importers.
