the reason to remove such high pressure additives was to save the cat converter from dying early, As it created another host of problems, most (sensible) manufacturers employed different technologies to remove the high pressure areas in their engines (roller cams, bucket/shim/hydraulic/solid tappets etc) - Pakistan has no mandate to have a cat converter - infact this very forum has a ton of threads of people advising to remove the cat because it affects "parfarminss" of their econocar.

Be assured that ancient API - SC, SE, SG, SH, SL - CH4, CI and CJ oils are not going anywhere from shelves in Pakistan, the insane numbers of Honda CD70E and CG125E and ancient mazda and bedford diesel engines in Pakistan will fail catastrophically in short time.
