Mobil askari limited pakistan recommended it to change at 15k kms, but 10k is the safe limit as genuine filter wont last above 12k kms.
My neighbour poured 0w40 in his aqua at 100k kms on my advice.
He’s facing no issues. Performanc has increased, and engine is way silent as compared to toyota 5w30.
People count the factor of just climate here, but forget that our enviornment have loads of dust. We have bad fuel quality here, and much more humidity.
