Lubricants are available in 2 categories, Mineral & Synthetic.
If your car is new under 10,000kms stick with Toyota OEM mineral oil (local or imported depends upon your pocket). Moreover this will help you in case you have any warranty claim.
After 10,000kms you may shift to any synthetic brand you like.
Local oil marketing companies (PSO, Total, Caltex & Shell) now sell synthetic oil, frankly I trust these local companies rather than imported brands like Mobil, Zic, Micking, etc. which are repacked in Pakistan.
I have Altis 2010, I used Toyota oil upto 10,000kms and since then have been using Total 9000 without any complaint.
I drain the oil at 5000kms and install new Toyota original oil filter.
