Had gone through this thread previously, did a quick refresher now. If you go and see the thread of additives and oil, I haven't started the discussion of the oils till now. Just to avoid useless arguments.
Also when I had to go for my first oil change - I went straight to Shell Askari IV and got the best available oil with them.
I strongly agree with @margallar that brands like Chevron, Shell etc are offering international standard products at competitive prices. Also the risk of fraud in oils is very high, so even if you are buying some fancy/expensive oil and it turns out to be "2 number" then it is better to buy a lower grade product but with assurance that it is original.
