Bro, I would suggest to drive your vehicle for 2000-2500 kms and then completely change oil along with filter.
I think, 20w-50 mineral oil ho ga, wo 5000 kms ki ma'ar mushkil hi seh pai ga.
If your engine, it's seals, etc. Are in perfect condition, then complete engine flush would prove more beneficial.
Switch to any 5w-30 oil from any well reputed brand; preferably Fully Synthetic with API rating of SN (if supported), from next oil change and continue with it.
