Wa Alaikum Salam.
I would suggest to use fully synthetic 5w-30 only, meeting latest ILSAC GF-5 and API SN / SN plus criteria. Also ensure that oil is 100% genuine and original and by some reputed brand.
If you want best for bucks, go for Total Quartz 9000 Future Series 5w-30 only, and change it along with genuine, OEM or good quality leppon / Wix oil filter, after every 5,000 Kms. Do not drag it more than 5K Kms.
I hope, it helps. Thank you.
