I would suggest fully synthetic engine oil from some reputed brand. It must be 100% genuine and original, meeting latest API SN / SN Plus, and / or ILSAC GF-5 criteria. The grade may be 5w-20, or at max. 5w-30.
If you want best for bucks, go for Total Quartz 9000 Future Series in 5w-30, and ZIC A+ in 5w-20, and change oil + filter after every 5,000 Kms, or when oil becomes dirty, or 6 months, whichever comes first.
