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.
If you want best for bucks, go for Total Quartz 9000 Future Series and change oil + filter after every 5,000 KMS (or 6 months, whichever comes first). Do not drag them beyond 5,000 KMS.
