O bhai. Look at the owner's manual for drain intervals.
Most probably it is 10,000 km. Use synthetic Shell Ultra or ZIC A+. Use VIC C-110 or C-932 filter.
For God's sake don't try to be over-efficient by replacing oil at 3000 km. This happened in 1960's when our grandads used foxys. Now oils, engines and materials everything is better. 1985-94 saw a great revolution with turbos, 20v and higher compression, as a result oils got much better.
