3000 kms? - thats quite a pricey deal for me. Oil change rule.
1 - use good oil filter and wet the media first
2 - use good oil (delo gold = good)
3 - make sure the oil gets nice and hot (to clean itself)
4 - keep engine in good tune.
Enjoy the ride and 5~6000 kms oil change. - my oldschool VW Golf diesel experienced that, never missed a beat, always started up, carried me where I wanted it to go - loaded, unloaded, rain or shine. The oil drained was usually black as sin but still good to go (the filter was a 1 litre capacity MANN 940)
the MANN 940 is also used in the old 2L engines and Massey tractors too - its a behemoth sized filter for that car with a piddly 1.6 litre diesel.
