I would say follow the owners manual except in the case of oil. It says 8k miles which I think is a bad idea for only having 1.5liters when filled. I would go no more then half that. What I'm gonna do is change oil every 3k and filter every 6k. Next oil change I'm doing an oil analysis to see where it stands with 3k if ok then I'll go 4k if not then go less....but you won't truly know until an oil analysis.
