The manual reads that you should change the oil every 10k. It also read that you should replace the cvt fluid at 30k or every two years. I've heard a lot of talk about this one, I still don't know what to do. I think I'll do it by the book. It also reads that you don't have to replace the oil filer until 20k. There's a suggestion of roatating your tires every 10k. These are all recommendations for a car driving in normal conditions.
