I think you meant this the other way around. Turbo petrol is 10k miles or 12 months and not 20k miles. 😀The Kia Service Intervals are listed here. You don't say which engine you have, but for 2016 onwards it is 20,000 or 12 months, which ever is earliest, for diesel and petrol turbo. The none turbo engines is 10,000 or 12 months, whichever is earliest.
