Where did you end up going for your service?Just had my second service yesterday at 15500km. Service manager said I'm fine for changing oil/service schedule anywhere between 6K km and 8K km without any issues to the car or to the warranty. He said driving 10K between oil changes isn't recommended, nor does it fit within Kia's severe conditions requirement. So I will change oil (or service) at 7500 km increments.
Kia Canada should really sort all this out. Manual says 5,000km, the car service interval is programmed for 6,000km, and the UVO app (phone app) is hard coded for 10,000km. Almost all oil and maintenance manuals are set for 5,000miles (8,000km) for severe usage, and 8000miles (12,800km) for normal usage. Not to mention that synthetic and some synthetic blends are sitting at 10,000miles (16,000km)!!!Not to mention 5Km right? I go with every 4K miles; 6Km is just under that, and 8Km is almost a thousand miles beyond that. Either one is just fine.
