So, here’s the deal. I purchased a 2015 Kia Sportage with the GDI engine (non-turbo). I did some research and primarily found that as long as you use Top Tier fuel (which I always do) this will eliminate the carbon build-up. I also had KIA run their fuel additive through my system to clean up any carbon. I currently have 7,500 miles on the vehicle. I am not digging deeper and finding out that these DI engines are having issues down the road. Has anyone experienced with with a DI engine? At least I have the 10/10 warranty.
I just wasn’t sure how (if any) improvements have been made on the DI engines. I knew there was a potential issue with the motor, but it seems like almost ever manufacture is going with them, so I took a risk with the Kia.
Last, is there anything other than Top Tier fuel I can do to prevent future issues?
