Morning all. 2014 KIA Rio, 116,000 miles. Synthetic oil change (whatever brand is on sale in both 5W-20 and 5W-30.) 5,000 mile OCI. Never had any issues until last oil change. Noticed consumption. No leaks. Only thing I can think of is PCV valve? I bought an OEM and will put it on when it arrives. Putting it out there as I really don't know much about the history of these DI engines. The car has ran just fine it's entire life. Only failure I have had was one of the coils failed at 100,000 miles.
