As well, Kia has a TSB out regarding a 'cam/crank correlation error' DTC if the wrong oil viscosity is used. It can actually cause your CVVT to be slow to respond, and will cause the DTC and a failsafe lockout of the CVVT system. I have seen this code come up (the exact DTC escapes me, but I can look it up if it's important to someone) and something as simple as an oil change (to our semi-synthetic 5W-20) has cleared it up, every time.
