2011 KIA Forte Koup EX
My car makes the same ticking noise. I feel better that there are other people having the same issue with their Koups. I switched to Synthetic Magntec in hoping that would cure the issue, sadly no. Using, thicker oil viscosity in a car is not good these days. I know mechanics and older guys that would put in a thicker oil in the vehicle motor to quiet down the valves ticking or a bottle of LUCAS in the motor oil. I'm sure you can get away with a little thicker motor oil but not 20w50 in newer cars these days when your car calls for 5W20. All we can do is listen to that ticking sound and just hope it doesn't get any louder/worse.
