Is this the same car that had high fuel in the oil?
The car goes very good so far.
I was thinking that can be an issue with PCV Valve since I never changed it, now the car has 134.000 KM the first 5000 I did with factory oil, after I put the kia dealer oil Kendal changing every 5000 km.
The car was going horrible with that oil since the first kilometer, horrible oil.
So I changed when the car had 20.000 km to petrocanada synthetic and the car just changed totally.
I used this oil for 30.000 km with OCI 12.000.
Than I changed to Amsoil with 20.000km OCI.
