I am going to change to Fully Synthetic at 1000km's
I am waiting for the service dept to get back to me , obviously 5W30 is recommended but i think 5000km intervals will be my distance once i change this break in oil out.
I am keen to try 0W20 i have that in our Cerato GT at the moment and the economy has never been better but will go a bit thicker come winter time.
Might even try 10w40 in hers because i am getting virtually nothing in the catch can ?
I plan on keeping the car for the long haul. Got the 8yr/200000KM Kia 5 Star warranty when I bought the car to help cover any unforseen and expensive break downs.
