Hi Java,
There was a recent thread titled "Sudden Oil Consumption Causes?"

It's worth a read, consider the following comment:

If I have this right, the process will be transient, circular and self-exacerbating.
My answer, for what it's worth, is to move to a much less volatile oil such as a 20W50 or a 15W40.
Maybe Kia agree and want people to use a less volatile oil in a Turbo GDI car.
