Can't believe the way these threads have gone lately, from technical to these recent threads that evidently are pulled out of the air.
From PCV faulty, 200 miles per qt, use top tier fuel, use heavier viscosity oils e.g. 5-40, Techron additive, oil usage in the Kia engine from ring and/or piston wear, valve stem oil seals worn, oil changes at 3,000 miles, etc. Are you one of the lucky ones?????????? Just give it time.
Certainly don't want to step on anyone's toes, but get it through you heads there is no preventative that can be used, nor is there anything that can be done to prevent the engine demise in the Theta II engines. There have been millions of vehicles manufactured with these poorly designed engines, but only maybe 300,000+ that have needed replacement, so far.
One day you'll be driving the car and the flashing CEL will come on and if you're lucky the car will make it to the dealership, but if the cards don't fall the right way, you'll be stuck on the side of the road when it seizes, or the car could become and oil burner to the point that Kia will do a replacement if it becomes excessive.
