Hi there,

What is your question please?

Customer: replied 1 year ago.
My son's 2012 Kia optima just started to use a great deal of oil 3-4 quarts in 1500-miles. The car was purchased new well maintained with 98K miles. I know that Kia has a engine issue with soft bearings causing the engines to fail no leaks or oil spots on the ground. Could, this bearing issue be the cause of this high oil use
Expert:  Mike V. replied 1 year ago.

Sorry to say it, but no.

If it's using this much oil it's got an issue with the oil rings most likely or some type of scoring on the cylinder walls.

The only way to be 100% sure is a leak down test on each cylinder.

You may also have a plugged up PCV valve. This could cause high crank case pressure and that will push oil past the rings.
