I know it's a common problem that the V6's go through a lot of oil, but do we know why and if there is a way to fix it?

Thanks.

Read this, should explain it, will also give you a solution that is proving to be legit.

On my 06 STS it was using 1 qt. of oil every 760 miles. While under warrenty Cadillac installed new piston ring. Have not used any oil between changes. I change oil when the car tell me to, 10 k - 12 k miles. Danny

Danny, you will most likely see the consumption return over time if the cause is not addressed which is the oil ingestion into the intake aircharge that gunks up the ring lands to begin with.

The only solution is to stop the ingestion (especcially after the new rings from GM) before the deposits form to the extent it interferes with ring seal agin.
