There have been a number of threads recently in which the OPs report quite high oil consumption with engines that have fairly low miles. It's hard for me to conceive of any modern engine given decent maintenance using current oils actually being worn out well short of 200K, although some of those reporting high consumption have under 100K and some of those posters report conservative OCIs.
My conclusion is that there are many engines running around with sticky or stuck piston rings.
This is one of those problems that can be addressed with a mechanic-in-a-can in many cases, but only if the owner is aware of the cause of the high oil consumption as well as the potential cure.
Is this a more common problem than was once the case?
Why would this be?
Could longer drain intervals using thinner grades play a role?
