For the record, 1 qt per 300 miles is still within MB allowance for newer engines and yes, bad piston rings will increase oil consumption.
I don't think you have other reasonable option than drive the thing the way it is.
There are piston rings restorers "in a bottle", but hard to judge the results.
Some people like to take engines apart just for fun, but that is another story.
