48k+ on my 2008 without any leaks, but I have not tracked the car. Tracking exposes whatever problems are lurking or whatever deficiencies exist.

You could change the oil cap gasket and/or press down a bit on the two cap arms to tighten them a little. I have the early cap, but it has caused me no issues. I know a prettier one came out later and maybe it has improvements in function as well as form.

Oil leaks can be a sign of excess crankcase pressure.
