how much oil does your Boxster use between oil changes?

[Newsguy]

I haven't had my Boxster long enough to see any consumption, but my Silverado seems to need a drink between changes. I think part of the reason is the 0W-20W spec. I'm using 5W-40 in the Porsche & BMW, but then, they are about 20 years old, too!

I'm at about 101,500 on the odometer (2001 S), and change the oil/filter annually (about 5K miles, sometimes a little more). I keep checking from time to time (expecting to eventually start burning at least a little oil), but I've never had to add any between oil changes.

I know I'm not leaking any, since (as I mentioned in a post a year or two ago) I've still got the same piece of cardboard in the garage, under the engine; I've had it there for years and years---there's never been a drop of oil on it.
