I picked up my 02 Boxster S in August last year and just brought it out of storage earlier this month (yay!). I haven't noticed burning oil at start up, but occasionally lay down an impressive blue smoke screen while driving. I've normally seen this when I've got it out on the highway, usually when I get it up to 4th gear.
My apologies if this is a topic with a lot of information available. I've searched, but most of what I can find about burning oil with these cars has to do with start up.
Does this sound like an AOS issue? Possible RMS? My driving style?
