excessive Oil consumption Boxster S

[seningen]

Short trips where the AOS is pushing oil into the intake
-- or extended sitting where the oil might work its way passed the rings.

Either case you would see puffs of smoke on startup.

check your coolant to be sure there is no intermix.

if you suspect too much oil being burned in normal driving
you can check your compression.

You can also check the intake and see how much oil residue is
in there -- it could be your AOS (or aos control) is acting up and its
pushing oil into the intake all the time.

For my car 2003S with 62M plus miles consumption is pretty much 1 quart per 6,000 miles or so . This is in city driving.

I found the section of the owner's manual that talked about oil consumption.

I completely agree it "may" be the use of Mobil 1 (assuming 0W40)...try a heavier weight, as suggested. You are heading into summer there and temps will rise. I've read articles by Jake Raby and Charles Navarro suggesting the rings in the M96 are "loose", contributing to fuel getting past, into the oil; a heavier weight would discourage this. I only drive my '02 in fair weather, use 10W40 high quality synthetic and never need to top off.
