2006 C2S, 6spd, 60k miles. car is all stock, maintenance records are spoty at best. but over rev is very clean, 0 in the 4-6.
Car spent 06-08 in South Carolina, then 2008 to present in the Northern VA/DC area.
Waiting to vote until she comes back from the shop with bore scope results. Purchased the car about a month ago, the weekend I picked it up took it for a bout 200 mile drive into the hills, 100 miles away from home got a blinking low oil message (in my excitement over a new car/my first Porsche I didn't check the oil level before I left, kicking myself hard now) nursed it a few miles to an auto parts store and it took approx 1.6 qts to bring it up to full, drove home conservatively. Oil and filter change the next day, no visible metal in the filter or in the oil, New Mann filter and mobile 1 0w-40. I have driven about 500 miles since the oil change, I'm getting black soot on the driver side tail pipe, but no CEL, and no noticeable oil consumption (I would give anything for a normal dipstick).
Did I just make a $25K mistake in my haste? Also, would switching to a heavier weight oil make sense at this point?
Assuming I have some scoring in at least 3 cylinders, and no audible ticking. I'd like to get another 10-15k out of it before rebuilding the motor from a life/finances standpoint. Am I past that point, and a rebuild is necessary immediately, and to keep driving it will grenade the motor?
Sorry for kind of thread jacking, I'll gladly take off line.

If you're not having any oil consumption, you are probably fine. You had it scoped, so let's see!

my cyl 4 & 6 were scored to hell. I tracked the car like this and it still pulled very well. burnt about 5L of oil every 1000km but she ran like a really loud and noisy champ. lol
some here have put over 40k km on their engines after finding out it had scored cylinders.

Note that all the people saying "no bore scoring" most likely really mean that they have not exhibited external symptoms yet (if they ever will that is). My point is that without a proper borescope you just don't know, and even then you may not be able to diagnose 100% (according to the master Jake R).

Early 05 C2. 86,000 miles. Spent its previous life in the Southwest. Currently fair weather and track car only. Not a garage queen. No symptoms yet. Runs like a champ. Doing everything I can to keep it that way including installing 3rd radiator, lower temp thermostat, LN oil filer adapter and frequent oil changes.
