Have you tried leaving your oil level at 2/3rds full on the stick and not refilling all the way when it gets low?
From what i've read, some people experienced rapid burnoff when the stick showed full, but it tapered almost completely when they didn't fill it up so much.
Catalytic converters do a very good at masking all but the worst smoking.
Your valve guides probably are worn, but try not filling up the oil all the way and see what happens.

Plus, be diligent about measuring over several quarts of usage. If it is 380 each time after the above tips, then yes, prob in trouble. But we've probably all inadvertently overfilled, measured on a slope we didn't realize was one, car was a little warmer, sat a little less time after a drive, etc.
In short, one data point is tricky to use for a trend line...

You typically need to wait about 30 seconds to 1 minute after stopping and letting idle for the majority of the oil to return to the reservoir tank (where the measurement occurs).

From: one thousand, five hundred miles north of Ft. Lauderdale for the summer.
I noticed my 95' carrera was consuming oil so I started monitoring it.
After 380 miles it has consumed a little over half a quart. I'm praying it's not the valve guides... The car does not smoke at all. I even had a friend follow me while I did the acceleration test (6000 to 2000rpm and then flooring it) and again, no smoke.... My car has 65,000 miles on it.
first of all you're so blessed, it's not even funny. secondly, if you do the math, at the current rate rate of consumption/replacement your oil should be changed at least every 30~80 k miles... but you might want to reach in and change the filters every 4 k miles or so.... nothing to lose any sleep over.
i'm at 157 k miles in my 968. no oil burning yet, and no loss of power whatsoever... i've put my cash into a new exhaust that replaces the very restrictive oem system... now i can get the car to the limiter at 163 mph (confirmed speed) without any problem.... when i notice i have over 20 k miles on the oil, i eventually mosey on over and get it changed (M1 0w50/0w40 mix)... and i've done just that exactly 3 times since purchasing the car 80 k miles ago.... i do change the filters sometimes though.
i wish i had a car that used oil like yours... then i wouldn't have to change the oil but every 100 k miles or so, when i dropped the pan to clean the 1000 mesh metal shavings off the magnetic drain plug.

Haven't used my car's dipstick for over 15 years.........rely on the gauge and it has been fine......change oil every year or 5K now.....used to change at 3K until 2 years ago......I heat the car up and keep running until cooling fan turns on which I hear under the front fender and then check oil level gauge needle to see if it is at 3 o'clock and corresponds with temp gauge at 9 o'clock......once it hits the red range on the bottom of the gauge, I add half a quart or so.......I am down a quart every 1,000 miles or so and that is the consumption since the beginning.....car manual says that is about normal........

Someone said the gauge was useless. I disagreed and said its all I use. I didn't suggest the gentlemen do the same.
My point merely was that once you have experience with where the gauge reads in correlation to the dipstick level, there is little need to mess with the dipstick in my opinion.
With that said, the 9 foot long dipstick thats mounted horizontally and light colored is not exactly ideal for accurate measurements either.

Sit down everyone!
I own up to the "gauge not being particularly accurate/useful" comment. Its is useful if like others here you have learned what it tells your for your particular 993. My P-car mechanics have always told me it only shows a range variance of about 1-1.5 liter oil. It can read in the red zone and if your a novice you could "freak out". But really there is still 13.5 liters of oil left in the engine so this is not critical yet to the engines performance. I guess I should have been more prescriptive as its not Pistonheads.co.uk we are posting on LOL!
Did they even have these gauges on pre 964 cars?

My 96 c4s has 110k on her. Just brought her in for service because I have been putting in about 1 quart a month. Found out she's got a bunch of leaks from a few old gaskets. Decided to drop the motor and clean/replace/maintain anything and everything that can be with a well maintained motor with 110k on it. Not going to be cheap but got to do it. Can't wait to get her back.
