Oil consumption
#33
Whip. Can or will excessixe consumption make its way past the PDS (problem detection system) computer?

I would get it scoped to rule out bore scoring. Blackened tail pipes and oil consumption let me to scope my 997 which ended up having massive scoring. Hopefully your issue is not that.
So, I put oil in my 09 997.2s to about 1.5 quartz low about 300 miles ago. My car has 38k miles. the only items that the computer says is I have o2 sensors that need replacing in banks 1 and 2. No other faults detected. So why this? No oil on the ground and no indication of smoke. Thanks in advance.

If you have a warranty you can have the O2 sensors fix and tell them about the oil concern. My guess is they won't scope anything until they change the oil first. You likely will have to pay for that.

Warranty
Thanks. I have a full coverage 36/36 and have an appt for the sensor replacement Wednesday. They are covered. I will find out about the other. I was wondering if anyone knew once they confirmed scoring what would happen then. Wait for the engine to go before they did anything.

Hard to believe you are going thru 1.5 quarts / 300 miles without any smoke. Drain , measure, refill to top and check oil level on same level ground each time. I think you need to have a dealer or rep indy do this to get 2nd party verification. Then if you are using that much , have it borescoped.
All of our engines are failing just like us .......most just take a long time to fail. Taking good care of them will definitely help put you in the long group but sometimes you get taken out by something like cancer or bore scoring and thats what warranties and life insurance is for.

Ok verdict seems to be in. I took the car to service. They seem to think it is the Oil separater. There is a chance I mis calculated the extent of the consumption. Anyway. She's in for pre-op now. I will update.

Whoa!! 2nd full day in the shop!!!
What the. So, it's second full day in the shop. I did get a call at the close of business yesterday to tell me it could be anything from oil separater to cats. That they were running all sorts of diagnostics. Said something about the right side was all ki up and glowing. Can someone decipher what that means as I forgot to ask I was so shocked. How could a 38k mile 3.8 2nd gen be so jacked...

02 sensor fault due too much oil
If I top off oil according to my oil level sensor my 06 2S will give me 02 sensor lights within 20 miles. I run the car half a quart low according to my oil level gauge and my 02 sensors and cats run clean. My 3.8 burns close to one quart of oil ever 700 miles while my last 996 never used oil between oil changes. Love the torque of the 3.8 just wish it used less oil than my Ford 150!

My 09 997.2 had an oil level sensor replaced early in its life. The digital oil measure is not always accurate, sometimes it's more and sometimes it's less. For example: If I leave the car idle for a few minutes and then re-check the oil, it can sometimes detect more oil. My oil consumption is more than my old Boxster S but still within the acceptable limit of what's written in the Porsche manual.
I actually make log of how much oil I put in each time, how many miles driven and where the marker of the sensor is. It's a good idea to do it if someone is worried.

UPDATE
Hi all. So, My car has been at the dealership for the past week. I had them do compression. Scope for bore scoring and changed out the plugs, right bank o2 sensor. Then finally they checked the cats. Up to the cats everything is great with the car. oil consumption was misdiagnosed by none other than me! She gonna be bad when i get her back!
