Hi! Anyone with a 991.1 GTS or 991.1 S could do me a favor and provide their "O110 Engine oil level sensor" reading using ThinkDiag or similar? It's under Engine Module > Read Data Stream > Oil pressure > O110 Engine oil level sensor

Thanks!

 

So you’re looking for oil level numerical reading -- as it relates to the pictogram ? I could do this with PIWIS tonight (if Piwis does that which I’m sure it does...)

 

Thanks! Exactly. I'm reading 2.79inches on mine and the pictogram sometimes shows it as full (i.e., all green bars except 1 blank at the top) but sometimes it goes down to one under full (i.e., 2 blanks bars). I'm trying to monitor oil consumption going forward.

 

hi Nashvegas! Any luck getting this info with the Piwis? Thanks!!

 

I haven’t yet - sorry. The car is not at my house right now due to a move, It’s on my list though.

 

OK @JLCarrera here you go.

First off, screenshots of everything for anyone else wanting to try this.

• My car currently is at 2 bars (guess I should top off, but smack in the middle)
• First I tried it in Instrument Cluster ---> Actual Values Input Signals ---> Oil Level Via CAN. This gave me a reading of 50%. Not what I was looking for but explains the 2 bar reading. (out of 4 being full, 5 being overfilled)
• Then I found the reading in DME ---> Actual Values Input Signals ---> O-Oil Pressure Control ---> O110 Oil Level Sensor ---> 65.938mm was the reading.

So it seems 2 bars = 50% full which corresponds to 65-66mm on the sensor.

 

BTW I searched around and found a little table in the 997 forum showing oil sensor (in mm) and gauge position in the cluster.. It’s 997 - and unsure where it’s from - but it does seem to contradict the measurement I took today. It says, at least on a 997, that 65mm corresponds to 3 bars, not 2 , in the gauge cluster, so be careful I guess you don’t use 997 tables/charts in your research. Seems different.

It would be cool if we could put together of actual readings to figure out a table like this for 991.1 Carreras. I realize it may be diff values for Turbo or GT cars.

xx mm - 5 bars (overfilled)
xx mm - 4 bars (100%)
xx mm - 3 bars (75%)
65mm - 2 bars (50%)
xx mm - 1 bar (25%)

 

Thank you so much Nashvegas! This is incredibly helpful. I agree it would be good to put together actual readings. I'll add to yours:

5 bars (overfilled)
- [x]
4 bars (100%)
- 71mm (2.80") - @JLCarrera 991.1 4 GTS
3 bars (75%)
- 68mm (2.69") - @JLCarrera 991.1 4 GTS
2 bars (50%)
- 66mm (2.59") - @Nashvegas 991.1 S
1 bar (25%)
- [x]
0 bar / triangle (min)
- [x]

 

The number of bars indicated is an only rough indication of the actual oil level in the sump. Each bar covers a certain range of oil levels (ca. 04 ltrs.) , and it changes at ahigher level upwards as the next higher one will change downwards (hysteresis, required to get a steady indication). To make it even more complicated, if the engine has run before, the indication of bars is corrected for the temperature and the time elapsed since stopping the motor, to compensate for the amount of oil not yet returned to the sump.

After draining the oil of my 991 (MA1.03S ) and refilling with 7.5 ltrs, the oil level (cold, over night) read 71 mmm, indicating 3 bars.

Remember, Porsche recommends not to fill up more than to 3 bars if you want to drive it at high lateral g-forces.

 

Interesting -- i had not heard this before. Do you have the source? I would have thought it would be the opposite. Thanks

 

It can be found in the Owner's Manual for the 991 GTS, "Recommendations for track use". I assume the background is to avoid foaming of the oil, causing starvation, by too much oil splashing caused by the crankshaft.
