Have you checked maf sensor, or air filter?
Unless it is a 2 stroke I wouldn't worry about it. Unless the engine is burning a lot of oil you have a fuel issue not an oil issue, I see a lot of Euro cars with cats 20 years old and older that have used higher zinc/phosphorous oils their whole life that are well maintained and the cats are still fully functional.
Thank you. Actually it did start consuming oil a short time before I noticed the soot on the garage floor behind the tail pipes.
ah, a bavarian here in bitog! can you please define a lot of oil? have some issues too.
The one time I saw an O2 sensor generating an efficiency code due to oil burning the car was using something in excess of 1 quart per 500 miles.
do you remember the code.? i have reasons..when i replaced the injectors ,as always there is an o2 sensor error, probably of bsc, injectors failing . i replaced them on dealership with a good will second time the same way.anyway the dealerhip mecahnic wanted me to take me a ride. wanted to replace the sensor. and lambda.i told him that i will go a long ride and the error light will turn off.just like the first time.and it did as i expected. but..
engine coolant temperature sensor (ECT) issue can flood the engine with gasoline and thinn out engine oil, also will mess with O2 sensor
1 ltr/1600km is getting up there.
I was looking around PDS on Castrol’s website and I saw that the latest API SP 5w40 a3 version had a higher KV100 of 13.5. Would that put Castrol in the 5w40 conversation?
I did not see new API SP version and just checked now. I mean, it looks like any other Group III. I would still go Motul or Pennzoil if 5W40 is a must.
Is there reason for concern due to the reduced flash point of PPE 5w40 if oil temps don't go above 250f and there's no oil consumption?
Flashpoint is not an issue. Check which ASTM they are using. Castrol 0W40 had a lower flash point than Mobil1 0W40 but a different ASTM.
Motomaster 5W40 is repackaged PPE.
