Here is 5k UOA of M1 ESP 0W30 ACEA C3, VW504.00/507.00.
UOA is 5k and there are IMO several red flags here.
First, the TAN is high and higher than TBN. This version of ESP should have slower oxidation than previous version, but as previous UOA shows (old ESP 5W30) oxidation seem less excessive. Now, that old UOA was done with more HWY miles. It is safe to say that current UOA has 90% of miles in city. That could be contributing factor to oxidation and higher iron numbers due to heavy “grocery getting” regime. KV100 is also down. Still in W30 range but again, other UOA looks much better.
Currently I have Motul X-Clean+ 5W30 in an engine. I will do UOA of ghat oil too but will run after that Castrol Edge 0W40 just to see how full-SAPS oil does in this engine compared to these Low-SAPS.
