Hello folks,
Here is the UOA for HPL NoVII PCMO 5W-30 in a Hyundai's new smart stream 2.5T engine. Ended up changing the oil along with transmission 56K mi recommended service, but the UOA shows the engine has plenty of life left. Here are my observations:
No change in viscosity, not much fuel dilution (1.5%)
TBN is at 7.54 down by about 4.7 units from 12.2 in VOA.
Oxidation increased from 23 to 28, 5 units increase in 6K mi.
Al level is below the VOA, which probably indicates the VOA was bogus.
Iron is around 1ppm/1Kmi.
I had posted the UOA before for the same batch: https://bobistheoilguy.com/forums/threads/hpl-no-vii-pcmo-5w-30-voa.380636/
