Below is my 2nd report (PUP 5W-20). My first one is here (PUP 0W-20):

As the smartstream is a DI engine, fuel dilution and timing chain wear are issues to monitor. Fuel dilution probably more of an issue during the winter/spring months (ranging from 0C to 12C typically). Regardless winter/summer, I try to avoid short trips, opting to combine tasks into one longer driving session (multiple stopovers, minimum 20 mins total driving time) so that the oil warms fully (rather than many shorter trips and the car cooling down between esp when driving kids to school). I'm not so familiar with how timing chain wear works but I think it's related to insolubles, which I note was higher this time (0.4%) compared to the last UOA (0.2%).
PUP for both OCIs is not Dexos 1 Gen 3 certified, although it probably meets the requirements.
My current OCI is on PP (non PUP) which carries a Dexos 1 Gen 3 certification, and back to 0W-20. Doubt it'd make a difference though.
Considering going to 10,000 km. Thoughts?
