This is @High Performance Lubricants' entry-level PCEO 5W20.
Lots of short trips - most trips are under 5 miles. I doubt the engine oil gets very warm in a hybrid engine used for this type of service. The oil was in use for 10 months. Elevated Silicon is probably from RTV; the timing cover and camshaft housings were resealed 10K ago.
I did not run a VOA of this oil so I am not sure what the baseline oxidation and nitration values should be.
Toyota's recommended interval is 1 year or 10K, whichever comes first.
