Here it is.
No worries regarding the California emissions tests. Catalyst will last forever because there is no oil consumption. Valves are fine. Everything is in good order. Engine runs like new except the choke breaker I am not bothering to replace since it's riveted, even though I have the new OEM part -- only causes rough idle with cold engine.
Regarding the history of oil and filter used, since it required SF or SF/CC, between 10w30 and 20W-50, it used mostly conventional 10w30, 10W-40, and 15w40, (Valvoline, Castrol, Mobil Delvac, and unknown oils) and TGMO 0W-20 SN during the recent four OCIs. Random oil filters in the past (including Purolator) followed with a religious use of Toyota/Denso 90915-YZZxx OEM oil filters (initially made in USA and then Thailand), and now Mobil 1 Extended Performance oil filter (old version).
