Current odometer reading: 184,997 miles.
For the first 90k, I followed the Toyota recommendation of 10K drains using 0w-20 full synthetic.
From 90k - present, I have been replacing the oil and filter every 5K miles.
About 75% of the time I used Mobil 1 EP 0w-20. The rest of the time has been various other brands (TGMO, Pennzoil, ServicePro, ACDelco).
The engine valve cover and timing cover were removed in preparation for cylinder head removal. The headgasket failed last week and is dumping coolant into cyl 2.
