This is the third UOA I have run on my 2006 Toyota Tacoma 1GR-FE 4.0L V6 Doublecab.
This UOA was done at 319,459 miles on 3/16/13 with 7014 miles on oil. Previous oil change at 312,445 miles was performed on 12/30/12.
I changed the oil to Mobil 1 0W30 AFE and this report looks at that. All previous oil used in this truck has been Mobil 1 5W30 EP.
I tried the 0W30 for cold weather starts during the winter. Indeed there were a large number of very cold starts (down to -18 F). The OCI was kept near 7k miles for consistent basis of comparison with previous report on M1 5W30 EP.
I changed back to Mobil 1 5W30 EP during the last change.
Discussion of previous UOA's on this truck were in these two threads:

I am including the UOA in both an image and a code block.
