This is the fifth UOA I have run on my 2006 Toyota Tacoma 1GR-FE 4.0L V6 Doublecab.
This UOA was done at 401,229 miles on 12/20/15 with 5279 miles on oil. Previous oil change at 395,928 miles was performed on 10/19/15.
This report was performed primarily as periodic check for engine issues as the truck passed the 400k milestone. All previous oil used in this truck has been Mobil 1, three fills Mobil 1 AFE 0W30 all other fills Mobil 1 EP 5W30.
Discussion of previous UOA's on this truck were in these four threads:

Looks good and very similar to the previous reports.
