Almost 5 months on German Castrol Gold, Amsoil EaO57 oil filter and a full 5,000 on the AEM DryFlow. I used LC20 in the oil and FP60 in the gas. I did a 650 mile road trip to Maine the week before I changed the oil.
EQUIPMENT MAKE: Toyota
EQUIPMENT MODEL: 4.0L V-6 1GR-FE
FUEL TYPE: Gasoline
OIL USE INTERVAL: 5,058 Miles
MILES ON ENGINE: 16,858
OIL TYPE & GRADE: German Castrol Gold 0W-30
MAKE-UP OIL ADDED: 0 qts
SAMPLE DATE: 07/14/06
GC Gold 0W-30/Amsoil ASL 5W-30
Aluminum: 2/3
Chromium: 0/0
Iron: 7/4
Copper: 3/4
Lead: 2/1
Tin: 0/1
Molybdenum: 9/66
Nickel: 0/0

Boron: 10/122
Silicon: 14/17
Sodium: 9/3
Calcium: 1851/2877
Magnesium: 346/11
Phosphorus: 731/586
Zinc: 850/668
Barium: 0/0
TBN: 3.4/2.7
Viscosity: 61.9/59.8
Flashpoint: 395/400°F
Fuel: Antifreeze: 0.0/0.0
Water: 0.0/0.0
Insolubles: 0.3/0.3
Blackstone Comments: Wear still looks great in your Tacoma. The TBN read 3.4, still active additive remaining. A low reading is 1.0 or lower. The oil was in good shape physically, containing no moisture, fuel, or coolant. Silicon dropped, as did bearing wear [copper, lead, tin], even though you're running longer oil changes. Looking good! You could try 6000 miles on the next oil.
My Comments: The silicon dropped which was expected due to a good filter and the break-in is pretty much finished. The iron went up a little bit but this version of Castrol has 2 ppm of iron in it's virgin state. Very happy with the results. Lots of life left in the oil to extend my oil changes. Happy with the silicon results mainly. Shows that the AEM DryFlow is the real deal. I'm showing better than average air filtration numbers on this engine.
Trying GC Green currently with a K&N oil filter.
