Engine was still breaking in during this period ...I think you'll see these wear rates stabilize at a lower level.
High silicon levels in new Toyota/Ford engines are primarily from seal/gasket, leaching of "silicone" and not from dirt. Chrome, Aluminum are very low here and there is no nickel present from abrasive wear of intake valves. So you're in good shape with regards to the intake system components.
Recommend changing the FF oil filter at this point; top off the crankcase and re-test @ 30,000 km. Depending on solids level, I might advise changing the bypass filter element at that point, along with the FF filter.
Finally, a TBN test @ 30,000 km would be strongly recommended, although the oil condition looks excellent at this point.

Some of this loss of viscosity is fuel dilution due to the cold weather. It's probably reported as "O" if it's < 1.0% - but it could very easily be 0.9% in this sample. Having said that, I've noticed these multi-valve Toyota engines do shear the oil somewhat. I saw the same thing with my timing chain and gear driven cams on the 2.4L Tacoma engine.
The additive levels in the used oil looks a bit off to me. I'd have to question the accuracy of that data; particularly the calcium level.

What lab did the analysis?
Metrotech in Calgary - they have a good reputation.
TooSlick - are you referring to the calcium in the new oil or the sample? For some reason, Metrotech maxes out with calcium at 2000, they always seem to report this way. I was surprised to see them report over 2000 for the new oil.
Regarding the shearing - if this oil can be sheared down by a Toyota engine, how can it be expected to do well in a diesel engine with timing gears, highly-pressurized oil for injectors etc.?

Tommy,
The Series 3000 holds up like a rock in commercial diesel engines - better than the Amsoil 15w-40 in fact. I've seen lots of field test data over the last eight years it's been available, some of which is on the Amsoil website under "Performance Tests". I've never seen a sample shear out of grade in an actual engine.

Where did that 7ppm of moly come from?
Tommy,
Min spec for an SAE 5w-30 is 9.3 Cst, so you're well above that - this formulation never get to that level unless you have severe fuel dilution.
The moly is residue from the factory fill. It will take several changes for it to drop to 0 ppm.
