Take it for what its worth. I'm not worried about any of the numbers just yet.

^^Good info. What did it cost you do get that done? Just curious!

$22.50. They will send you free oil kits, then all you have to do is send them in. It used to be $20

Looks good. The iron is actually not bad even for a broken-in engine. Copper seems to show up a lot in modern engines (not just Toyota) and I dont know why. Mobil is using a good dose of moly to at least partly make up for the reduced zinc in the API SM formula.

Thanks for posting your results.

I was expecting to see more iron since the cylinder walls are cast in that (inside the aluminum block). It is crazy to see those copper and silicon levels so high, but I haven't done a UOA on this new of an engine before...
