Comments from Blackstone:
Don't be alarmed by the extra wear metal and silicon in your Tundra's first sample. Copper is the only metal reading far enough above average to highlight. That's a pretty normal find in new engines since copper comes from brass/bronze parts, which are run on a lathe and do not receive a final polish from the factory, so they take longer to wear in. Silicon is from harmless silicone sealers. The trace of fuel isn't a concern. Universal averages are based on about 6,000 miles on the oil. Your engine should look that good after a few more oil changes.

My comments: I was kind of wondering about the low flashpoint. The reason I had the oil changed is that it felt so watery - I was worried about fuel dilution. Guess I wrong. Does anyone see anything that I should be watching. Current fill is Castrol Synblend 5W-20. I'm using the free oil changes from Toyota and that is what my dealership uses.
Thanks!
