    Oil report looks goods. They recommend 7k oil change but I think it will be fine till 10k.

    I think so too....good to see that the oil hasn't really leached much over the additional miles :D

    (Nerd Note alert: Of course being in science, it would have been great to run a "blank" i.e just new oil out of the bottle similar to what was used in the cars they tested. The values reported are relative and not absolute. Sometimes these oils may contains traces from the manufacturing processes and the instrumentation used to detect the minute quantities of metals may have fasle detection positives)

    This is an outstanding report. The iron has increased by only 7ppm in 4200 miles. That's only 1.7ppm/1kmi. That would be very low wear for a broken-in engine--much more so for one still breaking in. The Blackstone tech commented that "...the wear could be from silicon dirt...". If the silicon were from dirt, the wear metals between the first and second report would be much higher, so the silicon is definitely harmless seal leaching.

    Good point! I was also suspecting it was just seal silicon on the report and not dirt. 10k oil changes are nice thing to look forward to! I will be using the Toyota 0/20w on all my changes.

    Looks good. So, in hindsight, do you think the first oc at 1k was necessary?

    Everyone now know that the oil is good during break in and no unusual wear is occurring. This should save a lot of people unnecessary oil changes and the potential for losing any break additives the factory may have put in. It would be nice if a few more people did a 1k report to see how other engines look for referencing.

    I did my 5k mile change last week. I didn't turn that one in. I'll go 5k miles with this oil and get a sample on that one. I haven't posted the 1500 mile one into BITOG yet.

    I have the green top M1 0w-20 in it right now.

    TBN is 3.7 at 5k and 8 at 1k. Will it hold out for 10k? It needs to be above 1 I believe?

    I think so being Hybrid plus summer time should help maybe? Will have to wait and see what happens on that report hehe. After that ill just run another one after 10k again.
