I just got my report from Blackstone for my 15,000 mile oil change. I changed my oil at 5k, 10k and 15k with the Toyota synthetic 0w20 and Toyota filters. This was the first analysis I have had done for this vehicle. I had asked if 10k oil change interval was advisable. Here is what the 15k report said at miles on unit: 14927, miles on oil 4761 ; "You want to run 10,000 miles on the oil and that's probably within reach, but not just yet. Most of the wear metals look great, but copper is on the high side. That shows wear at brass/bronze parts. If this is only the second or third oil change, the copper is probably residual wear-in and not a problem, Otherwise, it could show something like a bushing not wearing properly. We'll see how it looks next time. The TBN was 4.8 showing lots of active additive left; less than 1.0 is too low. Try 6000 miles on the oil and check back to monitor copper." Well this was only the third oil change so I hope they are right about the copper being from wear-in. I think I will stay with the 5k OCI for the time being. Edit: Oh yeah the copper was 44 with a universal average being 6, the molybdenum was 576 with the universal avarage being 80, and boron was 65 with and avarage of 40 but they did not say anything about those. Everything else was very close or well under avarage.
