Looking at the report I noted that the magnesium is at 130 whereas the highest previous reading was 24. What do you think? Engine issue or new oil?

I've had a couple of blackstone reports done on DT40 in my '98 boxster SPB. Both of them showed magnesium around 150. Based on this, I'd say your change is due to the oil. Also interesting to note that my reports have shown low viscosity (10.4 & 10.8). I see yours are better than mine, but at the low end of spec.
