Blackstone Reports
My first two Blackstone Oil sample reports are listed below. I will keep this thread updated as I get additional reports. Great justification for oil changes prior to the 3,500 mile mark.
They still have me as a 10w-30 but, it really is a 5w-30 as was picked up in the test.

It says that copper and silicon levels have gone up after they've been improving thus far and if his engine has been open for work, this could have caused it. I talked to someone who is a chemical engineer on here who recommended against switching to synthetic before 10-12K miles, I can't see how many you have on the paper, but I'm not too sure what to think about it either. I too am going to need a blackstone test to determine how often oil changes are needed..

Copper and silicon both increased quite a bit in the latest sample from your Infinity. Both
had been improving up till now and should have read closer to average in this sample. If this engine
has recently been opened for work, then that may have caused the readings. Else, if the high silicon
is from a dirty air filter, that may have caused the excess copper. The TBN was 3.5, which is down a
little from the 4.2 last time, but still a good reading. Suggest resampling this engine in another 3,000
miles to monitor and check your air filter. Hopefully things improve.

my Blackstone report
Here's my Blackstone report:
I'm not sure why FLFire's Copper is so much higher at about the same mileage using Mobil 1.
Total Base Number (calculated using the standard, ASTM D-2896) shows that I could go with an even longer interval based solely on the remaining "additive package", which is 4.2 when the standard says > 2 is sufficient additive. That said, I'm going to do the next one at 7500 and probably stay there due to the amount of metals in the fluid so that I can avoid unnecessary wear from free metals.
Anyone know how to do tables in a post on this forum?
