I sent off my PTU fluid to Blackstone Labs and had them perform the standard analysis on it. The SHO had 67,500 miles on it on the factory PTU fluid. The car was tuned for 17k of those miles. I put royal purple fluid back in, and so far it seems like an improvement.
I attached the PDF file of the report so you guys can all check it out for yourselves!
Here is the general synopsis from them:
JUSTIN: Thanks for the note about the metal on the drain plug. That's always something to pay attention
to, though some metal is unavoidable. Honestly, wear metals look pretty good here, especially for factory oil
that was in use 67,500 miles. Silicon is very high here, probably from factory sealers, but it might be additive
in the oil too. The biggest concern is solids. There are large chunks of debris present. They aren't ferrous,
so we're not sure what they are, but it was a good idea to change the oil. Run 30K miles and check back to
monitor the condition of the oil.
I really am curious as to what they found as far as the large chunks. Was definitely worth changing just from hearing that. The further breakdown is in the attached pdf.
