Since I got one of these now, I plan to run a PUP 5W-30 VOA & UOA on it this spring, but with the recent questions about Blackstone reliability, not sure what to do.
Regardless, I run 100% Top Tier gas for the injector nozzle, this spring I'll be running CRC intake valve cleaner through it since it's a single injector GDI the intake valve gets gunked by the PCV, along with the turbo vanes.
I'm going with SpeedDiagnostics next time. The turnaround is supposed to be a week, the price isn't that much more, supposedly better quality test with better info, and, they are about one hour from me.
