R2 - The viscosity of TGMO starts at 8.5 so this did take a little bit of a viscosity hit.
Pokeguyjai - Why the comments from BS about how you took the sample? What happened? Hopefully that explains the fuel and the less than ideal flashpoint and not a problem with your tune. I would be tempted to try a different oil grade. Like Royal Purple
HPS 5W-20.

No benefit in sticking with an API licensed oil with your mods, IMO.
