This is the third full interval with the M1 ESP Formula 0w40. I pushed it past my usual 20% OLM reading and let it go down to around 3% which was around 2k extra miles. But this also worked out to a lot of track time: about 15 hours! Several of those track days had ambient temps in the mid-90s but overall oil temps and pressures stayed steady. Never got oil temps above 265 F.
Blackstone said that overall it looked good, but again noted the viscosity was a bit low. I've since switched to Motul 300V 0w40 which I hope holds its viscosity a little better.
I'm still really impressed with how this thing continues to hum along without any major issues despite the hard driving. I just had it dynoed last month and it laid down 400whp, meaning it's still producing the claimed 460 crank hp (if you assume 15% drivetrain loss).
