I watched about 5 min of the video and to me it looked like the pressure was tracking RPM, with the gauge slightly lagging. Can you point me to a time in the video that demonstrates a large drop in pressure?

FWIW, I log oil pressure in my SPB and oil pressure holds up ok (IMHO) with a deep sump.

As for oil, I tried DT40 for track use and oil analysis showed the viscosity was breaking down pretty quickly. I suggest you find something else. For me, XP90 holds up much better, but I change it every 10-15 hours.
