Thanks for everyone's replies so far!

No idea, I'm using an OBD-II reader to poll a PID that claims to be the oil pressure.

I want to make sure the oil is not too thick (due to its higher HTHS value compared to other 5W30s).

According to the
engine spec , the minimum hot pressure are 6 psig @ 1000 RPM, 18 psig @ 2000 RPM, 24 psig @ 4000 RPM. Is the gauge giving me psig or psi so I can do a direct comparison?

So, what should I be targeting then if not as a minimum?

I need to take a look at the log for the track session that I ran it the hardest. I'm working on doing some summary graphs automatically for any trip data and then I can quickly eyeball rather processing them manually, which is what I'm doing now.
I use Torque Pro, and it does have a setting to log acceleration. I guessing I want a field called G(calibrated) and not G(x), G
, G(z).
