I wanted to follow up as I am finishing the 2nd part of the S2000/FRS video and due to the scary low oil pressures on 0w20 with forced induction oil cooler and very modest power. (low 40s PSI at 225F Oil Temps)
Prior to the "race" we switched the FRS to Redline 10w30.
Now of course today we happen to get near record cold at 39F.
It's a can't win scenario.
Cold start was 120PSI. But the worst part was between the cooler and the oil during the day at 55F, oil temps would not exceed over 175F street driving and pressures remained much higher. (Perrin Oil Cooler with Mocal Unit) Not until we sat at idle out of open air did oil temps hit 185F which mean oil pressures were high all the time.
Quick Comparison:
0W20 Redline
0w20 Redline 185F @ 800RPM 10PSI Oil Pressure
0w20 Redline 185F @ 2000RPM 35PSI Oil Pressure
0w20 Redline 185F @ 4000RPM 54PSI Oil Pressure
0w20 Redline 185F @ 7000RPM 65PSI Oil Pressure
10W30 Redline
10w30 Redline 185F @ 800RPM 19PSI Oil Pressure
10w30 Redline 185F @ 2000RPM 51PSI Oil Pressure
10w30 Redline 185F @ 4000RPM 65PSI Oil Pressure
10w30 Redline 185F @ 7000RPM 83PSI Oil Pressure
I will have race data next week, but so far if you are running the car as a daily driver, not on track in colder (Below 60F) weather definately stick with 0w20.
Pressures are way too high for way too long with 10w30.
