Figured I'd share.
I was running 0w20 since I got the car and installed my pressure gauge around 50k miles. Then I switched to 5w30 (51k miles) just this weekend. I have some few data I can share.
Mobile 1 0w20
No Oil Cooler and Stock
Perrin Oil Pressure Sensor is located at the oil galley plug between the AC and Intake
Temp is monitored through my OFT which is reading from OEM Temp Sensor
Located in Michigan
132psi (PEAK) - Cold Start - Average of 30F-45F
35 psi - 180F
30 psi - 190F
7 psi - 200F
2-5 psi - 210F
After Warmed Up - Average of 205F Oil Temp
20 psi - 1k RPM
25-30 psi - 2k RPM
30-35 psi - 3k RPM
35-40 psi - 4k RPM
40-45 psi - 5k RPM
45-50 psi - 6k RPM
50-60 psi - 7k RPM
Typically runs 5-10 psi lower than the rpm instead of +10psi/1000rpm.
Here is my data after switching to 5w30
Mobile 1 5w30
No Oil Cooler and Stock
Perrin Oil Pressure Sensor is located at the oil galley plug between the AC and Intake
Temp is monitored through my OFT which is reading from OEM Temp Sensor
Located in Michigan
135psi (PEAK) - Cold Start - Average of 45F-50F (warmer days)
40 psi - 180F
35 psi - 190F
10 psi - 200F
5-10 psi - 210F
After Warmed Up - Average of 205F Oil Temp
25 psi - 1k RPM
35-40 psi - 2k RPM
40-45 psi - 3k RPM
50-55 psi - 4k RPM
55-60 psi - 5k RPM
65-70 psi - 6k RPM
70-80 psi - 7k RPM
Pressure to RPM ratio is a lot better. I did few pulls with them close to 220F and at 7k it peaked at 82PSI which is I am happy with.
Oil temp seem to reach higher (up to 220) at normal driving with 5w30 but I think its because it is getting warmer and not because of the oil. 0w20 tops 215F normal driving with few pulls.
I will be installing a PERRIN Oil Cooler before Gridlife Event in Gingerman in June. Will be hotter ambient temps and will see if I can get someone to make note of the pressures after few sessions.
