From what I've read from this thread 0W20 does not maintain Oil Pressure where it needs to be when tracking on S/C car, so would it be better to run 5W30 or 0W30 or 40?
I have JRSC with Cooler with Delicious tune with probly around 250+whp on 93.
Thanks for the input!

Answer: For track purpose, 5W40 & 10W40 will help with maintaining oil pressure for your boosted setup. The 5w vs 10w will be based on your geographical location/winter temperatures.
I run Redline 10w40 as there is no snow in the SF Bay Area, an ester based oil, and much higher temperature resistance to shear. Most individuals recommend Motul 300V; however, Redline is easier on my wallet and i'm not setting record lap times. Additionally, another popular/cheaper oil is Shell Rotella T6 among the Subaru WRX/STI community. Now i'm not sure how it performs on FA20, so you'll have to research that.
My BRZ was tuned by @
Elite Performance,~ 255whp on their Dynapack - 91 pump.
- JRSC > JDL UEL Headers > Motive Overpipe > HKS Double Resonated Frontpipe > OEM Midpipe > Greddy SP Elite Axelback.
- Perrin NA oil cooler (Setrab 13 Row) + Stock Radiator.
Early June at Buttonwillow on a 107F ambient, I hit 277F oil and 244F coolant. Data captured via Aim Solo DL.

**Things to consider when running a thicker oil:
- "40" is thick and will not provide maximum protection upon startup vs OEM 0W20. (Not good for daily driver or if your commute is a short point A to B on daily basis)
- On the other hand, much better protection at higher temperatures and oil pressure.
- Noticeable decrease in MPG.

Current oil interval change - 2,2xx/3,000. I will have Blackstone Labs do the analysis on my Redline 10W40.
