Cooler Running Oil?
Currently running Castrol Edge Synthetic LL-01 approved 0w30 oil in my 2008 E90. I have noticed oil temps 5-10 degrees warmer with this oil rather than whatever was in the car before. I also have ER dual competition oil coolers and at my last night HPDE event experienced an oil temp warning symbol with temps around 260-270.
I've got an HPDE day event coming up this next weekend and want to make sure I don't run into any more cooling issues.
It sounds like Redline and Royal Purple might both run a bit cooler. Any experiences from you guys or any suggestions on what brand to try? Outside temps are still in the 80s and 90s here in AZ.
