I've been very happy with my Redline oil. Ever since the car has been over 3,000mi and on Redline, my temps have been better than my first summer with the car using NEO. I would routinely hit 240F in traffic last summer. Today I was testing it and only got to 225F sitting in traffic in 80F weather. That being said, a cooler is still mandatory for track days, hence my decision to install one now.
