I don’t understand the love of Castrol SRF. It’s got a very high wet boiling point 519F but a really low dry boiling point 590F. One of the lowest of ester based fluids. Endless RF650 never gets any love but I believe the numbers show better performance with dry and wet boiling point. 622F/424F. If you change your fluid before track days your only worry should be dry boiling point. Endless surpassed Castrol a long time ago. F1 teams almost exclusively use Endless.
