Castrol SRF is obviously the superior product and the cost is reflected. I have always stuck with ATE Type 200 because I have never had issues with it, it is much more cost effective and half the cost. I bleed before every track day so the cooked product is removed. Over course of a season I am sure things get cycled through at least 3X. I have had a fail with an old container of AP Super 600. Container was sealed but was dark upon opening and not knowing differently (thought this was the color of the product) found it to boil real easy. complete flush required...anbd was appaently given bad advice as its not compatible ...... well that was years ago now.
