I wouldn't run 5W30 anything in your application unless it has an HTHS of 3.5 or higher, not matter what additives are in it. Did you switch from 5W50 to 5W30?

From what castrol has told me. The U.S. Castrol I was emailing said they cannot speak of castrol products sold outside of the U.S. Which is the gold bottle featuring fst pictured above. They did however say the edge extended performance has higher titanium then the regular black edge bottle.
I'd run Edge 5W50 for your track days if you're an Edge fan. But,I wonder if the "Classic Car" formula 5W50 was a better oil than the "Titanium" formula? Wonder if the zddp level got lowered since they no longer market it towards "classic cars"?
Congratulations on being [censored]. I was simply stating a fact that wasn't stated in this thread yet. Sorry for trying to help. Won't ever happen again
Well it's quite hard to tell when someone is joking or not when your on an electronic device. Doesn't exactly show emotion in anyway or anything. Didn't mean to be an a** about it but it just bothered me that I was stating a fact that I knew and was told that was specified in this thread so I wasn't sure the OP was aware of this or not.
