I noticed at AZO that Castrol Syntec is now Castrol EDGE with SYNTEC Power Technology. My question is, have they changed the formula for GC 0W-30 that we in North America use and love?
"Why is Castrol SYNTEC 0W-30 formula not changing right away?
The 0W-30 is a global European formula. The volume is much higher in other markets than it is in the US and those markets require the specifications of the current formula. Like 5W-40, the packaging on 0W-30 will remain SYNTEC until we receive OEM approvals on the new name."

From their FAQ, question 9:
