Castrol - Power1 versus Power RS?

Just curious here...

I've been running Castrol Power RS Racing 4T for the past few years, but confused my last Amazon order and got Power1 Full Synthetic  4T, instead.  Searching Amazon for Castrol 06078 redirects to 06112, which I thought was the usual stuff with a new label.

Now I'm trying to determine what the difference is, if any?  I don't find Power1 anywhere on Castrol's site, but from what I can tell, it's exactly the same as Power RS.

I'm not worried about it, but curious if anyone knows the story?

Power1 is a label used in England, Australia and...  Same, better, worse?  Dunno.

Interesting. Label says it's 'Product of the USA' and manufactured in New Jersey. Measurements are in US quarts, too.

I think I'll grab a quart of the RS, just to see how the labels compare...
