Castrol Syntec 0w30 European Formula Opinions?

[dejacky]

I just switched from Mobil 1 10w30 synthetic oil to Castrol Syntec 0w30 European Formula "Made in Germany" synthetic oil after reading a few positive oil analysis results and favorable reviews. The car feels smoother overall and seems to start easier. What do you all think of this oil compared to Mobil 1 10w30 synthetic (that seems to be the norm for toyota JZ turbo cars)?

I use it

GC is a PAO synthetic...Mobil 1 is a Grp III hydrocracked dino oil.
