Anybody tried the new Castrol GTX Ultraclean?

[FCD]

i could get the "new" Castrol GTX UltraClean 10W-40 SL/CF A3/B4 for a fairly good price.
I understand it's GTX syn-blend with more GrpIII stock and a stronger Add pack?
Some of you may know i have a 1988 Escort that was somwehat neglected by the previous owner and was thinkikg of trying it.

I have picked some some up on sale at $15 for 5L, GTX UltraClean 15W40 (API SN & ACEA A3/B3) but I have yet to run it.
