GF-4 with its AW additive limit will ruin DC+ IMO. GF-3 DC+ is a GIII w/ 15-25% PAO, and a healthy add pack. Or less Mobil pulls something fancy out of their hat(like some of the newer, developmental additives) I can't see the GF-4 version being comparable.
It's my understanding that GF-4 is NOT in production yet.
