My top GDI~GDI-T oil in 5W30 is TOTAL QUARTZ INEO C3 5W-30.

I just bought 12 quarts of their esp 5W30 and think it's probably 90+% group lll.

The M1 AFE 0W-20 is currently half-PAO-based (with some AN) and the M1 EP 0W-20 is currently fully PAO-based (with some AN). For GDI/TGDI engines, go with the M1 EP 0W-20, not with the M1 AFE 0W-20, because the former (EP) has not only a higher-quality base oil but also a higher antioxidant content (for extended performance (longer oil life)), both of which are necessary for reducing the IVD.
The M1 AP 0W-20 is very similar to the M1 EP 0W-20 and possibly even a better choice, but it's a lot more expensive.

My top 3 gdi oil is to never buy a gdi again 
Hope I can find mpfi in the future.
My wife liked our gdi. Other than that, all our other cars are mpfi.
As far as your choices , I like M1 EP. I use it along with PP in our gdi.
Summer M1 EP 10W30 & winter PP 5W30.
Some Chevron Supreme dino 5/10W30 here and there.
Recently bought some Castrol GTX Magnatec 10W30 for one older car but I may try it in our gdi once and see how it does.

What are your thoughts on the Mobil1 AP 5w20 in my GDI Focus 2.0?....I scored a bunch of it at last years AZ 'Clearance'.
I know form your post last year that it's a majority GIII unlike it's 0w20 brethren. I believe the GDI is harder on oil than the PI 2.5 version in my Escape based on how quickly the GDI turns the oil dark (soot, I think). Would I be better off doing shorter 5K OCIs on synblends, or even 7K on Supertech syn., than 10K on more expensive syns in this GDI engine? Thanks
This is the tread from last year that I mentioned:
M1 AFE 0W-16: PAO-based
M1 AFE 0W-20: 1/2 PAO-based and some GTL
M1 EP 0W-20: PAO-based
M1 EP HM 0W-20: only a dash of PAO (less than 10%)
M1 HM 0W-20: 1/4 PAO- and 1/4 GTL-based
M1 TP 0W-20: 2/3 PAO and 1/3 Group III
M1 AP 0W-20: PAO-based
M1 5W-20: 2/3 GTL
M1 EP 5W-20: 1/3 PAO, a dash of GTL
M1 EP HM 5W-20: only a dash of PAO (less than 10%)
M1 HM 5W-20: 1/4 GTL, a dash of PAO
M1 TP 5W-20: 1/4 PAO
M1 AP 5W-20: 1/4 PAO
