NOACK reportedly on old one was 5.6%, the new one? Who knows, but it is probably average for C3 category. Mobil1 0W40 FS also had increase in NOACK compared to previous VISOM base, so same is to be expected here.
Is new ESP good oil? Yeah. Is it better than average? probably not. The old one just had much better performance than other oils of same category.
Is the 'old one' the ESP Formula 5W30 that you're saying is discontinued? The old discontinued ESP Formula had VW 504/507, MB 229.51, Porsche C30, and BMW LL04 as shown in the user review images on this amazon pages
https://www.amazon.com/dp/B00LWUWP6O/ref=psdc_15719391_t1_B00IJP5972 but now currently on Mobil's website it is listed without VW 504/507, MB 229.51, Porsche C30
https://www.mobil.com/english-us/passenger-vehicle-lube/pds/glxxmobil-1-esp-formula-5w30 and with BMW LL04, but spec wise that is the old one? Any current availability is just old inventory being sold off?
The ESP Formula 5W30 currently posted isn't the 'new one' though, the new one being offered going forward is ESP 5W30
https://www.mobil.com/English-US/Passenger-Vehicle-Lube/pds/GLXXMobil-1-ESP-5W30 which earned the MB 229.52 but lost the BMW LL04 ? This is supposedly due to a change from Mobil's own visom group III+ base to a GTL group III (

https://www.bobistheoilguy.com/forums/ubbthreads.php/topics/4877668/re-mobil-1-5w-30-esp-will-end) Going forward the NOACK is supposedly 7.9%, TBN 8.61, TAN 1.48.
When was ESP 5W30 released? I'm just now realizing that a lot of UOAs and discussion of ESP 5W30 probably refers to ESP formula 5W30 (like this VOA from 2007
https://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=1051856) I've gone through two cases of ESP 5W30 in 1 liter bottles, should I assume I got the ESP Formula?
