I reached out to Shell earlier this year and this is what I got:

I was later told (can't remember from where) that anything tagged as "V-power Nitro+" would be ethanol-free and only the non-Nitro+ was blended.
I used to use Petro's Ultra 94 in my BiTurbo-V8 Merc and my previous BMW E90 N54 TT-I6, both with great results since I had the boost cranked up considerably. But I've been pretty adamant about using ethanol-free 91 in the Aston being a naturally aspirated 4.7L V8, so this is going to probably force my hand to start using ethanol-blended fuel in it (unless Shell's Nitro+ 91 is still ethanol-free). The RRS is fine to use ethanol since it's the supercharged 4.2L.
