I never heard/read the zero ethanol claim before, will research it - good news for vintage vehicles if true.
The nitrogen or "Nitro" as Shell likes to brand it is said to lower the friction, hence the alleged HP and MPG gains.
These claims have been verified by labs, but since Shell was paying for the bills I have to hold out a small bit of skepticism myself despite my own personal experiences.
The reason I have minor reservations allocated for doubt is that my two vehicles for the past three years were running on Costco gas. As I understand it, they were exempt until last summer from adding detergents to the gas like oil companies are required to do, because they were technically a grocery store. The exemption has now run out, I made my transition to Shell at about the same time.
Three years of no detergents, then sudden cleaning may explain a few things. However, about every six weeks I try gas from somewhere other than Shell and immediately notice a performance drop, mostly on how smooth my S10 truck idles and how perky the Porsche is.
Below are some posts on the topic in another forum from earlier in the year, plus a video:
