Shell with Nitrogen
Shell has signs all over, saying they now added Nitrogen to their gasoline.
Does anyone know what the advantages and disadvantages are?
I read enough info to stay away from Ethanol (Sunoco).
I hope Nitrogen does no harm, even at small percentages.

zook/john, our cars are N/A...u could feed them distilled vodka and they would still run strong. All this stuff really only matters to highly stressed race motors or turbo motors boosted to the high heavens.

I was reading up on ethanol and nitrogen last night, what I could find on the internet. How Stuff Works has a pretty good write up on each.

I read a few docs on Ethanol, and Porsche not wanting to public that it was bad,
(for newer engines), but definitely bad for older engines.
It was quite a bit of reading, because some of it were actual documents that
warned about damage to rubber (as in many hoses in our cars) and poly-allied
plastics (as in fuel injectors and several other components in, for example,
pumps), and also Ethanol-Gasoline separation occurring at 90 days.
Ethanol is hygroscopic (absorbs water right from air- not good) and several other points
that made me switch to Shell 91, gasoline only, immediately.
Don't worry about the 91 Octane rating, you will not notice any performance drop.
This is just a very short version.
Newer cars have better resistance to Ethanol damage, but I prefer no Ethanol damage at all.
I know nothing about Nitrogen (yet).

Shell for me
Moved to 91 and certainly no noticable difference in speed at the top of the back straight at Mosport (may be better but with the exit to 5b covered in water and cr@p I never got a good shot that proved it for me).
