In Texas there is more differences in Premium and regular than just
higher obtain. Typically 3 trades of fuel. Regular, often with fewer
detergents and more alcohol. Premium, more detergents and often no
alcohol. Mid grade fuel comes from the regular and Premium tanks.

Typically differences in detergents are between brands,
not between fuel grades. The vendors would like you to
think there's extra "good stuff" in premium (especially
now that it costs $0.50 or more above regular), but
other than octane boosters it's generally not so.

Actually Shell advertizes Nitrogen, V-power Nitro+ Premium, for better
cleaning only in the Premium.

But typically most all better brand fuels have similar additives in all
grades.




I am also dubious that premium would be alcohol-free.
I suspect if it was, it would be prominently advertised,
and I haven't seen that anywhere.

Well if it was advertized alcohol free they would certainly catch a
bunch of flack from the tree huggers.

Down here their pumps only claim "May" have up to 10% alcohol.
