Most likely just recommended for optimal MPG. It's probably better to have a car tuned for 95 if your using it every day TBH (because it's cheaper).
Octane is going to have very little real world affect on economy.
I highly doubt any production engine is going to be anywhere near knock limited at the sort of load/rpm an engine is going to be operating at during typical cruise conditions
). How do the pay from your phone work if your not supposed to use mobiles on a forecourt?
