Well? Maybe one program (a method of doing things) that could give some advantage.
Before you had on board engine control computors that retuned the engine automatically you had to tune them yourselves.
That pretty much ment that if the engine had any compression at all and you wanted to run cheap gas you had to de-tune the engine to keep it from pininging and doing other expensive internal damage, it ran a bit poopy, had a tendancy to run hot and if running headers, blow the gaskets out.
Surprise! The modern day ECU controlled car does it autmatically now so you can run cheap gas with out experiancing many of the ugly side effects. The thing de-tunes so it don't ping!
That does not mean it runs the stuff with performance in mind, it just runs to keep from breaking and for the most part no one knows the difference.
Untill you ask it to run hard and perform well which is the objective for some people.
SO
Go the gas pump and spend the extra 20 cents to run premium. The thing only holds 10 gallons so you are talking 2 bucks on gas now paying almost $4.00 around here. And it won't detune itself.
You will notice it until running hard, you may not notice anything else unless you run hard. But then again, that is the way it has always been.
Even back in the day.
As for 87 Octane? I use it to clean parts and kill weeds.
It don't belong in any car I own.
