Higher Octane Gas = Better Performance +MPG
"
Unless your engine is knocking, buying higher octane gasoline is a waste of money. Premium gas costs 15 to 20 cents per gallon more than regular. That can add up to $100 or more a year in extra costs. Studies indicate that altogether, drivers may be spending hundreds of millions of dollars each year for higher octane gas than they need.
It may seem like buying higher octane “premium” gas is like giving your car a treat, or boosting its performance. But take note: the recommended gasoline for most cars is regular octane. In fact, in most cases, using a higher octane gasoline than your owner's manual recommends offers absolutely no benefit. It won't make your car perform better, go faster, get better mileage, or run cleaner. Your best bet: listen to your owner's manual.
The only time you might need to switch to a higher octane level is if your car engine knocks when you use the recommended fuel. This happens to a small percentage of cars."

well so far in this experiment i will say this,First I did this when the fuel gauge hit the red line, when i put exactly 1 gallon of 87 i got 15.4 miles before it ended up exactly back at the red line. Then i put 1 gallon of 93 from the same Hess gas station and got 20.7 miles before being back at the red line. Also i have noticed a bit more response at the pedal, so tomorrow when i get paid i will put 17 gallons (fill up) of 93...if i get more than 260-290 then i got my answer...will keep u guys posted !
Way too many variables in your 1 gallon experiment, if you want to try it, go for it. I still say its a waste of your money if they don't require it.

Then your car is probably knocking with the 87 and fuel is quenching the real issue. Could need plugs/wires/tune-up/sensor cleanings/ etc.
