Will I spend the extra money on premium again? Nah, it wasn't that much of a difference to me. Did it prove to me that you do, in fact, get better fuel economy with 93 octane? You betcha, and I bet that I could've done better without the mountain run, as well.

Your 'test' was not scientific....did you every consider that you could fill your tank up with 87 octane and drive your same route 10 times and get ten different MPG results? Your test lacks controls to be able to draw conclusions. Funny how you do your test once, and draw conclusions....did you attend college?
