    IMO the higher the octane the better gas milage you would get. This is what I have always been told your not saving any money..yeah it may be cheaper to fill up with 87 but your doing more than you would with 93 so IMO keep what ya got and if your that worried get a beater.

    I knew I kept your mom around for a reason!

    Yeah, Brad is right. If you take your average car that runs on 87 octane normally and run several consistent tanks of 93 octane, the car will get better mpg.

    And I am not saying what I did the the right thing to do, but to keep the miles off my truck, to pollute less, and to save a few pennies on gas--I got myself a fuel-efficient, 4-cylinder DD. You might wanna consider the same...
