I normally run 89 in mine but last two fill ups I put 87 in it with the gas prices going up. I can honestly say I notice that my engine runs alot smoother on 89 than on 87. My morning start it seems to idle rougher with 87. Will put 89 back in her next fill up. Didnt notice any milage difference, worse or better. Seems to get the same based on my driving habbits.
