    Actually, I can only run 94. 93 from some stations will work.

    Gas is gas. It burns. My truck drives. I use regular. There's no difference whatsoever if I run 87 or 92, and if there were, it'd be so minute that the extra mileage wouldn't offset of extra cost of the higher grade. Gas goes in, fumes come out, no matter what you put in the tank.

    But, on a sad note, the big Freightliner gets better gas mileage then the GMC - even when loaded down!

    I run 87 as per the owners manual. Plus it is down to $2.50 here in the Communist State of Kalifornia.

    In the Burb I run 93 octane but in everything else I use the 89 octane ethanol blend. The blend is usually cheaper and supports the local farmers. :D

    I use 87, I don't see enough benifit running a higher octane to justify paying the extra price.

    87

    in fact, 92 makes most of my vehicles misfire something terrible. I only have 70's low compression smog monsters

    I run 93 in the '56 but 87 in the other three vehicles. They actually had a service bulletin come out on my Ford saying not to run above 89. I checked the mpg with the different octane ratings on the Ford and there was no difference so I follow the money line....
