mpg affected by octane?

We put 89 octane gas in instead of 93 on our trip home from relatives (91 octane is not available in Va as far as I can tell). The trip was 100% highway and we got exactly 29 mpg in our 2000 9-5 automatic 6 cylinder. We had the cruise set at about 72mph most of the time. My previous best was 26.5 mpg. Does the lower octane give better mpg or is it just a coincidence?
