using 87 will make your engine ping and could cause some serious damage. and it does lower your economy (MPG).
why even bother? you will be saving about $0.20 per gallon, so on a complete fill up you'll save less than $4.00...
just clip a few coupons before you go to the grocery store if it's that big of a deal.
