bikin' Ed,

I do hope you'll update your gas log for the Miata. People on the board can be more helpful if given more information.

I suspect Daox is right. With a small frontal area and probably an engine that's geared "short" for higher rpms, you likely can gain a lot by cutting the engine often. Because the fuel needed just to make it turn is substantial, especially at the higher rpms. Looks like it's a standard tranny so coasting with engine off is a definite possibility.

Since it's a '96 it's probably OBDII? Do you have a fuel economy gauge or just using the odometer and fuel pump data.
