In steady-state driving, there's a direct relationship between gearing and economy, up to the point the car can no longer maintain speed in top gear because it's so tall. There are very few exceptions to this. If you have shorter gearing, you're going to need to use pulse and glide to reach maximum economy. If you're using p&g, taller gearing will provide much less benefit.
