Not unless the fortuh gear is overdrive, which most four speeds aren't. Most three and four speed transmissions are a 1:1 ratio in their final (high) gear so the engine is turning the same RPM's, for any given speed, in both. The only thing the 4 speed does is give you closer gear spacing so the engine doesn't have to rev quite as high between shifts. Gas savings would be minute if any at all.
