Fuel Saving Tips
Many new cars have DFCO - deceleration fuel cut-off - that completely stop the fuel flow (even in non-hybrids) when coasting in gear. This adds drag, but uses zero fuel - good for downhills or slowing. To better maintain speed, consider depressing the gas pedal about 1/2" (1 cm). This adds very slight gas usage, and is very close to coasting in neutral for gas consumption. Check it for your car using a Scangauge or similar tool.
