Any thoughts?

One of the Engineering comments from Ford during their Hybrid clinic was that they noticed about zero FE difference keeping the tank full vs 1/2 or 1/4, IIRC. The weight of gas in the FEH (or any vehicle) is a very small fraction of gross vehicle weight. 10gal weighs 65lbs vs the vehicle at 3600lbs. Many people shift more weight than that in/out of the car every day just going through real life, so the fuel weight is lost in the noise.

As for me, the HAH's idiot light comes on with 4 gal remaining...2 days of commuting for me.
