At first this made sense to me, because I have more momentum from the higher speed, but after thinking about it and verifying today, the engine revs at ~1,000 RPM no matter what speed once I put it in neutral. So my question is why I get higher mileage at higher speed (in neutral) compared to lower mileage at a lower speed (in neutral)?
Thanks!

Because you're traveling a greater distance per given amount of time, and per given amount of fuel used at idle , at the faster speed.
To answer an earlier question in this thread, don't use a kill switch with most automatics. They typically have to have their engines running to lubricate their transmissions.
