It's at the same point in my commute, so that's a consistent mark. The best approach, that loses the least mpg, is the old "slowest speed in top gear". If I start the hill at 25 mph in 5th gear (1000 rpm), hold 80-85% LOD, I accelerate to the 45 speed limit at the top, with the least mpg lost. Other gears, higher starting speed, lower LOD, all give worse results.

But climbing the whole hill at 25 MPH would be even better, right? I usually try to lose speed up hills, not accelerate. With no instrumentation, I'm just guessing. I've been thinking about this post every time I climb a hill.
