A case against pulse and glide

[GeekGuyAndy]

I drive the same vehicle on the same trip for 5 round trips a day now as a shuttle service for my college. Up until last week, the best FE I could get was 26.5mpg, and I could do it consistantly. I tried EOC a few times and was able to get 29.5mpg, which seemed resonable also.

But then I stopped doing pulse and glide and tried driving with a constant throttle, at 10% most of the time, and 15-20% on hills when needed at 3 points. With that, I was able to get 28.5mpg regularly, and 32.5 with EOC.

So that means that without using P&G I gained 7-10% gas mileage! I'm going to try out several different throttle percents over the next week and see what works the best, but I don't think that I will be using pulse and glide like I used to anymore.

I thought P&G was supposed to be more efficient since the engine is running at a more ideal speed, but apparently that's not the case. Does anyone have ideas? Can anyone with a SGII try this and tell me their results?
