If it's already been discussed, I missed the post.

I was thinking, since we hybridians consider every angle from tire overinflation to pulse and glide techniques to eek out more mpg, is anyone in the practice of only partially filling his or her tank in order to save weight and therefore increase mpg. If so, what have been the results?

As has been frequently discussed, a lack of momentum or starting from a stopped position is a significant factor we battle in fuel consumption. We know that one can pretty easily drive ~200 miles on 1/3 tank...that same 1/3 tank weighs 100lbs less than a full tank of fuel and although we could hypothesize that 100lbs wouldn't matter much, we don't know what effect 100 extra pounds might have on our fuel consumption unless it's been tested. Has anyone tried this? Anyone want to try it?


I thought I'd get the community to 'weigh' in on this 'heavy' issue.
Pardon the puns.
