Thanks.
I realize that laying out what to measure -- to be consistent, honest (as it were) -- isn't simple. Thus, I use:
1] # of full stops; call this an acceleration event
2] # of engine starts
3] some note of division between town & country miles
4] average mph (trip average)
5] trip fuel cpm
as the scorecard. I'd be interested to hear how you might chart this territory. Different loads not only weigh differently, but pay differently (for those new to freight onboard).
My pickup is fairly insensitive to payloads up to 1,000-lbs when in steady state driving. Over that mark is noticeable on cpm fuel cost.
And, it is intereresting how such small changes (a bit of coasting, etc) can really add up.
Do you have a SCANGAUGE or ULTRAGAUGE, an onboard OBD-II reader for instantaneious feedback? It's useful for determining throttle position from a dead stop (the blend of safe and economical).
