thx for the heads up Dre, will watch closely and compare what little baseline I have 53.6mpg lots of engine on coasting. I figure I currently have a shot dmf because of the clutch drag and because when I rock the car back and forth in gear, it sounds like this video (sans George Harrison background music) from the bellhousing. But the car has never appreciated being bump started, so that will be interesting.
but to the OP, it won't make much difference if you are cruising at a constant 70mph. You would have to be pulsing and gliding to really take advantage of the reduced weight. I do that a fair bit. And p&g has higher returns at slower speeds (though aero mods help the high speeds), fits in especially well with around town driving once you get the hang of it (will beat the pants off your hiway mpg)

1) I can run 100-150 rpms less with same load.
2) Starting is much smoother.
3) bump starting is now effortless vs cumbersome (could never do it with picky passengers)
4) idle is much more quiet
5) other drivers are much more apt to drive it at lower rpm's than they were before (small sample size of 2).
6) shut down is now smooth and silent.
Best sum it up is smooth, smooth, smooth.
EDIT: as an FYI: I thought I had a DMF to begin with . . . . previous owner swapped it (apparently)
