Well, your choice, of course.

And you could be right (I often wonder what it will be like when the time comes my starter dies & I have to replace it. Will I wonder if it was all worthwhile at that point?)

One thing I've noticed though, is with the ScanGauge, I can see my average mileage for the tank drop while sitting at a stoplight idling. - really drives home the concept (at least it did for me)

Oh, I updated my "garage" with a picture of my other car (Suzuki Swift) with the duct tape grille block that saved me almost 2.5 MPG. Just click on "The White Gnat" in the column to the left to see it. Cost was a roll of duct tape and maybe 15 minutes to "install". - a pretty cheap & easy 2.5 MPG!!!
