I was really surprised when my reserve light came on. I was halfway between one quarter and empty. computer tells me I have 50 miles to go. I was expecting the light to go on when it was closer to Empty, not closer to one quarter or just in between. That's what I had been used to. So after I filled up I checked the mpg's vs. the cpu and the cpu was exactly as I calculated with my calculator. 18.8mpg's. That is mostly 7 mile back road trips with occasional 15 mile back road trips also. I only have 1000 miles on my 35i now and it's been cold and we're still on the winter gas formula so I expect the mpg to be better come the summer. I hope so. Gas just broke $4/gal here.
