Yeah it passes the time. I just wish I could write off my gas expenses each year. :(
I'm interested to see if summer fuel gives me a little better MPG. It's still cold and snowing here in Montana.
Also something that is interesting to note: I installed cruise control in my car around the middle part of February, and it doesn't look like it has effected my MPG in any way. Still getting almost exactly the same. I actually thought it might drop a little since there are a few sections of road where the car now downshifts to maintain speed with the cruise on. Without cruise, I would just let the mph drop without allowing the car to downshift. Like I said though: no difference.
