this whole idea has gotten me playing with my excel fuel data again
I have run the numbers to see how much I have saved just with driving tweaks: $284 over about a year.
With my mods I have saved $692 since the start of 2011.
for a total of $976
Its a good thing I modded my car, that over doubled my savings rate.
I think it is a good idea for all of us to look over our data and see the savings!
