Default Re: Gas mileage

I would recommend keeping track of the exact number of city miles on each tank of a gas. Just keep track of the highway miles and then subtract that from the total miles to get city. Once you start doing that you can see how much your mileage changes as a function of what type of miles you drive. For example on my truck the difference between driving 90% city on a tank of gas and 60% city on a tank of gas, is over a 2 mpg difference. And you can also make a pretty graph with the equation like this:
