If you think about it like that if you only drove on the highway to work and back you would cost yourself roughly an extra $1.50 per fill up(if the price of premium is $3.12). Multiply that by an average fill up of 3 times per month x 12 months = $54 if you just drive normal on the highway. It's all roughly estimation though  Since he just drives around town he's going to fill up more in theory. It all depends on the rpm he's at now compared to the rpm he will be at with 3.73s.

that would equate to about 1-1.5 gallon every other tank. so for somewhere in the $3-5 very other tank you get better et's and a much more fun car to drive.
i could live with that for the extra tenth that the 4.10's are worth over 3.73's.
you have also told me the average and peak speeds on your trips, far from typical highway travel speeds buddy.
