Good work man!
I always intend to keep up with this stuff when I buy a new truck... then about the second fillup I say fWONkit.

HorsePower- if it don't scare ya it aint enough
I tried to do it but after about 2 months of gas tickets in my console I throw them out 
What is the difference of mpg's between 93 and 87?

I'm too COOL (lazy) to Choose a Custom Title!!!
It is possible to get better mileage on higher octane gasoline if you up the timing a few degrees. When I tried it I had an increase that nearly justified the higher cost per gallon but it hurt to watch how much each fill up cost.
Correct, that's why I'm curious to see how much worse fuel mileage he got on 87 cause that's not very good for 93 imo.
Nice work, Steve!
I would become distraught after viewing my cost per mile, and kill myself.

It could be even better with improved aerodynamic efficiency thanks to Adam's products from 
When I fill up I use the Notes feature on my phone and enter the total mileage on the truck, the price per gallon and how many gallons go in until the fuel pump clicks off (no topping off). Then when after I've got a couple fill ups logged, I'll put them into the excel spread sheet that calculates everything. With this method, I never have to keep track of receipts or any paperwork.
It's not too bad once you get in the habit.
The MPGs are a 6th order polynomial and price is a 5th order. I just played around with different trend/regression types till I found one I liked.
JMP?
I didn't get the 93 tune for mileage, I got it for power!
Remember, most of my driving is City, and it's a lifted 4x4 with over sized wheels and tires, not exactly the combination you want if you're shooting for decent MPGs. On top of that, I don't grandma the truck on the road, typical shift point RPMs are 3500-4000 with a couple WOT runs.
When I made the MPG graph I used the raw data, not the data adjusted for the over sized tires. Corrected for tire size, this is closer to the truth for my average MPGs:
A little better. Since I fill up 95% of the time at 1 gas station (I go so far as to use the same pump, far right up front) and 5% at an other, and always Shell, I figure I get pretty good numbers.
