Ok, I know there are a ton of threads on MPG, etc...this is a bit different.
Each time I get gas I write in a little book, the following info.
Date
Station Name
Station Location
Price Per Gallon
Total Cost
Total Number of Gallons
Odometer
Trip Odometer (reset at each fill-up)
Type of Gas
I also note the date and mileage of my mods.
I decided to enter this all into a spreadsheet and see what numbers I come out with. Here is the summary.
OK...so I finished the spreadsheet and re did the numbers...here is what I got.
