Excel
I have a log book in the truck.
I have an Excel spreadsheet that I use from my PDA (Dell Axim x5) and transfer to my PC.
I use a PDA/PC program called Personal Vehicle Manager.
Obsessive huh?
I don't much like the Personal Vehicle Mgr program, however, I have 5 vehicles in it, whereas the Excel spreadsheet is for the truck only, and hard copy log book is in each vehicle.
I like the spreadsheet best because it's exactly what I want it to be. I have formulas to forward the current mileage to the next row's prior mileage, calculate miles between fillups, MPG per fillup, lifetime MPG, lifetime gallons, and entries for $/gallon and total cost.
Don't forget to back it up!
