Thousands of Miles of Mileage Records for My Mustang
Gas Mileage
Here's some interesting trivia about gas mileage. Have you ever wondered which brand, grade, or octane rating gives better gas mileage? Well, I've collected thousands of miles of data on a wide variety of brands, octane ratings, grades, etc. All this information is from my 1967 Ford Mustang. I have found these results interesting, I hope you do as well.
Overall Mileage
Here is a partial record of my gas mileage in my 1967 Ford Mustang. These records start with the first tank of gas I put into the Mustang after I purchased it used in May of 2008.
This table shows the brand, grade, and octane rating of gasoline I was purchasing, the odometer reading at the time of fill-up, and the date and location (when available) of the fill up. It also shows the number of miles traveled since the last fill up and the mileage since that last fill-up, as well as a running total of the mileage I have been receiving.
