I thought this was a little humorous. I started listening to Harry Potter on audiobook and my MPG went up a bit. Not sure if it was because it's alot more calming than the garbage that plays on the radio or if I was letting off the gas so I could hear the dang thing (it was very silent, even with radio on 50/63 volume)
The MPG isn't really a ton more and could be some weird coincedence but I thought it was worth smiling about once i was done listening to it and seeing it drop back down that little bit

On another note, I drove forever with the gas light blinking, when I filled up I put in 11.239 gallons... Isn't it a 11.9 gallon tank? haha. Whats the most you have added?
