Time to Buy Gas!

I'm driving my car dry. As I was driving home from work, the gas light turned on. These are rare occurrences, but this time I wanted to get the most miles from my tank of gas. Since this is a backblip, I've refueled and I've calculated that I received about 38 miles per gallon for that tank of gas. That's the most I've ever gotten for a tank of gas. I'm supposed to get an average of 50, but driving slow enough to get those results is rather tricky. I do have to accelerate and go with the flow.
