Well, I finally filled up today after a month and a half. 859.3 miles on 13.25 gallons for 64.85 mpg. The dash showed 70.4, which is about 8% high, which is about the average for my car.

I don't think I did anything different for this tank; right away when I filled it at BP, it seemed different. More pep than usual, and I could hold speed using less gas. Maybe the mixture? This is by far the best tank I've had -- the previous was 61.1 mpg (at the pump).

I almost forgot how you fill one of these things. I did have to take a second to remember how you flip the release lever for the gas lid!
