I'm generally concerned about evaporate pollution from filling-up too often. We get quite a few "Ozone Alert" days in the Summer, so we know it's a problem. I let it get close to E and completely refill. Better for FE tracking too.

On my last tank (a near best 41.6) I had a passenger for 50 of those miles. For my car, the average adult weighs more than a full tank, so there has to be something to momentum with my driving style (it was mostly highway driving, which, from what I've observed, is benefited by extra weight).
