This is my dashboard... showing an empty gas tank... all the time. Seems every time I look down that stupid orange fuel pump icon is illuminated... it's become like water slowly dripping on the forehead. Kylie and I go round and round about this. She never lets her tank get below a quarter of a tank for two reasons. 1) She never has to worry about running outta gas at an inopportune time or place (is there such a thing as an opportune time??), and 2) driving on close-to-empty allows more of the sedament in the tank to get in your fuel system. I get that. Here's my thing, though, and I will likely stand by this for better or for wore until the day I breath my last breath... if I always fill up the tank whenever it gets to a quarter of a tank, according to my limited math skills, over the course of my life, I'll make possibly hundreds more stops at a gas station than if I just wait until it gets closer to empty before pullin' into the pump. And with that logic, even if I run outta gas once or twice, and it takes let's say 45 minutes to call someone to bring some gas, I still come out way ahead on the time gained chart. There. I win. [grin]
