ya im a dumb ass...i knew our fuel tank was 14.5 gallons so i was just dividing 320 by 14.5..lol just filled up when my gas light came on and i only put in like 11.6 gallons and i got 311 miles to that tank...lol sry for the pointless thread
I suggested it before ... how about putting your average speed with your mpg? The trip computer tells you this. I think it's relevant.
Also it helps to stay off the throttle when it's not necessary. There is no need to stay in the throttle when you know there is a red light coming up, or a stop sign. I also use hills to my advantage - since I use so much gas going up the hills, I typically coast down the other side. Basically you need to analyze every moment you are on the gas and make adjustments. This is also where it helps to monitor an instant MPG meter, to get a ballpark of how much gas you are using for that moment.
I always laugh when people get impatient behind me when I'm coasting towards a red light in the distance, burn past me, slam on the brakes to stop for the red light, then I roll past when it turns green because I didn't even have to stop.
