it takes calculations as to the air/fuel mix... it knows how much gas you're using at that current moment... i tested it once, i sped up and i was getting about 9 mpg... then when i let it coast, i got 99 mpg (it was idling and i was going about 80mph). when you push the gas, the mileage goes down, and when you coast, it goes up... so it's not just some random arbitrary value, it figures it out on the fly.
yes, i have had a problem lately where i would get the low fuel light, but i would only get around 15 gallons in... which would mean there were 3 gallons left...
lol here's an idea... i'm going to drive my car until it's empty... totally empty... and use the gas tank i bought to ensure i don't need to get AAA to help my sorry ass... and we'll see what happens. it might be that there's a problem with my fuel system... i remember however when i first got my car, i put 18 gallons in and i was totally surprised because i had no clue it was that large.
