but thats just if your in an emergency and no station in site... to be honest with you, you shouldnt ever let the gas run that low in your tank because your pickup will suck up all the dirt in your tank that has gathered up over the years if you go too low... (even being a 97 youd be surprised at the ammount of junk in there)
so my rule of thumb is if i see a quarter tank left i go ahead and top her off... i figure this way i wont ever run low, and keep the gas tanks backwash in the tank and out of my engine...
^ lol the 7 never goes under 1/2 tank. then gas doesn't seem so expensive
mine is only like 30 miles..87 635csi

It depends on the series and model BMW. For e39s, the 6cyl engines have 8 liters when the light comes on, and 10 liters for the 8cyl 540i.
Running gas that low is not only bad for your engine as mentioned by saltshaker185, it will also prematurely wear out your fuel pump. The pump is designed to be immersed in the fuel to keep its motor running cool.
