Okay... So, I drove my truck to college without looking at the gas gauge (65 miles)... And when I got there and parked my truck - '01 F-150 5.4L (see sig) - the low fuel light was on. The gauge is just right on E (not past it). So, 3 questions: 1. Once the truck goes into auto reserve (low fuel light), how much gas is left? 2. The distance from my college to Thorton's (only [closest] station in which I will use the gas in this area [other's have bad gas]) is ~3 to ~4 miles away... should I risk it? 3. I have a can of Seafoam... (yeah, this is gonna sound like a bad/dumb question)... but, if I put it in now and went directly to Thorton's to fill up my gas tank, would that hurt my truck? --- I was planning on putting Seamfoam in my tank anyway since (at home [in a very rural small town]) all we have is Casey's gas (eeyup, ik, it's bad quality, hence the Seafoam)... but, I just don't know what to do. I don't know how long I ran on reserve... I've heard rumors that there's still a gallon or 2 left once the light comes on. So, besides the fact that I don't want to run out of gas on the way to the station, I also just don't know if I'd hurt anything by putting it in now... Sooo... what do I do?
