Is it harmful to run on low gas?

Sounds like you'll need a new motor soon.

I wanted to clarify that my reply was only to WARN of the potential problem for running the tank low. It's not meant to scare people into thinking it will happen on a single low tank occasion, sorry for not making it clear.

Since we have a 19 gallon tank, and I put in 18.247 gallons last fill up... I'd say thats a bit closer than I wanna get.

my car like to play tricks on me... it gives me 60 miles, then suddenly drops to 40, and few miles later it shuts off

The reason you want to keep the tank as full as possible is to reduce the chance of water condensation over time from the air in the tank. Full tank = less air volume = less water to condensate. Whether this is a real problem and how long it would take for enough water to build up to make a difference is open to debate.

I was about to make this point... also if you get water too far into the line it technically can freeze at low temps and cause starting problems... this is only if you run it really low though... most of the time the water will dilute in small amounts and run through fine.

You won't pick up sediment at the bottom of yout tank because the pump suction line is at the bottom. That statement would be valid if there was a suction line at the top of the tankt rather than the bottom. I ran out of gas with 2 led's on and the car woudn't start up (started going up a long hill....so embarassing lol). Also a reminder!!! If your car shuts off at that low of fuel and it doesn't fire up when starting it, push the button again to turn it off, othewise it will keep trying to start itself and you will burn up the injectors.

Recently, someone had asked this same question on Goss' Garage from Motorweek. His answer was it cannot cause any problems to the car as the feed strainer is at the bottom of the tank on all cars. Personnally, I would not let my car run down beyond a 1/4.

While i do admit not all cars are made perfect, but comeone this is a $40k vehicle running it until one led light on the gas gauge isnt going to do anything to it IMO.

poorazn

Shame.... I do the opposite. I fill up immediately after one led light goes out. no point risking it.
