I'll take a last stab and see if we're done.

Oliver, I think you're wondering whether the system will "learn" and adjust itself to you. Not in this case. Every time you fill up the settings will remain the same with the warning coming on at the same point as you empty the tank.

 

I never thought about this myself until I bought a EFI based Polaris ATV back in '04. It states in it's manual that in-tank fuel pump is cooled by the fuel and to not let the tank go dry. While it is not pumping a lot of fuel it is under high pressure so that may contribute to the heat production. I'd think this would probably occur with my G's fuel pump as well. Just my 2 cents. :-)

 

It appears from SM that fuel level sensor is set to go off at (3-1/8 gallon, 2-5/8 imp gal) or less.

 

Careful Threach... you don't want to offend anyone!!!

 

Aeson, I didn't mean to flame you, but like I said I used the search function and did NOT find my answer. So the "use the search it has been talked about" comment annoyed me. Didn't mean to blow up on you.

Thank you. I found the answer I was looking for. I really appreciate the input.

 

It's any fuel pump in the tank, everyone I've know who has run out of gas, with an FI vehicle, pump in tank, has eventually had a fuel pump failure. What I was told is the gas serves as a lubricant for the pump.

 

I'm pretty careful at this point to never go below a 1/4 tank before I refill to full in any of my motor toys and vehicles.

 

Last time I remember that my car was really low on fuel and it went saying 30miles left ‎but after that it just showed ----- left!!! it never went under 30 maybe, I never saw it ‎saying 1 mile left!!! Is this normal?‎

 

I try to keep my car at 3/4 to Full at all times. I guess it hurts me less mentally when I go to fuel up and it only costs me $8 - $10 haha. But I do it like every 2-3 days :/ At least I work on a base where most of the time gas is $.05 cheaper ><

Oh ya, question. How bad would it hurt your car if you put regular gas in it for about 2-3 months not reallizing that you should only put premium in it because you're too much of an idiot to reallize the inside of the gas lid says "premium only"....ya I did that

 

shouldn't be no big deal... the knock sensors will adjust timing seamlessly, sometimes you have to get regular grade fuel... you can also just drive the car normal, ie, stay out of the throttle, but not much fun with these cars

 

Why??

 

A little food for thought.

I recently parted a car out, and in the process, sold the gas tank. The car had 105k on it. I didn't want to store the tank in my garage with gas in it and the top open. I drained the gas into my mower gas can. Let me tell you, there was NO sediment buildup in the tank. NONE. I was suprised myself.

So, from my experience, the scum / sediment at the bottom of the tank statements, don't really hold up.

 

I've designed fuel tanks and fuel pickups etc...
First you never have your fuel pick up at the very bottom of the tank. So unless you have a tank with a whole lot of dirt/sediment, that isn't a concern. Your fuel pickup has a rough filter and then you have a finer fuel filter. You design to have the fuel gauge go to E or in the red once you get to a conservative fuel level (15-8%) of tank volume. Fuel does serve as a pump coolant, a large tank of fuel is a good "heat sink".
Fill up like a normal person and your good to go.

 

I have not filled up with my G with a full tank of gas. Gas is too expensive and I'm too broke!
