Even if that were true, what are we talking about here? Replacing the fuel pump once in the lifetime of the car? I think the proper response is, BFD. No offense, but this is silly.

 

This is informational. I also wanted to find out

 

I recently bought a used 2009 Infiniti g37x coupe and run it down to about 35 miles left or lower on the range meter. I can maybe stuff 17 gallons in at most thinking I'd be able to put in at least 18 when I consider my mpg of 22 ish. Does that sound right? Just trying to get a true sense of how much is left.

 

I ran my g35 up to 230K by filling up well after the light went on...I dont see this being a problem!!

 

G37 has a 20-gallon tank. I regularly let the level drop below the E mark and the distance-to-empty is stars and have never been able to pump more than 18.25 gallons. I estimate 3 gallons remain at E.

 

Yep, I know the capacity is 20 gallons. I've run it to nothing on the meter and the needle on E but haven't filled up at that time to measure it, just put $20 in at the time. UGH! This is annoying because I'm one of those people that likes to stretch whatever fuel I have if I can comfortably make it. No other car I've owned or spent any real time in has shown such a false high level. 2-3 gallons is a lot of "reserve". I know the owner's manual uses the term reserve but usually in other vehicles that refers to the amount left when the low fuel warning light comes on, or when the needle is in the red zone (which the G does not have).

I guess the only real way to find out is put a spare gallon or two in a can in the trunk, run the thing dry while noting roughly how far I can go on the warning light. Put in what I have, drive to the nearest station and fill up.

Anyone ever run out? Any negative consequences??

 

hay betty here is an article that i found from consumer report (on a quick google search cause i was curious also)
Running on empty: Low gas in the tank can be costly

i have never had a problem with my fuel pump so i cant say what it true or not.

 

Sure there are! A road closure for hours after a bad accident in very cold or very hot weather causing you to run out of gas and destroying your fuel pump

Telcoman

 

I've run out of gas in previous cars and didn't mess up the fuel pump. Perhaps I should be more specific, any problems getting it restarted after running out? Or in some cars, the tank will collapse in on itself.

 

Is it true that when low levels of gas brings all the sediments that settle in bottom of tank & filters thru car?

 

normally if stuff can settle to the bottom, it will do it regardless if the tank is empty or full.

 

Filter is there to catch sediments. I suppose the pump could ruined if you don't turn off the car after it runs dry. The ecu will run the pump to try to pressure up the fuel rails and if there's no fuel, well...

 

I recently ran my car to nothing on the range meter and the needle just barely above the E. Filled up and it took a little over 16 gallons to the first gas pump auto shut-off. Thought it would easily take another gallon but never got beyond 17, and that's topping off until fuel starts coming out the filler tube. I'm REALLY curious if the tank is in fact a true 20 gallon capacity.

 

I always go well past the range indicator and don't really pay attention to the E on the gauge.

I reset my instrument cluster mpg indicator every tank... so the mileage it shows me is the mileage for that tank. If the gauge is reading that I'm 22.6 mpg, then with a 20 gallon tank I'm good for 452 miles. You get the idea. So I always take my car over 400 miles on one tank and get pretty close to the calculated number, and the most gas I have ever put in the car was 18.6 gallons.

I am not convinced over anything anyone has ever said about sediment in the tank or overheating fuel pump.

I got to look down into a 120,000 mile Miata fuel tank with a lighted boroscope once. It was pristine inside there.

 

I always fill mine up at about 1/4-1/2 remaining. From what I understand, the gas helps to cool and "lubricate" the pump. That is not my concern though. I am really more concerned about living in a freezing cold state and being stuck somewhere with less than a 1/2 tank. Just want to be able to run the heater to keep my family and myself warm.
