I can never remember how much more fuel mileage you're supposed to have after your light comes on. I have a 99 z71 ext cab. Anyone have some stats on what this would be? thanks in advance

I know when my low fuel light came on in my '99,and my '04 also,I had about another 4 gallons of gas left.

So whatever your gas mileage is just times it by 4 (I.E. If your getting 18 MPG then you got around 72 miles until your empty)

Try not to let the fuel in the tank get that low as the pump depends on fuel in the tank to keep it cool, you will greatly reduce the life of the pump keeping your tank below 1/4 or lower. Just a tip for everyone.

Good point,I try to never go below 1/4 tank.

Not to mention that condensation can form and rust your fuel tank and/or fuel lines from the inside out, and mess up your fuel injectors. Car's can't run of water yet.

The fuel tanks on GM trucks from '99 up are plastic but yes to the rest.

Anytime you run out of fuel or run low and the pump will run dry doing this is like running your engine with out oil. It burns up the bearings & impellers. Guaranteed pump replacement is in your future much sooner.

The fuel light came on in my '05 SB over the weekend. I drove about 15 miles +/- and then filled it up. With topping it off it took 23.1 gallons. I believe (but I am often wrong) that the tank is supposed to hold 24 gallons. I figure that put me at 1.7 - 2.2 gallons (gave or take) when the light came on.

I think it's a 26 gallon tank for a shortbed. Mine was for the 2500HD and the new 07 as well. Both are 6'6 but on the 1500 CCSBs it said 26 gallons as well.

Yep,26 gallon tank on the short-bed & standard-beds,and 34 gallon tank on the long-beds.

2000 Sierra, when the light comes on and I fill shortly after I end up putting about 22 gal in. So there must have been about 6 in there, and no worries for 100 miles.

My mistake, it is indeed a 26 gallon tank. That would put a safe estimate, as you mentioned above, right at about four gallons.

I had the low fuel warning come on the HD once, and when I finally got to a gas station (was stuck in rush hour traffic after pulling a heavy trailer) I had about 2.5 gallons left.

Agreed, don't let your tank go empty like that (unless it's just completely unavoidable). I don't think I've ever had a vehicle that I ran down to "E," let alone below E. I'll head for a gas station by the time I see the 1/4 tank mark, or sooner. I never understood the need to constantly wait until you're running on fumes to add more gas. Those poor, abused, and unloved vehicles.... how sad... :dunno:

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."
