Stalling Issue When Low On Petrol

[starwarz]

R34 25GT Auto.

Last day i have to go uni is wednesday so that night is when my petrol is running low,

im always running late to uni so i skip the petrol stations on the way thinking ill fill

up on the way back,easy because their is a BP 2 minutes down from uni on james ruse drive from

uws parramatta. Anyway noticed driving to the petrol station it stalls when i REV scariest drop was from

3k down to somethng like .4k and it did this quite a bit on the way. Its totally fine when idling, the neddle

does not move about its at a constant. When i fill up no stalling at all, gave it the trusty performance test

to be sure, still seems weird it would stall due to low petrol i thought it would just turn off completely once empty, unless

something is actually wrong.

Honestly, I wouldn't know whats fact here but in my opinion, I think that would be a normal thing when your running on fumes. When you rev, you're putting more fuel into the motor to get the RPMs up, hence if your car is running on fumes then its not getting enough petrol run at the RPM you are after, hence choke. How empty are we talking here? Like right when the fuel light comes on or quite sometime after?

I get about 420KM before the fuel indicator comes on. I've managed to squeeze about 455KM before I pussied out and filled up. But I've never experience choking or stalling.

If I'm wrong, correct me, no harm done. This is how, to my non-mechanical knowledge, it would work.

I suggest do what I've been doing for the past few fills. Get yourself a $20 Jerry can from SuperCheap. 10Ls would be sufficient. When you run low, have the jerry can in your boot and drive till it runs dry to see how many K's you can squeeze at max and find your safe spot to fill up.

Said above, 455KM on a full tank of Premium 95, no choke or stalls. Filled 10L from the jerry can cause I didn't want to die off on Parramatta Road or M4.

If your down to 5-10L in the tank then the level of fuel would be an inch or so, not hard to work out that it might start sucking air in when the fuel washes about the tank

I was thinking along the lines of that because lately these last 2 weeks i have been playing Russian roulette with my warning light due to my extreme laziness

to fill up in peak hour conditions, so warning light was maybe on a good 40-50 kilometer i guess maybe more. I have no real knowledge on the fuel system

other then fuel pump circulates fuel to injectors, i have ran my mums Focus pretty low 10km or there about and no stalling (love digital readouts).

I got a 5 liter Jerry Can think i used for my 2 stroke moped, got a empty it and fill it up for these situations, i might have crap fuel economy because

it feels like its been drinking like a Russian so i might as well test that.

Do that, but remember when your motor runs dry, I think you'll need more than 5L. If you Run 5L, good chance the fuel lines leading from your fuel tank to your motor is all air and would suck up quite a bit to fill the pipes and motor. 2.5L engine, leaves 2.5L in the tank, not to mention the fuel lines. You'd most likely still be sucking up air with 5L. I took this into consideration when I got my Jerry can and I'd say 10L would be best bet on the safe side to get you to a servo. Run the car dry on non-busy roads or on weekends so you don't stop in the middle of heavy traffic.

Yeah man your right, ill just grab a 10 liter from Repco for 20 dollars its good to have with the little can.
