Title: Fuel low warning light - how much fuel left?
Post by: honestjohn on 15 March 2010, 09:34:14
I have a GLS Omega V6 so it has a limited onboard info display. When the low fuel light comes on, how much petrol is there left in the tank?
I checked the user manual and though it seems daft, I could not find any mention.

I think around 7 litres or around 1.75 gallons, but not completely sure about this

Approximately 20 miles mate, have been there several times!!! don't do any more than 40mph, and get fuel after 20 miles, cos afterwards you start to suck up all the dross in the bottom of the tank if you are not lucky...........

Thanks for the replies. Probably best to be on the safe side and I will make it a habit to carry a spare gallon in the boot.... :)

I used to just look towards filling up when it dropped below a quarter ::) ::)

It all depends on how hard the car has been driven up to nearly emptying the tank.
When I filled mine the other day, the low fuel light was on (not flashing), but the computer hadn't started to warn me I was on my last 31 miles. I topped it up but only got 65 litres in.  ;)

on mine the fuel light comes on when 30 miles are left in the tank, at 5 miles left the fuel light symbol starts to flash, and trust me its accurate when the display in mine say 0 miles left it isnt lying....!!!!!

Hope this helps

My trip display has been as low as 4 miles remaining. Brimming the tank showed that there must've still been a gallon or so left in there.

Ive driven mine for about five miles with the display reading 0, so perhaps they vary a bit.  :-/

iirc, 8l when fuel light comes on, 2l when it starts flashing.  Really, at point it starts flashing, seriously consider putting fuel in ;D


If only I practiced what I preach ::)

orange light turns to a flashing light.  if it flashes, dont mess about, fill it up, if its orange for a couple miles, your ok for 5 - 10 miles, but whats the point waiting? u will need fuel anyway, so just keep it topped up.

I had one not had the light on for half a mile. parked it at night club, 2.30 am, im walking to a garage!! wouldnt start.

later that week, another 3.2i estate, same problem, so DO NOT RELY ON FUEL GUAGES!

A thought for you .....

All these cars are around 10 years old or more ... what crud and rubbish is sloshing around in the bottom of the tank ??  I know there's not as much as there used to be with metal tanks .. but IMHO there will still be a load.

If you run the tank close to empty, this crud has far more chance of being picked up and ending up blocking filters or worse.

I know in times of hardship it is a tempting thing to do, but IMHO it is a false economy ...  you have to put the fuel in eventually .. why not put it in 2 gallons earlier ???

Just my thoughts .. nowt else .. :)

If you've ever looked at a fuel gauge sender out of an Omega (or any other car really) closely, you'll get the strong impression that they are hardly precision components. The amount left when the warning comes on could easily vary by a couple of litres or more from one car to the next.

As for the "sucking up crud from the bottom of the tank" thing...
My understanding is that the fuel pickup is at the bottom of the tank all the time, it doesn't float up and down with the fuel level.  So I don't really see how having less fuel in there makes any difference...

Hi - on mine I estimate 30 miles left but if I let the tank drop down do an indicated 15 litres or so and then park on a sideways slope (left hand of the car downhill) it will not start.
I tend to fill up when the tank is around 25 litres.

never let mine drop below the first white line on gauge so never reach the red or light,i think it is best to use first white line as empty marker instead of chancing running out of fuel :y :y :y :y and i never trust the computer it's never accurate ;D ;D ;D :y :y :y

Found out ages ago that the best way is to fill the tank and refill when it gets down to the halfway point, it generally costs me about 25 quids and I know then that I am not going to run out.
If you must keep the fuel level low then give it a max of 10-15 miles depending on town or motorway cruising.
Its not advisable to carry fuel in the boot cos the temperature chenges can make plastic containers leak fumes as the fuel expands. Best type are the old metal srew topped heavy duty jerry cans but they hold 5 galls.

All this amazes me Alright we all run low sometimes  but why let the tank run so low, over time the cost is the same if you keep the tank full or almost empty. Some say you get less vapourisation with a well filled tank  but what about the weight.I can remember running with a low tank looking for a garage with Green shield stamps Why stress yourself keep it well topped up.

My constant running out (amazingly, I haven't yet in Omega, but have in virtually every other vehicle - personal or company!) is more due to a combination of not looking at fuel gauge and an utter hatred of standing there filling up, then having to queue up to pay when all the retards are doing the weekly shop.  The money aspect doesn't come in to it for me, as the cost is the same anyway over time.

It only gets worse when there's only one sodding pair of LPG pumps and there's someone there already filling up a tractor. >:(

Since i spent an embarrassing afternoon watching an AA mechanic patiently stripping down my Carlton carb and cleaning out the jets at a busy roadside and politely lecturing me on the perils of running on a low tank, i since use the "20 litre" mark as my absolute bottom limit -  running out of fuel can be a costly and time wasting mistake for a ha'peth of petrol  :-[
