When the yellow light comes on to warn of low fuel and the display says 0 miles left, how many miles or how many litres is actually left???

About 20 miles

cheers, should be enough there to get to the shell garage tomorrow. does the fuel gauge go to red on the maxidot when you go onto the emergancy tank or when you go completley dry?

When the warning light comes on I have 45 miles to go, but that tells lies

When it tells you it has zero miles left, it just means the tank float is at the bottom of it's travel

cheers, it was on 50 miles left when i left work last night, 35 when i got home (10 mile journey), left work with 25 miles left on display and arrived home (10 miles later) to it shopwing 0 miles. need to drive 8 miles tomorrow to get to the nearest vpower stuff

Like I said, it tells lies You should be able to make no problem

There is also a substantial delay from the tank level sender. I have pulled up at night on 0 miles and it's been back up to 5 miles the next morning once everything has settled down

Don't run it on an empty tank for long. The fuel pump is immersed in the gas in the tank, which also cools it down.

Without it, it will overheat and stop working. On mine, the light comes on when I have about 6 liters left in the tank. Good for about 50 miles highway or 20-30 city.

cheers, i just want to clear the system out and put fresh fuel in it to make sure there is no contamination or stale fuel in the system

When my warning light comes on it says it has 50 miles left in the tank....

yeah i had the 50 mile warning 20 miles ago and it shows 0 now. just have another 10 miles to go to get to my nearest vpower supplier.

It will tell you different miles left according to how you are driving at any given moment.

well i got to the petrol station before it tried to conk out, filled up with 56 litres (ouch at over £60).

Wow! - you must have been running on fumes - the tank capacity is supposed to be 55litres! I'm not sure if this includes the reserve or not which I think is just under 1 litre.

i thought reserve was 7 litres?

You have the rated fuel tank capacity, of which the reserve is the last 6-7 (depends with tank/engine size) liters, when the warning light is on, then you have a hollow contraption close to the top of the tank where the fuel vapors are supposed to be able to expand if you have a fuel tank on a hot day, which may also hold some fuel in liquid form, if you force the pump past the clicks.

Most manufacturers advise you only fill past the clicks if you are starting a longer trip immediately after, so that the fuel level drops soon enough.

I would advise against this, however, mainly because the fuel not injected into the engine is sent back to the tank, but hot (typically 60-70 C), after being squeezed through the fuel pump, filter, lines, etc. The diesels have a fuel heater extra, but also a radiator on the return pipe, cooling it down some.

cheers for that, so in theroy my tank is 55 litres of which is 7 litre emergancy, meaning 48 realtime main tank?

The reserve is the bit after the fuel warning light comes on.

The 48 litres is in the normal part of the fuel gauge.

Either way, at least you now know how far you can go after

the fuel warning comes on

yeah not something i want to do again, unless im trying to clear out the existing fuel. must admit it seems much much quicker now and more responsive.

It has made me cringe reading this thread, I try to keep to half a tank most of the time.

I would go down to a quarter of a tank on a long journey, but to operate on the low level warning light, no thanks.

One other thing to keep in mind is to keep the tank as close to full as possible when in very cold weather.

The reason is that the air, (which is also found inside the tank, on top of the fuel ) contains moisture, which condenses on the cold tank walls, then drops down to the bottom of the tank, where it can be sucked into the engine lines. Naturally, the less fuel, the more air, the more moisture that can form.

This is less of an issue with today's plastic tanks (like the Octi should have too) because they are worse at conducting heat, but it can still lead to problems, and it's very simple to prevent.

I was told that the bottom of the tank could be a bit cruddy and it was best to avoid running it right down. But then I suppose the fuel intake has to be at the bottom anyway.

I like to have 1/4 of a tank anyway. The Octy is too big to push.

this is a new car well 8 months, so it wont affect it too much, cant say i will do it again, but at least it gives me and members here an idea of how far you can go on a warning light lol.
