The ZS's have a 55 litre tank and it's 8 litres left when the light stays on constant so in my 180 i'd look at getting 45 miles to running out with not changing my driving style!

I wont risk more than 10miles with the light on.

my petrol gauge is all over the place its so inaccurate. as soon as my light starts to flicker on i get gas pretty much straight away.

To be honest I think I've only seen my light once or twice in 2 1/2 years as I dont normally go below 1/4 tank.

Twice whilst driving, I have noticed my petrol guage dropping from around quarter full, right down to empty and then back to quarter in about 30 secs.

When the light stays on I dont push it anymore than 30miles.
I always put in ?30 at a time and when I have done 150 miles I know im running low. I did 80 miles on ?30 the other week and the light kept flicking on!!! was shocked! Normally get a good 28mpg though

I found the guage in mine was more inconsistent than inaccurate. With a full tank, it would do 120 miles before dropping to 3/4 full. But another 120 and it was at 1/4!! However, the last 1/4 would go at least another 100 miles before the solid warning light appears. The light never scares me anymore though as there always seems to be at least a good 30 miles left!

Is it still recommended these days not to let your tank run too low between refills? Story of dirt etc in the tank...
I have a long habit of going from completely full to almost completely dry and recording the volume so I can keep track of the mpg.

My petrol light has NEVER come on, so i can only assume the bulb has gone, as ive run it pretty dam low in the past.

They normally set most cars up so that that light comes on with just over a gallon left in the tank so around 30-40 miles usually.

Don't go too low too often as any crud or corrosion will give your fuel filter some real grief.

I bet both times you were mashing the peddle in the carpet.

Combination of fuel sloshing around the tank and the predictive gauge reacting to your driving.
