Fuel Tank Capacity

How many clicks of the pump did you take to achieve that?
User manual recommends not to put in any more after the second click, elsewhere I've read you should stop at the first click.

Manual mentions expansion space in the tank and there is also the volume going up the fuel filler neck. Is it possible overfilling into those spaces could add up to the extra?

Either way something seems screwy. If your gauge was at exactly 1/8 you should still have had 8-9L onboard... It would seem either your gauge is out (you were running on fumes), or their pump is very wrong...

Pumps being mechanical devices may develop faults?

After some quick reading it seems unlikely that the bowser should be inaccurate, they get checked regularly by the operators and regulators and I imagine the penalties would be steep.

If you think the servo's pump is inaccurate you can report it.

Expansion space is apparently minimum 5%, so a tank designed to hold (say) 70L must do so at a maximum 95% capacity and will actually be a 78.95L (or more) tank.

So about a spoonful either way.

And watch out for bad facts on social media!

I filled up until the bowser clicked out, then rounded off to the next even $

I have had Costco bowsers continue to pump until its running out the top of the filler before cutting out so it could be that.

I would be surprised if the bowsers were in-accurate. I was just surprised as I expected to put in 66-68 litres based on distance and avg fuel consumption.

On a side note, the fuel light came on with DTE of about 145km. Is this what others experience? I did travel about 80km before filling so maybe I was running on fumes. At least I know how far I can go.

My car is down to 110km DTE and the fuel light hasn't come on.
Last time, it came on at around 100km DTE, then went out, and then came back on again later.
For what it's worth, the manual says it illuminates when you reach 80km DTE, calculated from your consumption rate so I dunno why it should come on at any other figure!
