2021 Model Octavia IV 1 Litre Turbo Petrol Hatchback.

I'm trying to work out the capacity of my fuel tank. I filled the tank a few weeks ago and zero'd all the settings, today the readings were "miles since last refuelling - 495", I had three Bars still lit on the dash, Range was showing 165 miles. The tank took 40 Litres to full. My owners manual say I have a 40 litre tank which just can't be right given the above information.

Any thoughts or comments?

Fuel tank size is 45 litres

Thanks, so at what point should the Reserve light come on, given there were three bars left on the fuel gauge?

Just to add to my last post, the manual says reserve light should come on when 7 litres are left so that doesn't relate to a 45 litre tank if it took 40 litres?

Auto express say 47.8 litres

By your use and putting 40 litres in means it has to be bigger than 40 litres unless you pushed it to the garage

No, drove in to Morrisons in York and paid £1.529 a litre. The tank has to be 45L + by my reconning.

I reckon the tank is 45 litres plus whatever fits in the pipe to the filler cap. I am often putting 42-43 litres in mine, usually around the time the bottom mark lights up red - at which point I have about 65 - 85 miles of range left. The variation in the range is down to the type of recent journeys and average fuel economy. If several short journeys at around 45mpg then the lower figure, but I'm often doing longer trips and can get high-50's to low-60s mpg. Have done over 600 miles on a single fill - perhaps pushing my luck, but thankfully not pushing the car 😉
