But in coding there are 3 (I think) fuel tank profiles selectable but whether that handles capacity or shape I do not know but someone may

Just because there are 3 different tank types (profiles) to select doesn't imply that any effort has been made to linearise the fuel gauge - indeed user experience suggests there has not.

 

In my experience of owning/driving cars of many makes for over 40 years the fuel gauges have never been linear; on every car I've owned/driven (as far as I can remember) between full & 1/2 the gauge moves down slowly, between 1/2 and 1/4 the gauge moves quicker and between 1/4 and empty the gauge can almost be seen moving down.

I think we're all agreed that there is no "accuracy" in our fuel tanks or gauges, but almost all of us employ our own pretty fool-proof system for filling up before we run out.

Irrespective of dash data, I fill up when it suits me, mainly using the distance travelled since the previous fill up.

As an occasional bike rider, where the fuel gauge is a bit of decoration, filling up based upon distance travelled is the most reliable way to go. Always combined with When It Suits Me, relative to where the next journey will take me.

Almost always fill up at the end of the day as I hate starting a journey with a trip to a fuel pump.

ps - currently loving spending Skoda's free fuel card that came with the car.

When your misses goes into labour and you drive her to the hospital, just remember when you run out of fuel, that the carpet and seat cleaning bill was your own fault.

Plus she will likely grab something vital when the pain gets bad and squeeze hard.

 

I get you might complain about it, but maybe you should just do what your heavily pregnant wife wants for a while?

At least the gauge appears to err on the side of caution as opposed the Hyundai ix35 hire car I had this week. On my way back from Gatwick it was showing a range of 115 miles when the light came on, then dropped to 105, then 85 and then 65. Ten minutes later zero miles and the fuel light began to flash. Cruise was set at 75 (ahem) so no erratic driving, purely motorway. Regarding the OP. I'd say just make sure you top up the tank until the OH goes in. Common sense really.

On most cars the range is calculated from the average of a set number of miles just travelled. IIRC Skoda use the last 30 miles/50km.

I think the float type sender went in the 1970s. A more reliable type nowadays with no moving parts. Cork gaskets and smeared over fuel immersed wire elements anyone? Me, I think the modern gauges with predicted ranges are wonderful and helpful.

Heh, she's at it again (4 weeks to go), she's got the octavia this time though.

Old post but modern cars still use a float, cheap, simple and very reliable. And yes its all still immersed in fuel.
