Oldhammer I feel you, my mother and my lass does the same thing unless I have it at half a tank they think my cars empty and going to run out in the middle of no where
It's the other way round, here. I don't panic -- but I do feel an urgent need to visit my local Shell garage -- when The Orange Light of Doom appears: even though I know I have 75 miles of margin.... Usually, though, I fill up before it gets that far....
Mrs homeward will drive with the orange light on for a while, though: and then randomly go in to the most expensive petrol station in the area. :bang:
