i was half asleep this morning when Martin Lewis was on GMTV today talking about how to save money on fuel but managed to catch the drift of the normal sort of stuff. You know "don't over fill your car", "keep tyres inflated", "look around for cheaper fuel", "make use of supermarket money back schemes" that sort of thing but he also said something about not going past the clunk when filling the car full because this just goes into the overflow and is wasted money. This one hit me as i'm always doing that.
So I looked on his website and found this little bit "While filling up to full isn't great as it adds weight to the car yet if you must, don't keep going after the petrol nozzle 'clunks', because you're overfilling."
Is this true that it's wasted money? I've filled up a few times to the point that the petrol is visible in the pipe but not overflowed, is this pipe not just an extension of the fuel tank and the petrol will run down the pipe and into the tank as fuel gets used or does it get dumped the moment i'm off the forecourt?
I don't really know much about cars and their inner workings but i think this is just twoddle, am i right?
as long as you keep the petrol in the filler tube, you're fine.
