Ran out once in my GT, gave a littel cough and then died, luckily got my dad to bring fuel! Also when I had a 306 dturbo I stuck a tenner petrol in it, realised the next day when it struggled to start, luckily them things can run on anything so I took it to the nearest petrol station and brimmed it. A friend text me last year when he brimmed his TDI A3 with petrol, his words were a "proper double clicker"!
