Right then gents, Today, as I was filling my 2.0fsi up with petrol (don't worry about me!), some bloke enquired about what effect 1.2 litres of petrol would have on a diesel. He said he was filling his motor (a Vectra) up with juice but by the time he'd realised he'd got the wrong nozzle, he'd put 1.2 litres of petrol in it. He said the tank was pretty much empty and was contemplating just filling the rest of the tank up with diesel and carrying on regardless. Would the petrol (approx 2% of the tank capacity) be so diluted by the diesel that it wouldn't matter, or would it wreck the engine? I suggested that he phone the RAC or someone and ask. By the time I'd finished filling up and paid, he was sitting in his car with his phone to his ear. So I'm just curious, would he have got away with it if he had just driven the car off?
