My next car will be a diesel. The only little niggle I have about the whole thing is how can I be sure of filing the tank with the correct fuel. Everyone I mention to that I am switching to diesel rather than petrol come out with horror stories about someone or other who have filled up with the wrong fuel.
Surely there must be some simple way of reminding those who fill up their cars to do so with the correct fuel. I have seen a few cars with stickers on or near the fuel caps to remind the driver to use whatever is the correct fuel. I am not very keen on that as I would prefer something a little less obvious. There is no need to tell the World that I am getting so absentminded that I can't be trusted to fill up a car with the correct fuel.
A very valid concern. I have a diesel car - my wife has a petrol one which I fill(!). I also have a small diesel ride on mower and a walk behind petrol one, so I am forever using a different fuel. I did fill my diesel car with petrol once as I was distracted and on a wrong auto pilot. Cost about £70 plus loss of the fuel to have it drained... I wish that one of the fuels had a triangular nozzle and filler hole. I tend to be more careful now!
The 'Fuel Angel' can replace the fuel filler cap on virtually every model of diesel car, van and light commercial vehicle to prevent the nozzle of unleaded petrol pumps being slotted into the wide-bore neck of diesel tanks. It costs about £50
