Just a side point - I filled up at the local ASDA and it was the first time in years I had actually seen the Diesel cheaper than the Unleaded (100.9 against 101.9). So ended up paying more for the fuel and then having to drain it all out.
I'm going to look into these devices that stop you putting in the wrong nozzle but I cannot see me making the same mistake again. If I do I won't be admiting it on here
. I still cannot believe I've done this.
