Sorry - this is a bit off-topic but since we're all motorists I thought some of you might know the answer to this question...

Is there a good website (or mobile phone service) that can help you find the nearest petrol station selling super unleaded fuel?

I ran into a tricky situation this weekend where I was very close to running out and had to settle for normal unleaded to keep the engine running until I could get back to my usual filling station.

Thanks for any handy hints!

I've found that all Shell garages and Sainsburys supply super unleaded - you'll probably be able to get info about locations from their websites I should imagine.

All BP and the vast majority of Texaco do as well, though nothing is as good as Optimax in terms of price or RON.

I think this is the site you are after:
