I've only ever used standard fuel but I think I'm going to upgrade from now on.
I do less than 5000 miles a year so it won't break the bank 
That equates to a very reasonable £2.75 a month, there or thereabouts

Or put another way, 1/2 a pint less per month in the pub. But if I were you, I'd save the money bi-monthly as half a proper drink just doesn't look right....
