Update!!!, Berlina Bullitin
Ran a bit low on fuel over the weekend while havin' a blast around and having read somewhere else about the advantages of running on super unleaded (or its various brand versions) and that it was the closest thing you can get that is readily available to the original 5 star grade that these engines were designed to run on (apparently) I thought I'd give it a try.
Well, I dunno if its just psycological but it does seem to be smoother, quicker and its definatley lost its tendancy to pink occaisionally

. The only disadvantage I forsee is that it empties your wallet more quickly at over £1.00 a litre

(thats not good in a car that drinks like a fish!!!). Maybe i'll just use it as an occaisional treat.
