Hi Guys & Gals,
For those of us carrying out our own servicing, virtually all of us then, I don't know if you are aware of this site but check it out as a price comparison.
I've just bought some for "madams" Peugeot 2008 and I got 10 ltrs for the price of 5 ltrs and a fuel injector cleaner thrown in.

they do lots of other stuff as well.
hope it helps
