I've gone with 500ml after looking at a few 'how tos' on the internet - if I need more halfords is just down the road
Slaninar, I've got a Haynes manual, unfortunately, it never seems to say the size of any tool, just says use the tool...

Good point Ziggy, I'll make sure the bike's covered
Thanks again everyone
