Unleaded - any octane.
[EDIT] The Mini Cooper S (ie supercharged version) suggests Premium (91 octane) but this is a highly debated point on the internet. After much reading the general consensus was to run at least 2 tanks of regular and note your mileage, then step up to the next level of octane and do the same thing. Keep increasing fuel grades until your mileage stops improving. Note that when doing this you should try to keep your driving style constant (both speed wise and highway/city amounts). Personally I'm playing it safe and sticking with premium.
