Fuel consumption

Thought I'd drag this old thread up instead of starting a new one.
Just wondering how much petrol you guys can get in your tanks?

I've got a naked gen 2 and from when the last bar is flashing to the first click at the pumps is only about £8?  I honestly struggle to get more than £10 in it most of the time and that with tesco premium fuel? The most I've managed is about £12.30 and that was sitting there for about 3 minutes forcing every last dibble in.
I only got 89miles from it before I needed to fill up again too but that's probably down to my riding haha

Doesn't seem right to me, from completely empty to filling it right up is about 18.5 litres, at the present cost £20.

I'd be inclined to carry a litre of petrol and actually run out and see how many miles you do - even proper thrahing should see 120miles.
