Here (Italy), thank to (a lot of) taxes: 2,3€/l for gasoline and diesel (9,5$/gal, 7,28£/gal).
I've just put 30€ of LPG in my car (0,9€/l -> 3,7$/gal, 2,8£/gal).

Yep...EU members get it in taxes.

We're not in the EU any more but we still get hammered for tax 

I'll shut up now, or I'll start getting political, then I'll have to ban myself 

 

Here the region I live in Switzerland the actual price for:

95 Octane: CHF 1.97 per liter (1.93€)
98 Octane: CHF. 2.02 per liter (1.98€)
Diesel: CHF 2.23 per liter. (2.18€)
CNG at our company: CHF 1.80 (1.76€)

Note that we always pay around CHF 0.20 per liter more for Diesel!

I actually seen such enormous gas price difference at my area: USD $4.29 per US gallon for Unleaded gas while USD $5.29 per US gallon of diesel
