I think it is about 1.81 for 95 octane fuel in Zug. I was astonished that just 15km away in Schwyz it is about 10 raps a litre cheaper. I truly thought that the petrol station I saw was having a promotion, then I noticed it on the rest were charging the same. Just goes to show how different cantons do have different prices (and how living in two different countries with fixed petrol prices tends to make you stop looking at the price)
